IPC: F21V21/36
Filed: 1988-09-30
Abstract: PURPOSE:To decrease the space for installing a close contact spring using a simple construction and lessen the recess depth of a lighting fixture by fitting close contact spring between a bend and a socket mounting frame. CONSTITUTION:A close contact spring 18 is installed along a guide bolt 17 fitted between a bend 10a and a socket mounting frame 12. When an elevating/ sinking part 8 is to be sunk, it is once elevated in order to disengage a lock 9, and the spring 18 is compressed to allow a supporting frame 10 to rise to cause unlocking, and then a driver device is operated reversely to sink the elevating/sinking part 8, which sinks also the illumination light part such a lamp 14. When the lamp is elevated, the illumination light part comes in contact with the ceiling in the max. elevated position to cause stop of the elevating motion, and a further lift of the part 8 compresses the close contact spring 18 to cause elevation of the part 8, and at the same time, the resilience of this spring 18 presses the illumination light part to the ceiling surface to attain close contact. At the same time, the part 8 is detained with the lock 9 to be locked. This eliminates a special space for installation and lessen the recess depth of the lighting fixture.

Abstract: PURPOSE:To accurately detect the end point of a PCM section by comparing the count value of a control means with the final value of a PCM signal and then using the output as a reference timing when a block address is judged to be an error. CONSTITUTION:A clock is reproduced according to the output signal of a reproduction amplifier in a data strobe 108 and at the same time a data 0/1 is output to a protection circuit 109 via a demodulation circuit 118 as a determined signal in synchronization with the block. The circuit 109 detects a synchronizing signal by a synchronizing signal detection circuit 113 according to the output signal of the strobe 108, checks continuity at an address continuity check circuit 114, and then performs error detection at an error detection circuit 115. Then, a judgment circuit 116 determines an error according to the information from the circuits 114 and 115. When it is determined that an error occurred, the value of a block address is ignored and is counted up and the count value is compared with the final value of the address of the PCM signal, thus accurately detecting the end point of the PCM section with the result as the reference timing for recording and reproducing the area.

Title: Method and apparatus for forming spring and product thereof
Inventor: MAAKU EI KENPU
IPC: B21C51/00
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To uniformalize the dimensions of a spring and other parameters. SOLUTION: The spring 30 is formed by feeding out a wire 16 from an outlet 18 which a quill 14 fixed and by abutting the wire 16 on the wind-working surface 24 of a wind-working tool 20 to bend the wire 16. When the spring 30 is formed, the position of the wire 16 is detected by the probe 33 of a LVDT32, and a signal indicating its position is outputted by the LVDT32. According to this signal, the position of the wind-working surface 24 is controlled by the wind-working tool 20. After finishing the forming of one spring, the position of the wind-working surface 24 is detected by a laser beam machine 66. When a next spring is formed, by adjusting the wind-working surface 24 to the position, the spring is formed. Therefore, in one spring, the parameter of the spring can be uniformly maintained over all the winding parts.  Also, in plural springs, parameters can be uniformly maintained over all the springs.
