IPC: B60L5/24
Filed: 1993-02-16
Abstract: PURPOSE:To provide a current collector for railway in which a countermeasure is taken for lift as well as aerodynamic noise. CONSTITUTION:A shoe body 3 has cross-sectional area largest in the central part and decreasing gradually toward the right and left ends.

Title: Liquid ejection recording unit
Inventor: TERASAWA HIROHARU
IPC: B41J2/175
Filed: 1984-02-15
Abstract: PURPOSE:To arrange so that an impact force in a feeder tube caused by the sudden start and stop of carriage shift and bubbles may not reach a nozzle part by forming an air chamber containing a constant amount of air in the upper section of an ink tank for feeding ink to the nozzle. CONSTITUTION:The decrease in the ink amount caused by ink ejection from a nozzle part is replenished with an equivalent amount of ink fed into an air trap from an ink tank through a feeder tube 8, because an air chamber A inside the air trap is kept airtight by a valve 50. Even in case bubbles are mixed into a feed passage, these bubbles are caught by the air trap, so that the bubbles are not transported into the nozzle part. A change in the ink pressure caused by an inertia force of ink in the feed passage following the sudden start and stop of the shift of a liquid ejection recording unit, is reduced by the air chamber A in the air trap.

Title: Mold-registering mechanism of mold device
Inventor: HIRANO JUNJI
IPC: B29C33/30
Filed: 1990-02-06
Abstract: PURPOSE:To obtain the mold-registering mechanism which suppresses the effect of the displacement due to the thermal expansion of a mold by a method in which fitting holes are provided in the central position in the direction of the porting face of at least three side walls in the four side walls which constitute the outer wall-surface of a mold, and the standard pins which position the mold by fitting the pins into the fitting holes are provided on a holding frame. CONSTITUTION:A mold 14 is placed on a holding frame 10, and the mold is positioned on the holding frame as that the standard pins 16, 38, 39 of the holding frame are fitted into the fitting holes 60, 62, 64 of the mold. Since the fitting holes are provided in the central positions of at least three side walls in the four side walls of the mold, the central position of the mold is specified from the position of three fitting holes, and the mold is registered to the holding frame by using the central position of the mold as standard. Then the mold is heated at high temperature and the mold is thermally expanded in all directions, while the central position of the mold is assumed as standard. Lead frames 66, 68, 70, 72 are placed on prescribed positions of the mold and are sealed in the mold. Accordingly, the displacement due to the thermal expansion of the mold becomes the position-error relative to the lead frame. Consequently the position error relative to the lead frame may be suppressed to half or less. The property of the molded product with the lead frame which has high density is improved.

Title: Information storage medium
Inventor: YONEYAMA KOICHI
IPC: G11B23/00
Filed: 1989-02-06
Abstract: PURPOSE:To contrive to shorten the access time and to improve the reliability at the time of processing the data by forming a part to be engaged which is engaged to an engaging part of a slip preventive member formed on a medium supporting means side on the surface of a hub. CONSTITUTION:In a state that an information storage medium (disk) 1 is supported by a medium supporting means (turntable) 11, a part to be engaged 17 formed on the surface of a hub 6 of the disk 1 becomes a state engaged to an engaging part 16 of a slip preventive member 15 formed on the table 11 side. Therefore, even if large inertial force works by allowing this medium to rise at a high speed or allowing it to fall at a high speed, or rotating it at a high speed at the time of recording and reproducing the data, a slip between them is prevented. In such a way, shortening of an access time and an improvement of reliability at the time of processing the data can be contrived, and a high speed processing can be executed with high accuracy and stably.

Filed: 1983-02-23
Abstract: PURPOSE:To obtain precise takeout of predetermined number of articles by providing a click-equipped conveyor with a stopper, leaving a clearance that ermits only predetermined number of articles to go through. CONSTITUTION:The inclined bottom end of a tray 22 supported in a slant attitude is provided with an opening, through which a click 23 installed on a belt 24d can pass, and a stopper plate which prevents a book 5 from dropping off the tray 22. While the book 5 in the tray 22 is pulled up for takeout with the click 23 as the belt 24d rotates, the subsequent book that is pushed against the book 5 now being pulled up is also pulled up. On the other hand, by maintaining a clearance between the surface of the belt 24d and a guide plate 27 to the extent that only one of the book 5 can pass through, books other than the book 5, which are also pulled up but not desired to be taken out at that time, hit a stopper plate part 27a and are prevented from being pulled out of the tray. With this contrivance, only the required number of books can precisely be taken out.

Title: Secondary air-supplying device of engine with supercharger
Inventor: ODA HIROYUKI
IPC: F01N3/34

Abstract: PURPOSE: To supply a necessary and sufficient secondary air irrespective of a low load or high load of the engine by a method wherein there are provided a turbine upstream of the supercharger and the first, second air supply passages which communicate an exhaust passage and a suction passage at a downstream of a blower.  
     CONSTITUTION: Since an exhaust pressure is small and in addition, a pulsation of an exhaust gas is maintained entirely in the exhaust passage 2 at the upstream of the turbine 4 when the engine E is in the operation with a low-load, a check valve 8 is opened by a negative pressure of the exhaust gas pulsation to supply the air as the secondary air from the first secondary air supply passage 7 to the exhaust passage 2, and the secondary air supplied is consumbed for purifying the exhaust gas in an exhaust gas purifying device 6. As a result that the blower 5 is driven by a high power and the amount of the supercharged air is increased when the engine E is applied with the high load, the 2nd secondary air supply passage 10 in place of the 1st secondary air supply passage 7 permits a part of the supercharged air as the secondary air to be supplied to the exhaust passage 2.

Title: Semiconductor device and selection method of perfect semiconductor device
Inventor: IDE KAZUNORI
IPC: G01R31/28
Filed: 1995-01-25
Abstract: PURPOSE: To select quickly and easily whether a device is perfect, without exerting influence upon the yield of products. CONSTITUTION: A circuit part 3 for operation checking is formed in an I/O terminal part of an IC part 2 of a semiconductor device 1. A heat-sensitive resin layer 11 is formed on the upper layer of the circuit part 3, in which a transistor as a heating element is arranged in each of the I/O terminals of the IC part 2. When abnormality is present as the result of operation checking, an excessive collector current is applied to the transistor connected with the corresponding I/O terminal and heat is generated. Hence the corresponding region of the heat-sensitive resin layer 11 on the collector is discolored. The heat-sensitive resin layer 11 is sensitively discolored by comparatively small heating value, and the change appears on the surface of the semiconductor device 1. By visually recognizing the change, whether the device is perfect is selected.  Since the heat-sensitive resin layer 11 is used, the current applied to the transistor can be reduced, and its time also can be shortened.
