Title: Anti-lock brake system
Inventor: YOOZEFU PITSUKENHAAN
IPC: B60T8/00
Filed: 1989-11-24
Abstract: PURPOSE: To permit more precise brake control by adjusting at least one threshold value according to the result of measurement of the inclined position of a vehicle, in a system which reduces, maintains, or increases brake pressure if a wheel slip exceeds a predetermined threshold value. CONSTITUTION: This system measures the rotation behavior of the wheels of a vehicle such as a motorcycle and, when a decrease in the rotating speed of the wheels and/or a slip exceeds a predetermined threshold value, reduces brake pressure at the wheels with a smaller gradient than those usually employed. The system maintains or increases the brake pressure according to subsequent changes in rotation behavior of the wheels. In this case, two sensors S1 , S2 are provided in the areas of both ends of a wheel axis to make it possible to measure the distance from a road surface 12. The position of inclination is computed from the difference between the distances measured by the sensors S1 , S2 . At least one threshold value is adjusted according to the computation result to enhance braking safety on an inclined road surface.

Title: Scissors
Inventor: SAITO TATSUYA
IPC: B26B13/00
Filed: 1988-12-02
Abstract: PURPOSE:To prevent a play between both blade pieces when they are opened or closed, by a method wherein a connecting surface where connecting parts of both blades made contact apart from a recess part is so formed as to face to the recess part when overlap parts on both the blades are overlapped each other on blade-placing surfaces of handles. CONSTITUTION:A connecting arm 17 of the other blade 6 is inserted into a recess part 18 in a connecting hole 12 of the other handle 4 from an opening 12b on its side part or an opening 12a on its top end side, and then it is placed in an inclined state that an overlap part 15 of the blade 6 is apart from a blade-placing surface 9a on the handle 4. After that, the overlap part 15 of the blade 6 is overlapped on the blade-placing surface 9a, and then a fitting projecting part 11 is inserted into a fitting hole 16 on the blade 6. The connecting arm 17 of the blade 6 thus makes contact on a connecting surface 19 apart from the surface 18a of the bottom of the recess part 18. Both blade pieces 1, 2 assembled in this manner are overlapped each other at blade-overlapping parts 8 of both the handles 3, 4, and rotatively supported after a connecting projection part 13 is inserted into a connecting recess part 14. In this way, since the connecting recess and projection parts 14, 13 supporting both the blade pieces 1, 2 rotatively with each other are prevented from wearing by a friction between both the blades 5, 6, it is difficult to produce a play between them.

Abstract: PURPOSE:To eliminate the unnecessary resin flash of a mounting hole by providing the top edge of an operating pin upper than the bottom edge of sealing resin when making a through hole by permitting the fixing pin of a top die to face the operating pin of a bottom die. CONSTITUTION:When forming a mounting hole on sealing resin 1, a fixing pin 3a mounted on a top die 3 and an operating pin 4a mounted on a bottom die 4 are used, a belleville spring 4b is incorporated in the operating pin 4a and the structure permits the operating pin 4a to operate vertically. At that time, the top of the operating pin 4a is permitted to be upper than at least a resin-sealed bottom edge IC. Therefore, when the top die 3 and the bottom die 4 are clamped, the belleville spring 4b of the operating pin 4a accommodates the unevenness and the pins are adhered at the leading edge of the fixing pin 3a. Thus, the unnecessary resin flash of the mounting hole la is eliminated.

A resistance voltage dividing circuit 11, provided with a positive temperature coefficient thermistor RT1, is parallel-connected with the current-limiting resistance R1. In this current suppressing circuit, since the temperature of the positive temperature coefficient thermistor RT1 is low immediately after the application of power, the divided voltage of the resistance voltage dividing circuit 11 is low, and the triac Q1 is kept in an off state. Thereafter, the temperature of the positive temperature coefficient thermistor RT1 rises accompanying heating form the current-limiting resistance R1, and the resistance value is increased, while the divided voltage of the resistance voltage dividing circuit 11 is increased.  When the resistance value of the positive temperature coefficient thermistor RT1 reaches a certain threshold, the triac Q1 is turned on.

Title: Antifungal method of clothing dryer
Inventor: NUKINA YASUYUKI
IPC: D06F58/02
Filed: 1987-12-04
Abstract: PURPOSE: To exhibit a high microorganism removing capability by heating trichlosan to the temperature higher than the clothes temperature in a rotary drum of a clothes drying machine and introducing the vapor thereof into the rotary drum, thereby uniformly adhering the trichlosan to the clothes. CONSTITUTION: A net-like perforated body 16 made of glass fibers impregnated with the trichlosan is disposed in proximity to a heater 7. The trichlosan is heated and evaporated by the heater 7 and the vapor thereof is introduced into the rotary drum 1. The clothes to be dried are housed therein and the vaporized trichlosan diffuses down to the inside of the clothes superposed on each other and comes into contact with the clothes. The clothes are wetted and are deprived of the heat of vaporization in the process of drying and, therefore, the temperature thereof is lower than the temperature of the air which is heated by the heater 7, contains the trichlosan and is introduced into the rotary drum 1. Consequently, the trichlosan deposits and adheres to the clothes.  The uniform adhesion of the trichlosan to the clothes is thus made possible and the high microorganism removing capability is exhibited.

Filed: 1987-12-04
Abstract: PURPOSE:To dispense with the manual adjustment of the self-traveling oscillating frequency of a horizontal oscillating circuit by adding a voltage comparing circuit equipped with a reference voltage source instead of a voltage setting circuit. CONSTITUTION:A voltage comparing circuit 14 compares the voltage of a capacitor 10 and an input voltage from a reference voltage source 15, and applies a feedback to a horizontal oscillating circuit 5 so that the voltage of the capacitor 10 can be made equal to a reference voltage from the reference voltage 15. Consequently, even when the self-traveling oscillating frequency of the oscillating circuit 5 is widely deviated from a synchronizing signal frequency, by the work of the comparing circuit 14, the terminal voltage of the capacitor 10 connected to an LPF 8 is controlled at the reference voltage inputted to the comparing circuit 14, and the self-traveling oscillating frequency of the oscillating circuit 5 is made to approach the synchronizing signal frequency. Consequently, the voltage to be directly inputted from the LPF 8 to the oscillating circuit 5 is also controlled at the input voltage of the reference voltage source 15 inputted to the comparing circuit 14.
