IPC: G01B21/00
Filed: 1987-01-30
Abstract: PURPOSE:To obtain a detector of simple constitution which has extremely high restoration accuracy by employing a three-point contact structure for one of two couple of supports which support a floating lever, and controlling the rotation of the floating lever on its axis elastically. CONSTITUTION:A support couple 7 consist of a receiving seat 9 composed of three balls 18 fixed at the vertex positions of a regular triangle and a spherical body 11 which engages its recessed part and a support couple 8, on the other hand, consist of a receiving member 13 which has a V groove formed of two rollers 12 and the floating lever 3 itself. Here, the spherical body 11 is fixed to the lever 3 and engaged with the recessed part of the receiving seat 9, and the rear end 14 of the lever 3 is fitted in the V groove of a member 13 to determine the stable stationary position of the lever 13. Consequently, a housing 1 is mounted on a machine tool and moved toward a body 42 to be measured and when a detection stylus 2 contacts it, the stylus 2 is displaced so that the lever 3 moves away from the support couples 7 and 8. Then the lever 3 and the contact 25 of a switch 20 separated slightly from it contact each other to close the circuit of an LED 21, which illuminates; and the contacting of the stylus 2 is detected and its position is read to accurately detect the position of the body 42 to be measured.

Title: Corona charger
Inventor: OOTSUKA SHIYUUICHI
IPC: G03G15/02
Filed: 1982-02-15
Abstract: PURPOSE:To prevent trouble in conveying a photosensitive material, by arranging a control grid between a corona wire and a photosensitive sheet being conveyed at an open angle at the position of each of both sides of the sheet in the sheet conveying direction. CONSTITUTION:The grid wires of a grid 2 are arranged at an open angle in the conveying direction of a photosensitive sheet 4 at the position of each of both side ends, for example, all the grid wires direct at an open angle in the outside direction, or the grid wires in the middle part of the grid 2 are parallel to the conveyance direction, and the wires near the 2 side ends direct outward. Even if the forward tip of the photosensitive sheet has tendency to curve or curl, the sheet has no danger to enter a charger of such a shape as shown clearly in the figure, and the grid wires acts so as to push the sheet out of the charger by the conveyance force. Even if the sheet slips out of the conveyance direction, it does not intrude into the charger, and therefore, stable conveyance can be ensured.

Title: Data processor
Inventor: YAMADA YASUTOKU
IPC: G11B20/10
Filed: 1994-02-18
Abstract: PURPOSE:To ensure the storage capacity of data to the full while the data is prevented from being overwritten in a storage means by a method wherein, when a control means receives a synchronous signal from input data, the storage means and a data processing means are then controlled on the basis of the synchronous detection signal at every counting operation of an input data amount to be stored. CONSTITUTION:When an input synchronous detection part 51 for a CD-ROM signal processing part 5 detects a synchronous pattern from input data D, it generates a synchronous detection signal so as to be input to a controller I/F 53. The synchronous detection signal is input also to an interpolation synchronous counter part 52, a synchronous detection signal is generated so as to be input to the I/F 53 whenever prescribed bytes are input. The I/F 53 calculates the logical OR of the two synchronous detection signals so as to be supplied to a controller 11. The controller 11 nullifies the synchronous pattern detected from the data D while the data D is being written into a RAM 6 for error correction, and only the signal by the counter part 52 is controlled so as to be effective.

Title: Generator with engine
Inventor: YANO HIDEO
IPC: H02P9/08
Filed: 1984-02-10
Abstract: PURPOSE:To preferably accelerate a generator in a low speed range by suppressing the output of the generator until the rotating speed of an engine becomes the prescribed value or higher. CONSTITUTION:When a switch 6 is closed, a field current is flowed to a field coil 1 through a transistor Q1. At this time, since a transistor Q5 is in OFF state, and the base current of the transistor Q1 is reduced by a resistor R8, the output voltage of the generator 1 is suppressed to a low value. When the rotating speed of the engine becomes the prescribed value, the transistor Q5 becomes ON, and a resistor R8 is shortcircuited. Accordingly, the output voltage of the generator 1 is controlled to a set value. Thus, the acceleration of the generator in a low speed range can be improved.

IPC: H04B7/185
Filed: 1981-02-17
Abstract: PURPOSE: To lower the cost of a receiver, by using a receiver that works on the clock of a low frequency when the transmitting data series is received.  
     CONSTITUTION: A PCM data series is supplied to error correcting encoders 49∼ 60, and the coding of error correction is carried out for each channel. For instance, a block code obtained by combining a BCH code and a parity code is used for an error correction code. The output data series of encoders 49∼60 are supplied to synchronism adding circuits 61∼72, and the block synchronous signals are added. In such way, the redundant bits for the error correction and for the synchronism are added to 1∼12 channels each and then supplied to a multiplexer 73 to receive the time-division multiplication. Accordingly an error correction is possible for the receiving data of a desired channel at the receiver side with a bit rate lower enough than the bit rate of the transmission mode.
