Title: Shock absorber
Inventor: YAMAZAKI FUMIO
IPC: F16F9/10
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To show effective shock absorbing characteristics and eliminate the difficulty in adjustment of the characteristics. SOLUTION: A cylinder 2 has a part 21 having a large inner diameter 21 and a part 22 having a small inner diameter. A cylindrical piston 3 has an end wall 31 at its one end, and an outer diameter so as to enable sliding with the small inner diameter part 22. A plurality of orifices 32a are formed on a peripheral wall 32, while a through-hole 31a for a piston rod 4 and at least one through-hole 31b for viscous fluid are formed on the end wall 31. The piston rod 4 has a strokelarger than thickness of the end wall 31 of the piston 3, and is provided with flanges 43, 44 sandwiching the end wall 31 therebetween. When the piston 3 is moved in the direction of absorbing shock, the through-hole 31b on the end wall 31 is blocked by means of the flange 43. The viscous fluid is moved only by the orifices 32a.  On resetting the piston 3, the through-hole 31b is released, and a large amount of viscous fluid is moved.

Title: Radio equipment
Inventor: YAJIMA KOTARO
IPC: H04B1/3822
Filed: 1987-03-25
Abstract: PURPOSE:To simlify the circuitry and to sufficiently modulate the oscillation frequency for transmission by modulating a low frequency signal by the second local oscillator of a receiver. CONSTITUTION:The frequency that is modulated in a first local oscillation part is made an oscillation frequency for transmission, and the same signal as that in said oscillation part but inverse in its phase is modulated in the second local oscillation part. A signal modulated in the first local oscillation part is frequency-converted in a first frequency conversion part, and amplified together with a received signal in a first intermediate frequency amplification part, then inputted to a second frequency conversion part. The signal is mixed with the modulated wave phase is inversed from the second local oscillation part in the second frequency conversion part, where the modulated signal is offset, however, the received signal is frequency-converted and then transmitted to the second intermediate frequency amplifier. In such a way, a signal to be detected is made only the received signal, hence the leaking of a modulated wave on the transmission-side can be suppressed.

Title: Detecting device for asleeping drive
Inventor: SEKO TAKATOSHI
IPC: B62D1/00
Filed: 1979-06-11
Abstract: PURPOSE: To perform a positive detecting of a decreased awakening by a method wherein a decreased awakening is judged in response to a steering operation signal for detecting a variation in steering operation and a response signal for detecting or judging a responsing time of a driver against a preliminary alarm.  
     CONSTITUTION: When a variation of the steering operation signal per unit time is exceeded over the predetermined setting value, the first detecting ciruit 1 produces a signal indicating a substantial variation in the steering operation at the time setting circuit 12. The time setting circuit 12 keeps on-condition for a certain time, and then the preliminary alarm generating circuit 11 generates the preliminary alarm for showing a sight, a hearing and a skin sensing to ask the driver to act against the alarm. When the driver operates in response to the alarm to operate the response operation circuit 13, a response time is judged in the decision making circuit if the responding time is exceeded over the set time or not. In case of exceeded time of setting value, a decreased awakening signal is fed to a counter circuit 20, and when the number is reached up to a desired value, the alarm circuit 30 is operated.

Title: Vibration-proof device
Inventor: ORIKAWA MICHIHIRO
IPC: F16F13/00
Filed: 1992-02-25
Abstract: PURPOSE:To remove the residual chemical treatment liquid at the time of valcanization by welding a conical metal piece to a fitting metal piece on one side, achieving the vulcanizing adhesion of an elastic rubber body between the conical surface and the fitting metal piece on the other side, and forming a through hole connecting to the outside to the conical void space formed by the respective metal pieces. CONSTITUTION:Before the vulcanizing adhesion of an elastic rubber body and a metal piece is achieved, four through holes 20 are preliminarily formed at the interval of 90 deg. in the conical part of a conical metal pieces 5, and in addition, a through hole 20 is formed in the truncated conical part. Thus, when the fitting metal pieces 1 and the conical metal pieces 5 are welded together and immersed in the chemical treatment liquid, the treatment liquid freely enters the void space, and flows out when the pieces are lifted out of the treatment liquid. Thus, no treatment liquid entered the void space exists when the vulcanizing adhesion is achieved, leaving no adverse effects such as defective adhesion caused by the treatment liquid. Thus, it is unnecessary that the welding between the fitting metal piece 1 and the conical metal piece 5 should be perfectly airtight, and the spot welding or the like may be sufficiently acceptable so long as only the strength is secured. And the full checking of the weldings becomes unnecessary.

Filed: 1981-05-18
Abstract: PURPOSE:To keep a fluidizing state constant, by detecting a pressure at the lower position of a dispersing plate and controlling a flow rate adjusting valve with feedback so that this pressure detecting value can be a constant value. CONSTITUTION:A pressure P at the lower position of a dispersing plate 2 can be regarded as the sum of a pressure loss  P1 caused by powder and granules 5 and a pressure loss  P2 caused by a dispersing plate 2, when the pressure at the upper part of a tank 1 is an atmospheric pressure. The pressure loss  P1 is always constant when the powder 5 is in a fluidizing state. F'= P2.S= muAA'V/ X' is obtained, where A' is the sum of surface areas of a vent hole of the plate  2, X' is an average clearance of the vent hole, F' is a force exerted on the plate 2, S is the area of the plate, V1 is the velocity of a gas, and mu is the viscosity of the gas, and when the relation of muS is constant, the  P2 is constant. Thus, the flow rate adjusting valve can be controlled with feedback so that the prssure value of the lower position of the dispersing pate can be constant.

Therefore light emitted from the LED is efficiently guided from the guide part to the member and the member is brightly emitted. Since the member forms the projected part on the surface exposed to the front face of the doorphone slave equipment 1, light is brightly concentrated and the visibility of the member looked from the side can be improved. At the time of abnormality, the window 3 is flickered as an alarm display lamp.
