Title: Frame synchronizing method and device
Inventor: NAKAI TAKAO
IPC: H04L7/08
Filed: 1991-07-30
Abstract: PURPOSE:To detect a frame synchronization bit at a higher speed by detecting a synchronization bit during forward protection and setting the backward protection state immediately after synchronizing step-out. CONSTITUTION:When a location in an input data string is dislocated, the outputs of coincidence/non-coincidence detecting circuits 13a-13n whose coincidence is detected when the synchronization is confirmed are discordant, a protective circuit 14 is set in the forward protection state and discordance exceeding the protective stage number is detected, the synchronizing stepping-out is set. In this case, in the forward protective state, a synchronization bit detection circuit detecting the synchronization bit so far among the synchronization bit detection circuits 12a-12n detects a synchronization bit, then a protective circuit 14 sends a reset pulse S6 to a pulse generating circuit 15. The circuit 15 changes the phase of a frame synchronization pulse S7 of an output of the circuit 15 to retrieve the presence of detection of the synchronization bit of the circuits 12a-12n and detects any of the circuits 12a-12n detecting the synchronization bit immediately.

Title: High voltage stabilizing circuit
Inventor: NAKANO SHIGERU
IPC: H04N3/185
Filed: 1988-07-28
Abstract: PURPOSE:To facilitate the taking-out of the signal of a high voltage fluctuation by connecting a resistance between the emitter and the ground of a horizontal output transistor and detecting the high voltage fluctuation as the fluctuation of the load voltage to occur at the resistance. CONSTITUTION:When a high voltage load current is increased and a high voltage HV is reduced, the collector current of a transistor TR1 connected to the primary side coil of a flyback transformer 1 is increased, the voltage drop of a resistance R0 is enlarged, the base voltage of a transistor TR2 rectified by a diode D1 and a capacitor C0 is increased and a transistor TR2 is conducted. Since a transistor TR3 is turned off, the combined capacity of capacitors C3 and C4 is formed, and made smaller than the combined capacity of C3-C5 when the transistor TR3 is turned on, the horizontal flyback period is made shorter for the part and the reduced high voltage is corrected to an original value. On the contrary, when a high voltage load current is decreased, the flyback period is longer and the action is executed in the direction to lower the high voltage. Thus, the signal of the fluctuation of a high voltage HV can be easily taken out.

Title: Optical displacement gauge
Inventor: KUWABARA YOSHIHARU
IPC: G01C3/06
Filed: 1993-07-30
Abstract: PURPOSE:To maintain stability during a motion at high speed and acceleration by keeping the center of gravity of a whole moving section including a focusing lens, on the line of force of a drive system. CONSTITUTION:A moving section 40 has an approximately rectangular frame 41 and a focusing lens 20 is fixed to the lower end thereof. In addition, the section 40 is held, so as to be freely movable along a displacement measurement direction with a pair of parallel leaf springs 60, relative to a displacement gauge body 8. The center of gravity G of the whole of the section 40 is virtually positioned on the line of force WL of a drive system formed out of a drive coil 62 and a magnet 64 as a pair. According to this construction, an actuator when driven at high acceleration, is not dislocated due to moment around the center of gravity G of the moving section 40. The actuator can thus be controlled with high accuracy at the time of measuring a measurement object under displacement at high speed. Furthermore, the optical axis OA of the lens 20 is kept within a plane including the flexed section of the parallel leaf springs 60 at the side of the moving section 40, thereby enabling the dislocation of the lens 20 from the optical axis OA due to disturbances, to be kept approximately at zero.

Title: Friction material for car
Inventor: IMAO MAKOTO
IPC: F16D69/02
Filed: 1982-10-28
Abstract: PURPOSE:To prevent occurrence of fracture in a friction material by providing peripheral surfaces of a plate-shaped friction material with a layer containing high-strength bonding agent, thereby preventing rust generated from the peripheral part and concurrently reinforcing the peripheral part. CONSTITUTION:To fabricate this friction material for a car, a mixed material is fabricated first by thoroughly mixing both bonding material powder consisting of steel wool and phenol resin and a friction adjusting agent consisting of barium sulfate or graphite, using a Banbury mixer or a high-speed rotary machine. Then the mixed material is filled in a mould and pressed for preliminary formation to fabricate a roughly- formed mother material 2. Solution in which a bonding agent is dissolved, is applied to the peripheral surface of the roughly-formed material 2. The amount of solution applied should be about 10-75mg/cm<2>, in term of a solid-state binding agent. Next, the roughly-formed material whose peripheral surface 1 is coated with binding agent solution is placed in a heating mould, and it is heated and pressed for fusion reaction of the binding agent. Thus, a friction material formed in an integrated body can be fabricated. Accordingly, a layer 1 containing the high-strength bonding agent on the peripheral surface prevents generation of rust, and at the same time the mechanical strength of the peripheral surface is enhanced. Therefore, fracture in the friction material due to rust generation can be eliminated.
