Inventor: FUJIWARA MUNEYOSHI
IPC: B23P21/00
Filed: 1993-01-12
Abstract: PURPOSE:To improve mounting efficiency of electronic components and mounting quality by measuring the warp amount of a circuit board with a displacement sensor. CONSTITUTION:When target marks at two points on a circuit board 17 are recognized with a camera head 20, the warp amount of the circuit board 17 is measured at a plurality of arbitrary points between the two points by using a displacement sensor 1. The end point of the period in which an XY table 18 can move is set to be a time point when a suction nozzle 13 descends as far as a position where the distance between the tip of the suction nozzle 13 and the upper surface of a circuit board 17 becomes equal to the sum of two times height of an electronic component of the maximum height dimension and the maximum warp amount of the circuit board 17. The beginning point of the period in which the XY table 18 can move is set to be a time point when the suction nozzle 13 ascends as far as the distance between the tip of the suction nozzle 13 and the upper surface of the circuit board 17 becomes equal to the sum of the height of the electronic component of the maximum height dimension and the maximum warp amount of the circuit board. Hence the moving period of the XY table can be set to be long.

Abstract: PURPOSE:To reduce a tape speed error by winding up a magnetic tape at a constant speed at the time of detecting a control signal, and when the signal is not detected, controlling the sum of pulse periods of two pulse generators to a fixed value to wind up the tape almost at a fixed speed. CONSTITUTION:Approximate tape speed information is obtained from a period sum calculating circuit 53. Thereby, a period sum subtracting circuit 7 outputs an error between the value of the circuit 53 and the value of a target period summing circuit 61 to a switching circuit 10. At the time of receiving the output of a pulse detecting circuit 8, the circuit 10 outputs the value of a period subtractor 93 to a motor driving circuit 4 when a control signal is detected, or outputs the value of a period sum subtractor 7 to the circuit 4 when no control signal is detected. The circuit 4 generates the torque of a motor 3 in accordance with the size of the input value and winds up the tape 1 around a reel 1a. Namely, when the control signal is detected, the period of the signal is controlled to the fixed value and the tape 1 is wound up at the fixed speed, and when no control signal is detected, the sum of pulse periods of the pulse generators 51, 52 is controlled to the fixed value and the tape 1 is wound up almost at the fixed speed.

Title: Picture transmission body
Inventor: IMOTO MASATAKA
IPC: G02B6/08
Filed: 1984-01-13
Abstract: PURPOSE:To obtain a picture transmission body characterized by a simple structure and easy manufacture by laminating many transparent sheets so that the direction of projected stripes of respective sheets coincide with each other and the interface of respetive sheets is allowed to contact with a layer having a refractive index smaller than that of the transparent sheet and forming an incident end and a projecting end. CONSTITUTION:Many projected stripes 2 extended in the longitudinal direction X are adjacently formed. One end of the picture transmission body is used as its incident end I and the other end is used as its projecting end O to transmit light. Namely, light L1 made incident from the incident end I is repeatedly reflected on the surface of the projected stripes 2, made to run like L2-L4 and projected from the projecting end O like L5. Since the interface of the projected stripes 2 is allowed to contact with a layer having a refractive index smaller than that of the projected stripes 2, almost all the light rays are transmitted as mentioned above while being fully reflected. Since the transparent sheet-like substances 1 on which many projected stripes 2 are formed are used, there is no dispersion, an image similar to the one obtained from a picture transmission body obtained by arraying optical fibers is obtained and the working property is high because of the lamination of the sheets.

Title: Liquid crystal element and its manufacture
Inventor: MIZUNO SUKENOBU
IPC: G02F1/1337
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To prevent a defective picture from being produced and deterioration of display quality. SOLUTION: When cooled, a liquid crystal 2 tends to shrink its volume so as to generate a gap part. In a liquid crystal panel P1, however, because a recessing part 4, in the state the liquid crystal 2 is not filled therein, is formed in a non-pixel region C, the gap part A1 is generated inside the non-pixel region C utilizing the recessing part 4 as a nucleus and is not generated in the pixel region D. Consequently, a defective picture caused by generation of a gap part in the pixel region D and deterioration of display quality accompanied therewith are prevented.

Title: Dynamic display circuit
Inventor: SHOJI MASAHIKO
IPC: G09G3/32
Filed: 1988-01-12
Abstract: PURPOSE:To reduce the excessive current flowing to a display element and switching noises by inserting an integration circuit which separates the driving signal and display signal of the display element from each other and makes the leading edge and trailing edge of a pulse current are dulled between the display element and an indirect display circuit. CONSTITUTION:Each of the display elements of a display section 10 is constituted as a display unit DU composed of an LED, indirect display circuit 62, and integration circuit 64. The indirect display circuit 62 receives the output of a buffer 54, namely, a display elements group selecting signal S1 and outputs of buffers 51-5m which are an intra-group display element selecting signal S2, and outputs a display signal S3 which is the AND of the above-mentioned signals and outputs and drives the display element LED. Upon receiving the display signal S3, the integration circuit 64 supplies a pulse current (i) whose leading edge and trailing edge are dulled to the display element LED. Therefore, the same brightness is obtained with the pulse current whose amplitude is narrower as compared with conventional pulse currents (approximately, the brightness is proportional to the integrated value of the electric current). As a result, no large-current pulse is made to flow to the display element LED and occurrence of noises caused by pulses is eliminated.

Title: Ghost eliminating device
Inventor: MORIMOTO YOUICHI
IPC: H04N5/21
Filed: 1982-01-14
Abstract: PURPOSE:To eliminate a ghost signal just after channel switching, by providing a memory for tap gain setting corresponding to each channel. CONSTITUTION:A ghost detection circuit 3 picks up a small section including the ghost of the front ridge of a vertical synchronizing signal from a subtractor 2 and converts the signal into a digital signal at each sampling point. An operation processing circuit 4 converts the said signal into data representing the amplitude and time location corresponding to each stage of a transversal filter 1 and conducts it to memories 6a-6n. In selecting the 1st channel, the data processed as mentioned above from a TV signal from the ghost detection circuit 3 and the circuit 4 is written in the memory 6a. The same processing is done for all the memories 6a-6n. The data of a selected memory at each channel switching is given to a tap gain switching circuit 5 via an OR gate 8 and the tap gain of each stage of the filter 1 almost at the same time of switching is set to an optimum value for the formation of the correction signal. Thus, the picture eliminating ghost is reproduced.
