Title: Gear peening processing method and device
Inventor: MIYAZAKI MANABU
IPC: B24C1/10
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To improve the fatigue strength of a deddendum area by letting the addendum of a gear interfer with a interference material, by hitting a peening body at the deddendum area with a tensile stress generated in the deddendum area of the gear, and implementing the shot peening. SOLUTION: A gear 2 is attached to a rotatable spindle 3 and an interference material 4 is so arranged as to interfere with an addendum of the gear 2. The rotation of the spindle 3 rotates the gear 2 to let the addendum of the gear 2 interfere with the interference material 4. This constitution allows the shot peening by hitting a peening body 7 at the deddendum so as to prevent the fracture in the deddendum area of the gear. Even if the peening body moves at low speed, the tensile force is applied thereon so that the fatigue strength can be improved. The deformation of the tooth shape of the gear can be suppressed to the minimum.

Title: External noise detecting circuit of automatic sound volume controller
Inventor: TAKIZAWA TETSUYA
IPC: H03G3/32
Filed: 1981-08-06
Abstract: PURPOSE:To detect an external noise component accurately even when a speaker and a microphone are specially close to each other, by providing a rectifying circuit which rectifies the output of a narrow-band amplifier and a subtracting circuit which processes the output of the rectifying circuit by subtraction. CONSTITUTION:The output of a microphone 7 is delayed behind the input signal to a speaker 4 by the time which corresponds to the distance between the speaker 4 and microphone 7, but the distance is extremely short and the delay time is several mS and below, so a time difference and a phase shift due to the delay are absorbed by giving adequate time constant to rectifying circuits 25 and 26. Therefore, variation in rectification output with time is nearly equalized with ease. Consequently, the output of a substracting circuit 27 for processing those rectification outputs by subtraction is nearly zero and an acoustic signal component inputted from the speaker 4 to the microphone 7 is nearly erased, thereby detecting only external noise components passed through narrow- band amplifiers 15-17.

Title: Brake-fluid pressure control system
Inventor: TAKESHITA HIROSHI
IPC: B60T8/28
Filed: 1977-10-13
Abstract: PURPOSE: To prevent wheel lock and provide sufficient braking power by suspending for a given length of time the supply of fluid pressure to rear wheel brakes when unloaded prior to reversion to master pressure and by proportioning fluid pressure level for rear wheel brakes to the master pressure level.  
     CONSTITUTION: When braking is applied to an unloaded vehicle, there occurs a proportionate rise in master cylinder pressure Pm and in rear wheel cylinder pressure Pw, but deceleration of a vehicle to a predetermined speed rotates a ball 18, disengages from a cut valve means 16 and closes a valve 16b, thereby shutting off the supply of fluid pressure to rear wheel brakes. Continuous increase in master pressure would move a stepped piston 21 leftward, lifting a valve 16b off its seat and allowing master pressure to be applied to the rear wheel cylinder. As the master pressure slowing down a vehicle to a given speed is raised to a higher level when the vehicle is loaded than when unloaded, sufficient braking power is obtained by operation of a piston 21 which keeps the cut valve means 16 open
