Title: Method for reproducing neck of cathode-ray tube
Inventor: MATSUMOTO MASAO
IPC: H01J9/26
Filed: 1985-04-09
Abstract: PURPOSE:To increase the accuracy for reproducing the neck of a cathode-ray tube and automate the reproduction by locating the reference axis connnecting the centers of a first and a second restricting part on the vertical line and locating the center of a third restricting part on an extension of the reference axis. CONSTITUTION:A body 1 prepared by cutting off a neck from a cathode-ray tube is placed perpendicularly to a first and a second restricting part 23 and 24. At this point, the first part 23 restricts the position of the maximum true- circular section of the funnel cone which is used as the first reference and the second part 24 restricts the position of the given section 21a of a residual neck 2 which is used as the second reference. As the result, the central axis of the body 1 which connects the center of the cone of a funnel 5 and the center of the residual neck 21 automatically coincides with the reference axis (X-Y). In addition, a third restricting part 37 is used to position the central axis of a production neck tube 2 on the reference axis (X-Y). Since the body 1 and the reproduction neck tube 2 are fused after their central axes coincide with each other, it is possible to reproduce the neck of a cathode-ray tube with high accuracy.

Title: Control device for internal combustion engine
Inventor: KOMURASAKI SATORU
IPC: F02N11/08
Filed: 1986-04-01
Abstract: PURPOSE:To prevent undue power consumption, by determining whether or not a control device for an engine can normally operate from a power voltage in the control device, and making the operation of a starter invalid when the power voltage is in such a condition where a normal control operation of the control device cannot be provided. CONSTITUTION:The operational condition of a control device 5 is determined by a voltage signal 14, and the start of an engine is detected by a voltage signal 15. When it is detected that a power voltage of a microcomputer incorporated in the control device 5 is in such a condition where the control device 5 cannot normally operate at the starting of the engine, a low-voltage detector 13 is operated. As a result, a coil 12a in a magnet SW 12 is excited to open a contact 12b and thereby open a circuit of a coil 11a in a magnet SW 11. As a result, even when a key SW 2 is in the position of a fixed terminal C at the starting of the engine, a contact of the magnet SW 11 is not closed, and therefore no power is supplied to a starter 3 to inhibit the operation of the starter 3.

Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a push button structure of a gas meter which makes constant a force acting on a switching element without being influenced by a press force by an operator. SOLUTION: Each engagement element 61 of an engaging member 39 is inserted to an insertion hole 78 formed in a gas meter housing 27, thereby being engaged with an inner face 79 of the housing 27 and prevented from slipping off. A middle part of a pressing member 40 between end parts in a direction of an axis is coaxially inserted to an axial part 42 of a cover body 38 in a state while a press part is urged by a spring 41 to the downstream side in a press direction A1 more than the cover body 38, so that the pressing member 40 is held movably in the axial direction of the cover body 38. When the cover body 38 is pressed in the press direction A1, the press force is transmitted via the spring 41 and pressing member 40 to a switching element SW. A force acting on the switching element SW is thus made constant without being influenced by the press force by an operator.

Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a rotary compressor to feed given lubricating oil during operation, reduce an amount of lubricating oil flowing out of a suction pipe during a stoppage, and prevent the occurrence of a trouble due to oil compression during starting. SOLUTION: A crank shaft 4 is stopped by a press mechanism in a position wherein a feed oil passage 10 on the shaft side and the communication groove 15 of a bearing 6 are positioned facing each other during de-energization of an electrically-operated element. This constitution forms a communication passage 16 to interconnect the inner peripheral part of a rolling piston 7 and a gas refrigerant space in a closed container 1. During a stop, a gas refrigerant in the closed container 1 flows in the lower pressure side of a cylinder 5 through the side of the rolling piston 7. The low pressure side in the cylinder 5 is balanced with a pressure in the closed container 1 and inflow of lubrication oil 8 to the outside of a rotary compressor is prevented from occurring.  This constitution sucks the lubrication oil 8, flowing out to the outside of the rotary compressor, during starting, and prevents the occurrence of a trouble, such as the occurrence of oil compression causing seizure of the crank shaft 4.
