Title: Preparation of plastic hollow body
Inventor: NAGAI SUMIO
IPC: B29C49/04
Filed: 1989-04-28
Abstract: PURPOSE:To prevent the deformation of a product with the elapse of time caused by the strain in a wall by a method wherein split molds are held to temp. such that a hollow body generates no deformation at environmental temp. and also held to temp. such that the cooling speed of the surface on the contact side with the split molds of a parison and that of the surface on the contact side with a pressure fluid of said parison becomes equilibrium. CONSTITUTION:In blow molding, split molds 1, 1 are held to temp. wherein a hollow body generates no deformation by a change of environmental temp. and the pressure fluid (usually, the open air) blown in a parison 5 is held to temp. wherein the cooling speed on the contact side with the split molds 1, 1 of the parison 5 and that on the contact side with the pressure fluid of said parison 5 becomes equilibrium. That is, the temp. of the split molds 1, 1 is held to a range of 25 - 45 deg.C and that of the pressure fluid is made lower than the temp. of the split molds 1, 1 to be held so as to have temp. difference of 5 - 40 deg.C. By holding the temp. of the split molds 1, 1 and that of the pressure fluid, even when a change of environmental temp. is generated during keeping after molding, no deformation is generated in a molded product and no strain is also generated in the wall of the parison 5 in the cooling process of the parison. Therefore, the deformation of the molded product with the elapse of time caused by the strain in the wall thereof is not generated.

Title: Method for navigating vehicle
Inventor: SUGIYAMA HIROYUKI
IPC: G09B29/00
Filed: 1992-04-04
Abstract: PURPOSE:To provide certainty and correctness by performing a relative-mode position-detecting process, and, if it is difficult to estimate a reliable position, switching the process to an absolute-position detecting process, and performing that relative-mode position-detecting process which corresponds to the absolute mode. CONSTITUTION:The system comprises a base station, a support station, a key station, a vehicle station and a storage medium. The vehicle station has a position detecting device and a road-information storage medium, etc. An area is detected by the position detecting device and specified according to its latitude and longitude, and a relative mode is started by an index from the number of the area, and navigation is carried out in the relative mode according to data on travel. Guidance from the key station is also processed in the relative mode and routes are displayed in sequence by the painting out of the corresponding nodes. An absolute-mode position detecting process is carried out as navigation is carried out in the relative mode, and in the case of the shift into a movable area which is not recorded on the storage medium for map information and the like, it is announced and the displaying of routes in the relative mode is switched to that in the absolute mode.

Title: Electrostatic induction-type semiconductor logical circuit
Inventor: HORIBA YASUTAKA
IPC: H03K19/094
Filed: 1977-09-13
Abstract: PURPOSE:To make an operation characteristic high-speed by making the connection resistance of FET small and making accumulated electric charge small. CONSTITUTION:N<-> type layer 2 is grown epitaxially on N<+> type semiconductor substrate 1, and P type impurity ions are injected throughout the surface. At this time the P type impurity injection quantity to akirt area 2a where epi-layer 2 contacts with substrate 1 is made equal to the N type impurity quantity in area 2a, and the effective impurity concentration is made very low so that surface layer 2b of epi-layer 2 may be N<--> type, and the thickness of layer 2b is made thin. After that, P type injector area 3 and P type gate area 4 are formed from N<--> type layer 2b across N type layer 2a by diffusion, and channel area 6 is generated between areas 4. After that, shallow N<+> type gate area 5 is formed in area 6 by diffusion to fit electrode 9, and electrode 7 is formed in area 3. Thus, since the area which has a very low impurity concentration and is shallow is provided in the channel area, high-speed operation characteristic can be obtained.

Title: Fastening device
Inventor: WRIGLEY ANDREW NICHOLSON
IPC: F16B13/00
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To support a heavy load with a relatively low cost by providing a toggle bar connected to a shank of a fastener so that it can be broken. SOLUTION: In this device 1, when a head 3 is inserted into a member 8 to a position to be in contact with a surface 7 of the member 8 by means of cutting edges 14, 15, a fixation screw 24 is inserted into a passage 25 of a shank 2. When the screw 24 is led into the device 1, a tip of the screw 24 abuts on a slant face 27 of a toggle bar 5 so that an end of the toggle bar 5 is pressed to the radial outer side of the shank 2, thereby braking fragile connection parts 20, 21 or the like. As a result, the bar 5 rotates at the angle of 90 deg. to move to an acting position. At this moment, a protrusion acts as a turning point to a face 30. When it comes to the acting position, the serew 24 comes to a position on a substantially straight line with a through hole 23 of the bar 5.  Then, when the screw 24 is rotated, it advances while forming an internal thread on the surface of the through hole 23, and the bar 5 is pulled to the head 3. Accordingly, another member 35 is fixed to the surface 7 of the member 8 finally.

Abstract: PURPOSE:To prevent deterioration of a sensor from progressing due to heating by actuating a burner simultaneously with the initiation of burning of the burner when the burning of the burner is started before the lapse of set time after interruption of the burning. CONSTITUTION:Failure decision means 103 is adapted to be actuated after the lapse of set time after the initiation of combustion of a burner 2 so that it does not judge a temporal incomplete combustion state just after the intiation of the combustion to be a failure.

The heating control means 104 starts heating simultaneously with the initiation of the combustion of the burner 2 and interrupts the burning after set time elapsed from the interruption of the combustion. In the control unit H failure decision means 105 is constructed which judges the CO sensor S to be in failure when the CO sensor S does not detect a non-combustion component of set concentration or more before 60 seconds, for example, elapsed after the initiation of the combustion.

Abstract: PROBLEM TO BE SOLVED: To obtain an ultrasonic motor which is manufactured without labor, whose performance degradation can be prevented and whose polarization does not require a high voltage. SOLUTION: The stator of this ultrasonic motor is constituted, in such a way that semicylindrical elastic bodies are installed on both faces of two laminated sheet-like piezoelectric elements. On the surface of the first piezoelectric element 21, electrodes 41 are divided and formed into 'a cross inside a square' shapes, and their polarization states are alternate. Likewise, on the rear of the second piezoelectric element 22, electrodes 42 are divided and formed into 'a cross inside a square' shapes, and their polarization direction is opposite to the polarization direction of the first opposite piezoelectric element 21.

In addition, a metal plate 5 is interposed between the first piezoelectric element 21 and the second piezoelectric element 22, and the electrodes 43, 44 are led out to the outside. When a frequency voltage is applied to the piezoelectric elements 21, 22, end edges in the longitudinal direction are bent and vibrated in mutually opposite directions, their bending vibration is transmitted to the elastic bodies, and torsional vibration is generated in the stator.
