Abstract: PURPOSE: To raise wear resistance as well as obtain adequate softness and toughness by forming a hardened layer denatured by heating on the sliding portion of a holder for plastic roller bearings.  
     CONSTITUTION: The holder 4 for roller bearings, consisting of the outer ring 1, the ball 2, and the inner ring 3, is formed of a plastic material, preferably of a polyamideimide resin, and the hardened layer 43 is formed at depths d 1  and d 2  from the surfaces of the inside circumference 411, the outside circumference 412, and both sides 413, at depth d 2  from the surface of the pocket portion 421 on both sides, and at depth d 3  on the adjacent pocket side 42. The hardened layer 43 is formed by modifying (increasing molecular weight) the resin by heating it at an appropriate temperature in such a way that the heating temperature is raised at a proper rate with time in a furnace after molding the holder 4. Thus, the inside texture 44 having proper softness and toughness can be formed in its inside.

IPC: H04B1/707
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a synchronization device with ease of a hardware configuration in which synchronization capture and locking are attained allowing a receiver side of a spread spectrum communication system to control a data clock based on a data rate level. SOLUTION: A signal sent from a transmitter side is subjected to differential decoding and the result is given to a DMF 31 as input data. The DMF 31 acquires a correlation value and provides an output of the correlation value and data value to a maximum value detection section 32. The maximum value detection section 32 extracts a maximum correlation value among those outputted matching a sampling timing and provides an output of a position at which the maximum correlation value is in existence (synchronizing point signal) and data value corresponding to the maximum correlation value. A synchronizing point comparison section 33 monitors the synchronizing point signal to detect whether or not the synchronizing point is moved and to reset a counter based on the movement of the synchronizing point. Furthermore, A counter reset discrimination section 34 monitors the synchronizing point signal and resets a counter 35 so that an apparent position of the synchronizing point comes just around the middle of a window when the count representing the synchronizing point is not within a prescribed range.

IPC: G03B21/00
Filed: 1987-04-09
Abstract: PURPOSE:To maintain the illuminance of a screen constant by providing a distance detector measuring a distance from a projector main body to the screen. CONSTITUTION:The oscillator 10 of the distance detector 1 oscillates by the inherent resonance frequency of a wave transmitter 14. A signal (b) that a gate circuit 11 gates with the aid of the trigger signal (a) of a trigger generator 12 is amplified and transmitted as an ultrasonic wave by the wave transmitter 14 to the screen 4. The transmitted ultrasonic wave is reflected by the screen 4. The signal detected by a wave receiver 15 generates a time difference, depending upon the distance to the screen 4. After the signal passes through the wave receiver 15, a detector 16 and a waveform shaping circuit 17, a signal (d) is obtained. On the other hand, with the aid of the previously obtained signal (d), a triangle wave generator 18 sample-holds an obtained signal (e) that the output signal of the trigger generator 12 has reset, and obtains an output voltage in proportion to the time delayed from a trigger (a) pulse, i.e. in proportion to the distance. Thus the appropriate screen illuminance can be automatically maintained.
