Abstract: PURPOSE:To miniaturize the whole of a driving arrangement for motor cars and improve the pinion accuracy of the shaft of its motor, by spline-joining one end part of a pinion to the output shaft of the motor, and concurrently, by bolt-fixing the pinion on the output shaft with a predetermined bolt via a through hole bored in the center axis part of the pinion. CONSTITUTION:A pinion 11 is spline-joined-in its one end part to an output shaft 1A of a driving motor 1, and a blind hole 1a is bored in the central part of the end part of the output shaft 1A along its axial line, and further, from the opening part side thereof, a spigot part 1b and a screw hole part 1c are formed in succession. Also, on the outer periphery of the output shaft 1A, an axial spline 1s is formed, and in the center axis part of the pinion 11, a through hole for spigot-joining it to the output shaft 1A is bored, and then, by a pinion bolt 15, the pinion 11 is bolt-fixed on the output shaft 1A of the driving motor 1 while it is spigot-joined to the output shaft 1A. As a result, the output shaft IA of the driving motor 1 and the center axis of the pinion 11 are so set as to coincide with each other, and both can be one with each other firmly, and thereby, the pinion accuracy of the shaft of the motor 1 can be improved without the deterioration of the miniaturization of the whole of a driving arrangement for motor cars.

Title: Pressure control valve
Inventor: NAKASHIMA TAKEO
IPC: F16K17/10
Filed: 1980-06-24
Abstract: PURPOSE: To lessen override of pressure by providing a ring-shaped groove composed of two or more inclined surfaces behind the seat face of the main valve of pressure control valve.  
     CONSTITUTION: When high-pressure fluid flows in the direction shown by the arrow A, a negative pressure, whose absolute value becomes larger with approach to the seat face 2 and becomes about 0 around the minor diameter part D 1 , is applied to the inclined surface B of main valve 10. To an inclined surface 14 is applied such a positive pressure from minor diameter part D 1  as growing with going further from the seat face 2. These negative and positive pressure are oriented normally to the inclined surfaces 13, 14 and the components thereof act in the direction against the flow force F. That is, the force F 1  acting against the flow force F is the sum of the component F 13  of the neg. pressure applied to inclined surface and the component F 14  of the pos. pressure applied to inclined surface 14. Thus, the flow force F can be canceled perfectly by selecting the angles α, β properly.

Abstract: PURPOSE: To eliminate the necessity of a pickling apparatus, a liquid honing apparatus, etc., in a cold tandem rolling pass for a hot rolled strip whose surface condition is comparatively unimportant, by installing a differential roll speed rolling mill in front of the cold tandem mill.  
     CONSTITUTION: A hot rolled strip 1 is fed to a cold tandem mill 2. A scale layer is sticking to this strip 1 as a result of the hot rolling pass; a differential roll speed rolling mill, provided with work rolls 4, 5 rotated at different circumferential speeds, is installed in front of the cold tandem mill 2 for previously removing the scale layer. In this differential roll speed rolling mill, its draft percentage is set at as high as 5W 30%, and the circumferential speed V 0  the lower work roll 5 is made faster than V 1  of the upper work roll 4; hereby, cracks are generated in the scale layer, whose greater part is then rubbed to fall off. This preliminary rolling pass according to the said conditions enables the reduction of the overall draft percentage of the cold tandem mill.

Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To improve the action precision of a registration roller by correcting the timing of clutch engagement in consideration of the clutch engagement period by a clutch engagement period measuring means. SOLUTION: A clutch is turned on when a measuring sensor 303 is shielded by a shielding plate 302, a timer counter is started when the clutch is turned on, the timer is stopped when the measuring sensor 303 detects light, and the clutch is turned off. The clutch engagement period Tc is calculated from the value of the timer counter based on the rotating speed of a registration roller 301 and the size of the shielding plate 302. The drive timing T of the registration roller in reference to the vertical synchronization signal is determined based on the distances from the registration roller 301 to a photosensitive drum and the nip section of a transfer roller and the distances from the radiation position of a light beam on the photosensitive drum to the photosensitive drum and the nip section of the transfer roller.  When T>=Tc, the registration clutch is turned on at the timing of T-Tc from the vertical synchronization signal.

Abstract: PROBLEM TO BE SOLVED: To effectively process invalidation information which is needed for prevention against abuse of a card by generating two kinds of invalidation information divisionally and transmitting the information from a card information control station to a card use station through a central information processing station. SOLUTION: The control station 2 generates the invalidation information in unique format. At this time, the invalidation is generated as one of two kind of regular invalidation information and emergency invalidation information. Here, regular invalidation is generated periodically every month for the reason of cancellation, the loss of the card, etc., and emergency invalidation is generated in case of the loss, steal, etc., of the card. Either of them is stored in an invalidation information file after being generated, and transmitted to the central information processing station 4 through a communication network 5. The processing station 4 receives the invalidation information from the control station 2, updates an invalidation file, and sends the invalidation information to respective use stations 3 through the communication network 5.  Each use station 3 receives the invalidation information sent from the process station 4 and delivers it to respective stores.
