Title: Amplification circuit
Inventor: MUNAKATA ICHIRO
IPC: H03G3/30
Filed: 1994-09-14
Abstract: PURPOSE: To quickly operate the AGC amplification circuit which keeps the average voltage level of the output signal constant in the stable state regardless of switching of the input signal or the like. CONSTITUTION: While an input signal Vi is in the signal absence state, an output signal Vo is approximately 0V, and a clamp signal VCL, outputted from a clamp circuit 20 is equal to a clamp voltage E3 . When the input signal Vi goes to the signal presence state, a variable amplification circuit 10 is operated with a maximum amplification factor, and a detection voltage Vd rises to about a reference voltage E2 in a short time. The variable amplification circuit 10 amplifies the input signal with an amplification factor corresponding to the voltage value of the clamp signal VCL; and when the clamp signal VCL is stabilized, the average voltage level of the output signal Vo is approximately equal to the reference signal E2 .

Title: Horn switch device for vehicle
Inventor: NARITA HISASHI
IPC: B62D1/04
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To prevent the cutting off of the conductivity between a horn contact and a slip ring in spite of a long use of a horn switch device for vehicles. SOLUTION: The horn switch device comprises a caulking section 20a formed at the tip of a horn contact body 20 comprising iron members, and a contact section 21 comprising brass members fixed to the caulking section 20a by caulking. The contact section 21 contacts a slip ring 18 comprising iron members, allowing a horn contact 16 and the slip ring 18 to become conductive. When the contact section 21 is worn due to a long use, the caulking section 20a of the horn contact body 20 is brought into contact with the slip ring 18. Since at this moment, iron members rub against each other according to the turning operation of a steering wheel 4, chattering sound is made by the caulking section 20a, calling driver's attention to the fact of wearing.

IPC: G11B7/257
Filed: 1988-09-05
Abstract: PURPOSE:To prevent the deterioration of a recording layer by pitting corrosion and to obtain the optical recording medium having excellent long-term reliability by forming a protective layer consisting of the electron-ray cued and crosslinked matter of a bisphenol A type epoxy resin compsn. CONSTITUTION:The electron-ray curing type compd. which is heretofore used as the protective layer of the optical recording medium of the conventional embodiment is an acrylate resin compsn. Although this compd. has a protective effect to the flaws and stains from the outside, a sufficient crosslinking density is not obtainable with the cured layer consisting of this acrylate resin compsn. and the layer does not have the sufficient protective power to permeation of water. The protective layer formed by curing and crosslinking the bisphenol A type epoxy resin compsn. which has excellent moistureproofness as the electron-ray curing type compd. is, thereupon, provided, by which the protective layer having the sufficiently high crosslinking density and the excellent moistureproof effect is formed.

Title: Variable capacity type piston machine and operation method therefor
Inventor: OCHIAI TAKASHI
IPC: F03C1/38
Filed: 1989-08-28
Abstract: PURPOSE:To control the tones of noises independent of the number of rotation to enable treatment to offset the noises from an audible zone by providing an electromagnetic valve at the passage between a chamber disposed on the way of a passage and a discharge port. CONSTITUTION:The changes of pressure is produced at a discharge port 3 side corresponding to the opening and closing of an electromagnetic valve 6 between a chamber 5 and the discharge port 3. The frequency of the change of the pressure is not related to the number of revolution of a pump, but is related to the frequency of opening/ closing of the electromagnetic valve 6. Consequently, the frequency of opening/closing of the electromagnetic valve 6 is properly adjusted to change the frequency of the pressure changes of the discharge port 3 to change the tones of noises produced to less offensive sound to the ear independent of the revolutional number of a cylinder block, or to enable treatment to offset them from an audible zone. The frequency of opening/closing of the electromagnetic valve 6 is properly adjusted to be able to offset the frequency of the pressure changes in a cylinder and the discharge port to a frequency which resonates with a variable capacity type piston pump and pipes connected thereto.

As a result, the pin 8 is made to protrude furthest, and its tip is brought into contact with the ground and a powerful grip is obtained. Meanwhile, when the need of using the device 1 is gone, the pin 8 is housed into the device main body by rotating the body 13 in an arrow B direction.

Title: Piezoelectric oscillator
Inventor: OKUYAMA HIROTARO
IPC: B06B1/06
Filed: 1984-10-20
Abstract: PURPOSE:To reduce the diametric oscillation mode or the transverse oscillation mode and its harmonic oscillation mode to reduce spurious components by sticking a load medium of large acoustic loss to the outside peripheral edge of a piezoelectric ceramic element body. CONSTITUTION:A load medium 4 of large acoustic loss is stuck to the outside peripheral edge of a piezoelectric ceramic element body 1, and many through holes 5 are formed in the thickness direction of the piezoelectric ceramic element body. Since a characteristic similar to anisotropy is given to the oscillator without reducing the dielectric constant by providing these through holes 5, the diametric oscillation mode or the transverse oscillation mode is reduced furthermore by the action of the load medium 4 of large acoustic loss to reduce spurious components. If through holes 5 are so formed that their maximum diameter l is smaller than a wavelength lambda of the acoustic wave in an acoustic medium due to a resonance frequency f0, the acoustic load is heavier apparently. Thus, when the oscillator is driven by pulses in case of radiation of ultrasonic waves into water, a mechanical quality coefficient Qm in water is smaller than that of a conventional piezoelectric oscillator, and the ultrasonic pulse width is shorter to improve the distance resolution.
