Title: Navigation device for vehicle
Inventor: NAKAYAMA OKIHIKO
IPC: G09B29/00
Filed: 1994-07-27
Abstract: PURPOSE:To change a road map range which is displayed on a display screen according to a vehicle speed. CONSTITUTION:This vehicle navigation device has an azimuth sensor 1, a vehicle speed sensor 2, and a CPU 4, and after a recommended route from a starting point to a destination is calculated, a view position and a sight line direction for a bird's-eye view display are determined on the basis of the current position and speed of the vehicle. For example, the angle at which the road map is looked down from the view point is made invariably constant irrelevantly to the vehicle speed and the view point position is changed according to the vehicle speed. In concrete, the view point position is made higher and higher as the vehicle speed is faster and faster. In another way, the distance between the view point and the tip position of the line of sight is made invariably constant irrelevantly to the vehicle speed and the angle at which the map is looked down from the view point is varied according to the vehicle speed. In concrete, the look-down angle is made smaller and smaller as the vehicle speed is faster and faster. Through those processes, a road map which is wider as the vehicle speed is fast can be displayed on a display unit and a detailed road map of the peripehry of the current position as the vehicle speed is slow can be displayed.

Title: Control of taking-up tension of web-shaped sheet
Inventor: SHIYUDOU KOUSHIROU
IPC: B65H23/195
Filed: 1988-07-14
Abstract: PURPOSE:To improve the taking-up operation by continuously reducing the taking-up tension of a sheet at a certain rate until the taking-up diameter becomes an arbitrary taking-up diameter determined according to the sheet characteristics and further reducing said taking-up tension with the rate less than the above-described rate up to the completion of taking-up. CONSTITUTION:A polyethylene terephthalate film having a thickness of 12mum is set onto a paper tube having a diameter of 92mm so that the final taking-up diameter is 800mm. Taking-up is started with a taking-up tension of 30kg at first, and up to the time when the taking-up diameter reaches a switching point of 116mm, the taking-up tension is adjusted so as to continuously reduce with a rate of 40-60%, and the tension at the switching point is set at 15kg at the end. Then, up to the time when the taking-up diameter becomes 800mm, the taking-up tension is adjusted so as to continuously reduce in a rate of 20-40%, and the taking-up tension is adjusted to 10kg at the end. The switching point of 116mm is determined from the thickness of the film, tension at the start of taking-up, and the final taking-up diameter. Therefore, the generation of winding tightening and taking-up deflection can be prevented.

Title: Magnetic recording method on both sides of floppy disk
Inventor: NAGASHIMA YASUO
IPC: G11B5/012
Filed: 1986-07-28
Abstract: PURPOSE:To record information on both the sides of a floppy disk without deteriorating mutual information by forming a large azimuth angle between a 1st magnetic head for one recording surface and a 2nd magnetic head for the other recording surface. CONSTITUTION:The azimuth angle of a gap 8 of the 1st magnetic head 5 is zero as regulated by the standard of an electronic still camera and a magnetizing direction based on the gap 8 is parallel with the relative moving direction A of the floppy disk 1. The azimuth angle of a gap 9 of the 2nd magnetic head 6 is -45 deg. when observed from its surface 3 and the magnetizing method based on the gap 9 is inclined by -45 deg. from the relative moving direction A. Thereby, 45 deg. azimuth angle is formed between the two magnetic heads 5 and 6. Consequently, each fifty circular tracks 10i, 11i (i=1-50) are concentrically formed on both the front and rear faces 3, 4 of the floppy disk 1.

Abstract: PURPOSE:To improve the rate of opening in a beard introducing boles by arranging the holes such that quadrilaterals surrounded by two laterally adjacent center lines and two longitudinally adjacent center lines are formed. CONSTITUTION:Parallelogrammic beard introducing holes 12 set all gaps between respective sides of adjacent beard introducing holes 12 themselves to have the same width D. Laterally adjacent center lines 13a, 13a between respective sides of adjacent beard introducing holes 12 themselves are spaced a fixed distance W1 from each other and longitudinally adjacent center lines 13b, 13b are spaced a fixed distance W2 from each other. Further, quadrilaterals 14 are regularly arranged to be surrounded by the laterally adjacent center lines 13a, 13a and longitudinally adjacent center lines 13b, 13b. Thus, the rate of opening in the beard introducing holes can be improved without changing the opening area of the beard introducing holes and gap width between the respective sides of the adjacent bear introducing holes themselves.

Title: Production of magnesium-containing basic aluminum salt
Inventor: HARADA OSAMU
IPC: C01F7/56
Filed: 1985-08-09
Abstract: PURPOSE:To obtain the titled salt without an energy loss and the generation of harmful gases in an open vessel at and under an ordinary temp. and atmospheric pressure by dissolving the Mg-contg. aluminum hydroxide gel obtd. by bringing aluminum chloride or aluminum sulfate and magnesium hydroxide into reaction by a dissolving agent. CONSTITUTION:Water or ice is added to Al2(SO4)3 or Al2Cl6 and Mg(OH)2 is added thereto under powerful stirring to obtain the aluminum hydroxide gel. The reaction in this case is generally expressed by formula I and formula II and is exothermic reaction but the calorific value is low and the generation of gaseous CO2 is not observed. There is therefore no need for temp. control but the temp. is preferably maintained at <=30 deg.C. The above-mentioned gel is partly deformed to an Al-O-OH type and consequently the poor solubility is caused in some case when the temp. exceeds 30 deg.C. The Mg-contg. Al(OH)3 gel obtd. by the reaction is dissolved by the dissolving agent such as an aq. Al2(SO4)3 soln. or the like and the soln. of the Mg-contg. basic aluminum salt is obtd. This salt is highly effective as a flocculating agent for use in water treatment.

Title: Semiconductor device tester, and signal output device
Inventor: KOJIMA SHOJI
IPC: G01R31/28
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a signal output circuit capable of selectively outputting a differential signal or two independent signals. SOLUTION: Formatter elements 20a and 20b independently output input signals 22a and 22b to drivers 92 and 94, respectively. The input signal 22a inputted to the driver 92 is transmitted to the input 'port 0' of a time-delay circuit 96 and a selective circuit 98. The input signal 22b inputted to the driver 94 is transmitted to the input 'port 1' of the selective circuit 98. The selective circuit 98 selectively outputs either the inverted signal obtained by inverting the input signal 22a or the input signal 22b. The time-delay circuit 96 delays the transmission of the input signal 22a inputted to the time-delay circuit 96 by the time substantially equal to the time necessary for the input signal 22b or 22a to pass through the selective circuit 98. In the case that the selective circuit 98 selects the input signal 22b, a signal output circuit 120 outputs two independent signals.  In the case that the selective circuit 98 selects the inverted signal of the input signal 22a, the signal output circuit 120 outputs a differential signal.

Title: Fuel assembly and upper tie plate
Inventor: SONEDA HIDEO
IPC: G21C3/33
Filed: 1990-07-04
Abstract: PURPOSE:To achieve higher degrees of concentration and combustion of a fuel while enabling the lowering a pressure loss by arranging a plurality of water rods with a transverse surface larger than one area of a fuel unit grid adjacent to one another. CONSTITUTION:Four large-outer-diameter water rods with a transverse area larger than one fuel unit grid 35 are arranged leaving a clearance 37 therebetween in an area allowed to arrange 12 fuel rods 1 at the center area of a fuel assembly body. In this arrangement, though the area becomes smaller than would be when a cross-shaped large water rod is arranged, a deceleration excess area can be eliminated in an area in which an infinite multiplication factor is saturated with respect to a moderator to achieve an infinite multiplication factor. A coolant path 3 is formed between the plurality of water rods 2 and communicates with a passage 38 of a coolant in the perimeter of the fuel rods through the clearances 37 to lower a pressure loss. In addition, as the passage 3 is separated from the fuel rods 1 while it is larger than the area of one unit grid 35 and surrounded by the water rods 2, more void water gathers in an area with a high coolant void ratio at an upper portion of the fuel assembly thereby allowing the lowering of the pressure loss.

Title: Damper thermostat with forced full opening mechanism
Inventor: MINAMIDE MASAYOSHI
IPC: F16K31/524
Filed: 1985-08-09
Abstract: PURPOSE:To enable switching of a damper thermostat for a low temperature chamber to a damper thermostat for a refrigerating chamber by operating a lever regardless of expansion and contraction of a bellows by a projection mounted at one end of the adjust lever to forcedly full open a damper. CONSTITUTION:A lever 4 having a supporting point 5 is formed like a hook 4', and a projection 14-c is bent to the bellows 2 side. The bellows 2 is expanded and contracted according to an excessive change of a heat-sensitive cylinder 3 to turn the lever 4 centering around the supporting point 5. A damper 6 is fixed to the forward end of the lever 4, and the operating value of a damper thermostat is adjusted by changing the screwed amount of a screw 9. When the damper thermostat is for a low temperature chamber, a cam 13 is rotated within a range where the projection 14-c is not brought into contact with a belly portion 4'. When the damper thermostat is for a refrigerating chamber, the cam 13 is rotated in such a manner as to contact the belly portion 4'. Thus, as a controller, the damper thermostat for the low temperature chamber can be switched to the damper thermostat for the refrigerating chamber.

Filed: 1995-06-20
Abstract: PURPOSE: To obviate the occurrence of unnecessary diffracted light and to improve the accuracy of detecting error signal and the efficiency of utilizing light by disposing a λ/4 plate between a hologram element and an object lens. CONSTITUTION: The λ/4 plate 90 is disposed between the hologram element 2 through which a light beam passes twice back and forth and the object lens 14. The hologram element 22 is provided with a polarization beam splitter 100 which is bisected by a dividing line near the optical axis and varies in diffraction conditions with the dividing line as boundary. Thereby, the component emitted from a light source 11 is diffracted and on the other hand, the polarization component of the return light rotated 90 deg. in the plane of polarization by the λ/4 plate 90 is transmitted through the element. The five beams generated by the diffraction in the forward path are not diffracted but transmitted in the backward path so as to be guided to a photodetector 16.  The generation of the diffracted light is confined to the forward path alone and the generation of the unnecessary diffracted light which is heretofore generated in the backward path is thus eliminated.

Title: Coating method
Inventor: TAGUCHI KAZUHISA
IPC: B05D1/26
Filed: 1980-12-15
Abstract: PURPOSE: To enable applying highly viscous paint liquid which does not form beads, when the highly viscous paint liquid is applied to the surface of a beltlike support with use of a slide hopper, by feeding bead-forming paint liquid under the layer of the highly viscous paint liquid.  
     CONSTITUTION: Paint liquid 5 having a viscosity of about 100W1,000 centipoise is applied to a beltlike support 3 such as paper or a baryta paper, etc. being transfered along a direction shown by an arrow by a coating roll 1, at a wet coating rate of 20W100g/m 2  with use of a slide hopper-type coating head 2. Since the highly viscous paint liquid 5 does not form beads at the coating part, another paint liquid 6 having a viscosity of about 1W5 centipoise is fed as an under layer at a rate of 5W30g/m 2  to form beads and applied to the bead-forming part 4 under a reduced pressure. The highly viscous paint liquid 5 forms stable beads in company with the other paint liquid 6. As a result, a paint film having a uniform thickness can be formed on the support 3.
