Title: Defect detecting method for printed wiring
Inventor: NISHIKAWA YUKIO
IPC: G01B21/30
Filed: 1980-12-03
Abstract: PURPOSE:To detect a defect quickly and exactly, by making a vertical part of an electric conductor pattern meet at right angles with a scanning line, so that a picture output signal of the relevant part can be made equal to width of the electric conductor pattern. CONSTITUTION:When positions of a leading edge and a trailing edge of an electric conductor pattern 3 in case when the left end being a scanning start point of a printed circuit board 1 has been made a reference are denoted as A and B, B is constant and A is varied monotonously in the section to scanning lines 4-1-4-n being a shifting part to an oblique line from a vertical line, and in the section to scanning lines 4'-1-4'-n being a shifting part to the vertical line from the oblique line. In a 45 deg. refracted part of the electric conductor pattern 3, its width variation is continued for some period, therefore, it can be discriminated from hair or a flaw, also can be discriminated from a swing since its motion is different. Therefore, a picture output signal of the electric conductor pattern 3 is processed by dividing it into a straight line part and an oblique line part, and a defect is decided with high accuracy by use of a width set value.

Title: Forming method of moving block for rolling guiding device
Inventor: TERAMACHI HIROSHI
IPC: F16C29/06
Filed: 1995-06-14
Abstract: PURPOSE: To provide a forming method in which two pair of left and right ball rolling grooves of a moving block are fitted into supporting projected parts of a circular arc cross sectional metal mold having approximately the same radius of curvature as that of a ball so that they are integrally formed and a position of a resin part formed to the moving block can be assuredly set. CONSTITUTION: Two pair of left and right ball rolling grooves 7, 8; 7, 8 of a moving block 4 are fitted into supporting projected parts 14b of a circular arc cross sectional metal mold 14 having approximately the same radius of curvature as that of a ball so that the moving block 4 is assuredly supported by four points in such a way that the two pair of left and right supporting projected parts 14b are put among the upper, lower, left and right parts thereof.

Patent JP-S5694838-A (JP)
Title: Driving circuit
Inventor: KOIKE HIDEJI
IPC: H03K19/094
Filed: 1979-12-27
Abstract: PURPOSE: To increase sufficiently the gate bias of a driving transistor, by securing a serial connection between the two units of the capacitor for boostrap and then charging independently these capacitors up to the power supply voltage.  
     CONSTITUTION: When the potential of the input terminal P becomes a low level, the MOS transistors 11, 12 and 15 are turned off. Thus the current flows to the load 20 via the transistor 16 plus capacitors 18 and 19. The final interterminal voltage V 1  of the capacitor 18 turns to VDD-VT, and the transistor 14 conducts in the course of the change from V 1  to VDD-VT. Thus the capacitor 19 is charged. As a result,  the final interterminal voltage V 2  of the capacitor 19 turns to VDD-VT. The gate- source voltage of the driving transistor 17 increases in the rising process of V 1  and  V 2 . Thus the final potential of the output terminal Q becomes VDD. Accordingly, the gate potential of the transistor 17 is increased finally up to V 1 +V 2 +VDD=3VDD- 2VT.

Title: Automatic closing instrument
Inventor: RAINAA SHIYUTORANGUFUERUTO
IPC: F16K21/12
Filed: 1984-08-20
Abstract: A self closing valve has a housing with a water inlet and outlet and with a valve piston positioned inside it in such a way that the end of the piston facing away from the valve seat demarcates a discharge chamber in conjunction with the inlet and outlet through flowthrough passages that are activated in opposite directions by supplementary-valve controls in such a way that the duration of operation is determined by a decelerated opening stroke of the valve piston and closure is activated by a rapid closing stroke of the valve piston. The initiating position of the supplementary-valve controls that is provided during the opening activation of the valve piston is designed to maintain itself hydraulically as the result of a pressure difference generated at a choking device as the result of the flow through the valve and discontinuing the automatic maintenance shifts the supplementary-valve controls. Any leakage flows that may occur at the self-maintaining members are diverted to the outlet, without being choked off, through the supplementary valve that is opened by means of the initiating position of the supplementary-valve controls and the supplementary valve closes once self-maintenance and the shift in the supplementary-valve controls that is provided thereby have been discontinued, eliminating any potential bypass flow parallel to the flow through the choking device on the part of the flow through the valve.

Title: Uninterruptible changeover system
Inventor: TATSUNO HIDEO
IPC: G06F3/00
Filed: 1991-06-17
Abstract: PURPOSE:To prevent a phase jump from almost being taken place in a real cell stream of a path and a channel by implementing delay control of an information string in service at and after changeover of a transmission line in the unit of a cell length for a prescribed long period. CONSTITUTION:A parallel transmission circuit 15 of a transmission line changeover means of a sender side equipment 13 sends a same information string as an information string of an active transmission line 11 to a standby transmission line 12. Thus, a transmission line changeover means of a receiver side equipment 14 uses delay insert/ removal circuits 17, 18 to insert/removal of a delay in the unit of cell length for a prescribed period with respect to each information string from the active transmission line 11 and the standby transmission line 12 respectively. Then a control circuit 20 makes a delay set to one delay insert/removal circuit coincident with a delay of an information string controlled and outputted in the unit of cell length for a prescribed period with respect to the active circuit 17 and the standby circuit 18. When the active and standby delay quantities are coincident, a changeover circuit 19 selects an output of the standby circuit 18 from an output of the circuit 17. As a result, a phase jump of a real cell stream in the time division multiplex digital transmission is minimized to the utmost.
