Abstract: PURPOSE:To improve the reliability of contact by pressing a flexible sheet which hermetically closes the top of a pair of contacts formed on a printed wiring board with an insulating spacer by means of a bowl-shaped elastic body having pressing projections. CONSTITUTION:The bowl-shaped elastic body 6 formed internally with a pair of the pressing projections 6a, 6b which vary in height is depressed by the operation of a key 2.

Title: Method for changing ingot width
Inventor: TENMA MASAMI
IPC: B22D11/16
Filed: 1985-05-21
Abstract: PURPOSE:To make possible the change of a billet width in the shortest time by determining the speed up rate of the horizontal moving speed on the short sides of a casting mold and the angular speed of a swiveling device by a prescribed method and maintaining constant these speeds during the former and latter periods of the movement of the short sides thereby changing the width. CONSTITUTION:The speed up rate alphas of the horizontal moving speed of the short sides is preliminarily determined with the permissible deformation resistance of a shell as a parameter in the stage of changing the width of the steel ingot by a short side driving device. The angular speed omega of the short side swiveling device is determined by the equation omega=alphas/Uc (where Uc: casting speed). The horizontal moving speed Vh is increased or decreased at the specified speed up rate alphas and the angular speed omega is maintained constant, then the width is reduced (a) or expanded (b) to the desired size in the former tilting period and latter tilting period of the short sides in the stage of changing the billet width. The change of the ingot width in the shortest time during continuous casting is thus made possible.

Abstract: PURPOSE:To improve the energy availability of a fuel cell by using an inert gas as a substitution gas at the starting or stopping time of power generation by separating and forming from the gas or air of a reformed burner by using dump power which a fuel cell generates even at the time of a light load. CONSTITUTION:The output current control portion 6 of a fuel cell 1 outputs a signal 6 to command a start of the driving motor 14M of a compressor 14 to an auxiliary power source 8 when the total of a load current IL and an auxiliary current Is drops to a prescribed level or less, and concurrently controls the fuel cell 1 and a fuel reformer 2 so that the driving current Ib of the motor 14M is additionally supplied. For this, inert gas for substitution is produced by making use of dump power at the time of a light load. A required quantity of CO2 enriched gas 11B is stored all times in a tank 15 to create a waiting state of gas substitution. It is thereby possible to use inert gas as substitution gas at the time of start or stop of power generation and improve the energy availability of a fuel cell.

Abstract: PURPOSE:To enable the stabilization of pulling-out of a ribbon, by forming an irregularity for detent on the central core of a feeder spool, and by providing a detent spring which presses the irregularity with one end and the outer peripheral surface of the feeder spool with the other. CONSTITUTION:An arm 17a of a detent spring 17 engages with a knurling irregularity 14a of the central core 14 of a feeder spool 16, giving a back tension to a ribbon.

Filed: 1988-05-02
Abstract: PURPOSE:To effectively remove the bad influence of a high luminance subject by controlling the use of a high luminance component for focusing detection according to an filter means to be selected according to the degree of focusing. CONSTITUTION:In the case where the output of the BPFs 28, 30 of a low and intermediate band or a high band is selected, high luminance is removed by impressing the detected output of a high luminance detection circuit 24 to an AND circuit 38. On the other hand, in the case where the output of the BPF 26 of an extra-high band for focusing decision is selected, a signal line between the high luminance detection circuit 24 and the AND circuit 38 is cut off. Thus, by making the output of the high luminance detection circuit 24 effective for the BPFs 28, 30 of the low and intermediate band or the high band, and ineffective for the BPF 26 of the extra-high band as linking with the selection of a switch 32, the high luminance subject harmful in a picture at the time of a heavy blur can be removed, and besides, the high luminance subject effective for the focusing decision or contained in an extra-high band component can be remained as it is.

Abstract: PURPOSE:To lessen not only the lowering of saturation magnetization and to improve magnetic coersive force but also to improve the filling density when magnetic powder is formed into a bonded magnet, and also to lessen the quantity of gas generating at the time of jet pulverization by a method wherein, after magnet material of rare earthiron based nitride has been pulverized by a jet pulverizer, the pulverized powder is finely powdered. CONSTITUTION:Magnetic material is pulverized into a suitable particle size by a jet pulverizer in which raw material particles, accelerated by the pressure fluid of the inert gas such as air, nitrogen, helium, argon and the like, desirably mixed gas of nitrogen and air, are pulverized by the collision between raw particles or by the collision against the wall of the pulverizer, and the subsequent pulverizing operation is conducted by a wet pulverizer. At this time, the range of particle size of a jet pulverizer is average particle diameter of 2.5 to 20mum, desirably 2.5 to 10mum. Subsequently, the above-mentioned material is finely pulverized to the average particle diameter of 1 to 3mum using a wet pulverizer. As a result, the lowering of saturation magnetization is small when compared with the fine powder manufactured by the pulverizing method heretofore in use, and coersive force can be improved.
