IPC: F16F15/134
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To suppress the circumferential clearance of a stopper mechanism in a damper mechanism which realizes characteristics of high stiffness in a large twist angle range while realizing low stiffness in a small twist angle range. SOLUTION: This damper mechanism 4 is equipped with an output rotary hub 110, an input rotor 2, a hub flange 12, a first spring 9, a second spring 10, a second stopper 17 and a compression part 18, The first spring 9 and the second spring 10 are arranged in tandem across the hub flange 12 between the rotating directions of the output rotary hub 110 and the input rotor 2. In an initial state, the second spring 10 is retained under a condition that it is compressed in the rotating direction between the hub flange 12 and the input rotor 2. When a twist angle reaches a first twist angle, the second stopper 17 stops relative rotation of the output rotary hub 110 and the hub flange 12. When the twist angle reaches a second twist angle, the compression part 18 starts to compress the first spring 9.

IPC: C22C1/00
Filed: 1981-10-19
Abstract: PURPOSE:To obtain a high permeability alloy thin strip by extremely easy processing such as machine punching by employing a molten metal rapidly cooling  method, by adding Ti, Zr, V, Nb and Ta to an Fe-Si-Al high permeability alloy  in a proper amount.

Title: Taper etching
Inventor: MASUDA YOJI
IPC: H01L21/302
Filed: 1987-07-03
Abstract: PURPOSE:To enable the changing of a tapered angle of a layer to be etched by the use of intensity of ultraviolet rays, by radiating ultraviolet rays when high-frequency discharge is used in a mixed gas containing an oxygen gas and an etching gas so that a resist layer and the layer to be etched are etched at the same time. CONSTITUTION:A silicon oxidizing film with phosphorus added as an impurity 12 (abbreviated below in PSG) is formed as a layer to be etched on a silicon substrate 11, and a resist layer 13 of a contact pattern is formed on the layer 12. A low-pressure mercury lamp is used as an ultraviolet light source, and a mixed gas consisting of O2, CHF3, He is used as an etching gas. Next, intensity of radiated ultraviolet rays is reduced to perform high-frequency discharge, and the PSG film 12 is dry-etched nearly half in its depth. The intensity of the ultraviolet rays is enlarged without interrupting the high-frequency discharge, so that the PSG film 12 is etched to the silicon substrate 11 in depth. Since the intensity of the ultraviolet rays is high and the quantity of oxygen radicals is large then, an etching speed of the resist layer 13 is increased to enlarge a tapered angle. Subsequently the resist layer 13 is removed and an Al wiring 14 is piled, so that contact can be manufactured with a good burial state of the Al wiring 14.

Title: Controlling device of laser frequency
Inventor: KASHIWARA HIROBUMI
IPC: H01S3/139
Filed: 1980-11-26
Abstract: PURPOSE:To stabilize the oscillation frequency of a laser light by a method wherein a laser beam for transmission is heterodyne detected and passed through a band path filter (BPF), and a voltage according to the deviation of the intermediate frequency (IF) of an L0 (local oscillator) laser which corresponds to a fixed output from the center frequency of the BPF is generated and feedbacked to a piezo element. CONSTITUTION:Laser beams 1 for transmission and 2 for L0 are heterodyne detected at 3 and amplified at 4, and then passed through BPF5. The output Vt is compared with the reference voltage 25, and when it is at a fixed level (c), the input voltage 22 to a circuit 30 is changed to H, and the output voltage VR of a terminal 21 correspondingly becomes a fixed value, and the output voltage Vt of a demodulator 6 is fixed at a point Q in a curve (d). The output of terminal 23 turns to H, so a contact 15 is closed. Thus, a fixed offset voltage 20 is added to the output of a 1kHz oscillator 14 at 16 and amplified at 17 and 18, and then fed to a piezo electric element 19 which is directly connected with the L0 laser 2. Vt is phase detected at 8 referring to the output of the oscillator 14 and integrated at 9 to obtain a D.C. deviation voltage DELTAV. This voltage is amplified at 10 and added to VR at 11, and fed to a piezo electric device 13 to correct the oscillation frequency of the transmission laser to a fixed value, obtaining a pulsed laser beam with a stable frequency.

Title: Charger for magnetic levitation carrier
Inventor: NAMIKATA TOSHIO
IPC: H02J7/00
Filed: 1989-06-29
Abstract: PURPOSE:To charge a plurality of secondary cells independently in a short time by automatically detecting connection of charging power source then disconnecting every secondary cell unit and connecting every cell unit with a charging power source. CONSTITUTION:When a charger is not connected, contacts 33a-33d are opened while a contact 33g is closed. Cells 18a, 18b are connected in series and the electrode voltage at the opposite ends is outputted to an output connector 32. When a charger is connected between terminals 34a, 34b, a relay 33 detects the connection then the contacts 33a-33d are entirely closed while the contact 33g is opened. Consequently, the cells 18a, 18b are switched to parallel connection and thereby respective cells 18a, 18b are set ready to be independently charged through a charging connector 34. By such arrangement, each cell can be charged independently only through switching of a switch which responds to connection of the charger without requiring modification of wiring.

Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To easily reproduce decoding with an initial coding state or to repro duce the initial coding state by making a code of an addition value for normali zation information with a number using several bits of a two-dimensional block selectable. SOLUTION: A normalization information adjustment circuit 911 outputs a numerical value for performing level adjustment of a unit block by adding it to the normalization information. An adder 909 adds the numerical value from the normalization information adjustment circuit 911 to the scale factor value of the unit block. When the numerical value outputted from the normalization information adjustment circuit 911 is negative, the adder 909 acts as a subtracter. That is, similarly to a case of coding, the level adjustment of a whole band 2dB each is made possible only by that all the same numerical values outputted from the normalization information adjustment circuit 911 are added, and a so-called filter effect is obtained only by that different numerical values are added at every unit block.
