Title: Pneumatic tyre
Inventor: SAEKI MITSUTOSHI
IPC: B60C11/04
Filed: 1987-11-24
Abstract: PURPOSE:To improve linear running and drainage on a road surface in which rain grooves are formed, by a method wherein straight grooves are formed laterally symmetrically about a virtual line circumferentially drawn at the given section of a tread and inclined at a given angle with the virtual line so that a projected wedge shape is formed in a rotation direction. CONSTITUTION:A virtual line (t) is circumferentially drawn at a central area having a width being approximate 1/3 an earthing width W of a tread, and straight grooves 1, 1', 2, 2'... are formed laterally symmetrically about the virtual line. The straight grooves 1, 1', 2, 2'... are inclined at an angle of 1-15 deg.C with the circumferential direction of a tyre, and is formed in a projected wedge shape in the rotation direction of the tyre. This constitution enables improvement of linear running and drainage on a road surface in which rain grooves are formed.

Title: Ringing choke converter
Inventor: SATO MORIO
IPC: H02M3/338
Filed: 1994-10-20
Abstract: PURPOSE: To prevent the oscillation period of a transformer from becoming shorter so as to stabilize the oscillation of the transformer when a load current becomes small by exciting the transformer in the direction opposite to the exciting direction of a primary current. CONSTITUTION: A MOSFET 14 is connected in parallel with the diode 12 of a secondary-side rectifier circuit and an auxiliary winding 11c is wound around a transformer 11 so as to drive the MOSFET 14 with the voltage generated across the winding 11c. While the voltage generated across the winding 11c stays at the threshold voltage of the MOSFET 14, the MOSFET 14 is conducted and a inverse current which flows through the MOSFET 14 flows through the winding 11b successively to a forward current which flows through the diode 12. Consequently, the voltage at a capacitor 13 is nearly fixed to the voltage which is obtained by multiplying the turn ratio between a secondary winding 11b and the auxiliary winding 11c by the threshold voltage of the MOSFET 14.  Therefore, the oscillation period of a transformer can be prevented from becoming shorter and the oscillation of the transformer can be stabilized.

Title: Synthesizer tuner
Inventor: TOMITA HIROSHI
IPC: H03J5/02
Filed: 1988-11-21
Abstract: PURPOSE:To write only a desired broadcasting station in a preset memory by canceling the writing of a prescribed broadcasting station in the preset memory by operating a write canceling key when the prescribed broadcasting station is received while searching operations are made. CONSTITUTION:When an auto-preset memory operates, receivable broadcasting stations are, as a rule, successively written from preset number 1 to preset number 8 in the preset memory from the lower limit of bands. In case a receivable station is selected and a writing state is started (a writable state displaying section 12a is turned on), writing in the auto-preset memory can be canceled by pressing an up key 13a within about three seconds when a user does not want the writing judging from the channel selecting frequency displayed in a frequency displaying section 12c and preset number displaying in a preset number displaying section 12b. Therefore, the user can write a desired broadcasting station only in the preset memory even when auto-preset memory writing operations are carried on.

The result is compared with a reference voltage in a voltage judging circuit 6, and the judged signal is outputted. Meanwhile, the light of constant output is emitted from a light emitting device 11 in an optical-property inspecting part B and received with a photodetector 12. In a transmittance judging circuit 16, the reference voltage of new oil is compared with the voltage of a light detecting circuit 15, and the judged signal of the contaminated state is outputted. In a composite judging circuit 17, the above described two judged signals are combined, and the change in property is judged.

IPC: D21F3/00
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To provide a pressing outer coating for a pressing apparatus for the dehydration of a material sheet, especially the dehydration of a paper sheet in a pressing gap of a papermaking machine and provide a process for producing the pressing outer coating. SOLUTION: The objective pressing outer coating 10 has a cloth layer 18 or a belt extended between a circumferential thread 20 and a groove 12 or a blind hole starting from the surface 14 of the pressing outer coating 10 to assist an axially extended reinforcing thread 22 and a circumferential thread 20 extended on the thread 22 along the circumference of the pressing outer coating. Even if a crack is generated mainly at the bottom of the groove 12 caused by strong notch stress generated at the bottom by the intense compression pressure in operation, the propagation of crack is stopped by the continuous cloth layer 18. The life and operation reliability of the pressing outer coating are remarkably improved by this structure. Since the continuous cloth layer 18 can take the role of the circumferential thread 20, the use of the circumferential thread may be omitted in some cases.  The cloth belt 25 can be wound in the production of the coating by casting an elastomer material after the casting of a cylindrical part.

Title: Circular saw cutting machine
Inventor: SASAKI HITOSHI
IPC: B23D47/04
Filed: 1990-11-02
Abstract: PURPOSE:To control cutting time to the minimum by establishing the moving quantity of a circular saw edge according to the size and shape of a member to be cut. CONSTITUTION:In the case where a workpiece 2a is round material and has the maximum diameter, a slide-type workpiece detecting lever 10 does not touch a workpiece 2a when the workpiece 2a is clamped by a horizontal stock vice 4, but in the case where the diameter of a workpiece is small, the lever 10 strikes against the workpiece, and a circular saw l is therefore fed farther by the sliding distance of the lever 10, and by the distace (d) in the case of the minimum diameter 2e. Thus, when a limit switch 5 and a dog 6 have been established so that the stroke of the circular saw may be the necessary minimum in the case of the maximum diameter of the workpiece, the stroke required for cutting can be obtained even in the case of the small diameter of the workpiece. Even in the case of square material, the limit switch 5 and the dog 6 can be established similarly to the case of the circular material to obtain the minimum feed stroke required for the square material of the circular saw 1. Cyclic time can thereby be shortened.

Title: Guided missile
Inventor: WATANABE YOSHIKO
IPC: F42B10/14
Filed: 1987-11-24
Abstract: PURPOSE: To achieve a speedy response and a high trim angle by developing a front wing after rocket motor combustion, sending the control signal of one control device to the actuator of two kinds of steering wings, namely front and rear wings, and simultaneously steering both the wings. CONSTITUTION: When the combustion completion signal of a rocket motor is received, a development mechanism 9 of a front wing 2 operates and the front wing 2 being folded inside is developed. As a result, the force-landing point of an airframe moves to a forward Xcp2 , and a distance to a gravity position xm2 is reduced from Δx2 to Δx3 , thus improving the response of the airframe. On rotation, an actuator 6a of a front wing 2 operates in a direction for raising the front edge of the front wing 2 due to a control signal from a control device 5 and an actuator 6 of a rear wing 4 operates in a direction for lowering the front edge of a rear wing 4.  At this time, a clockwise moment required for balancing the airframe can be obtained from both of the front wing 2 and the rear wing 4, thus reducing the amount of steering of each wing as compared with a case where only one kind of steering wing is steered and hence relaxing a restriction to an elevation being generated from the stalling characteristics of wings and achieving a high trim angle.
