Inventor: YOSHINO HIDENORI
IPC: G01V8/20
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a detection device of a carried object that can improve a repetition accuracy and can be mounted inexpensively. SOLUTION: A detection device of a carried object is provided with a partition plate 1a at a position that passes the diameter of the tip part of an outer cylinder 1e and divides the tip part of the outer cylinder 1e into two portions. A plurality of light projection side fibers 2a are inserted into one of the tip part of the outer cylinder 1e and a plurality of light reception side fibers 32a are inserted into the other, thus constituting a separation-type fiber sensor 1 where a light projection part 2 and a light reception part 3 are separated. Also, by providing the partition plate 1a vertically in the transpiration direction of a lead frame 31 as a carried object, a detection range Z that is narrow in a carrying direction and is wide in the width wise direction of the lead frame 31 can be obtained. More specifically, a range where the detection position in the carrying direction scatters becomes narrow, thus accurately and securely detecting the carried object.

Title: Rotary drive controller of recorded disk
Inventor: NAITOU RIYUUICHI
IPC: G11B19/24
Filed: 1980-09-08
Abstract: PURPOSE: To ensure the accurate driving of a disk in a constant linear speed and with simple constitution, by controlling the rotation of the disk so that the linear speed is proportional to the reference current voltage.  
     CONSTITUTION: A frequency signal generator 2 produces M pieces of pulses per rotation of a disk 1, and a monostable multivibrator 3 receives these pulses to produce a gate pulse of a fixed time T for each pulse. Accordingly, the output waveform C of a gate 6 is turned into the output voltage E of a potentiometer 5 for time T during a period (t) and then into an waveform of O in other periods of time. As a result, the mean voltage E 3  of the output (d) of an LPF7 is equal to E 2 × T/t. The difference between the voltage E 3  and the reference DC voltage E r  is obtained by a differential amplifier 8 and then amplified by a driving circuit 9 to drive a DC motor 10. With the rotation of the motor 10, the number of revolutions per second is decided for the disk 1. Thus the linear speed of the disk 1 is proportional to the voltage E r , and the disk 1 can be turned in a constant linear speed regardless of the radius (r) of the disk 1.

Title: Circuit for compensating phase difference between intraaline clock signal added to pcmmtime sharing multilines connected to pcmmexchange and local clock signal of exchange
Inventor: RORUFU TSUAITOREEKU
IPC: H04J3/06
Filed: 1980-09-10
Abstract: A pulse coded time division multiplex (PCM) telecommunication system has two non-synchronous clock pulse trains for controlling information transfer and switching operations, respectively. In a circuit arrangement for compensating phase differences resulting from deviations between both clock pulse trains there is arranged an intermediate store for externally controlled buffering of PCM words for half of a pulse frame and connected thereto a buffer store for internally controlled buffering of PCM words for a full pulse frame. The intermediate store is designed for two modes of operation under control of the external clock pulse train. In an active mode during one cycle at first a stored PCM word is read out and is then replaced by a new PCM word. In the second mode the same PCM word first is temporarily buffered and immediately read out thereafter. Change of operation is controlled by a control unit monitoring addresses for alternate read operations and write operations of the buffer store of a minimum off-set of selected addresses to obtain by skipping of half of a pulse frame sufficient off-set without continuous uncontrolled slippage losses.

Filed: 1994-06-07
Abstract: PURPOSE:To improve precision of a stop position of a film like member, and restrict sliding noise in motion of the film like member by setting tension applied to the film like member constantly within a specified range. CONSTITUTION:A pulley 22 is rotatably connected to a follower shaft 16 through a connection shaft 23, and its rotation range is regulated to be between a position where one standing part 27b is applied to a pin part 23e of the connection shaft 23, and a position where the other standing part 27c is applied to the pin part 23e. In the condition where a film door 19 and a wire 24 are assembled, tension applied on a wire 24 balances with spring force of a torsion coil spring 25, and tension of 25Nmm or more and 80Nmm or less is applied to the follower shaft 16 in such a direction as to stretch the film door 19. In the case where excessive tension is applied to the wire 24, the pulley 22 is rotated, and the standing part 27c and the pin part 23e abut on each other, so further rotation is restricted. Deflection of a stop position of the filmlike member or its sliding noise can thus be set under tolerable values.
