Title: Upper trough of electromagnetic trough
Inventor: HOSHIKA HARUO
IPC: H02K44/06
Filed: 1987-02-25
Abstract: PURPOSE:To eliminate a distortion by induction heating of an apparatus and lengthen its life by forming both side walls and a bottom wall into an integral body by means of a castable refractory material and by providing connecting plates maintaining and reinforcing the bottom at spaces each by an even number of times as long as the pole pitch of an inductor and at a right angle to the lengthwise direction of a melt passage. CONSTITUTION:A melt passage 1 is formed into an integral body by means of a castable refractory material and its both sides are maintained by both side plates 2a, 2b of SS material. An upper trough is fitted at both ends with connecting flanges 5a, 5b for every given length. A non-magnetic connecting plate 3 is reinforced by connection of the lower edges of both side plates 2a, 2b by means of a plurality of narrow non-magnetic connecting plates 3 at right angles to the lengthwise direction of the melt passage 1. A space between said non-magnetic connecting plates 3 is an even number of times as long as the pole pitch of an inductor. Therefore, shifting magnetic fluxes passing through the non-magnetic connecting plates 3 offset each other apparently to enable elimination of a distortion by induction heating. Also, the melt passage 1 has a long life, because it is formed into an integral body and has no joint surface to generate no difference in melt.

Title: Bicmos gate circuit
Inventor: KUROSAWA SUSUMU
IPC: H03K17/567
Filed: 1990-02-20
Abstract: PURPOSE:To prevent the operating speed from being rapidly deteriorated even when a power supply voltage is decreased by connecting the drain electrode of a MOSFET to the base electrode of a bipolar transistor(TR) so as to apply a large voltage between the gate and the source of the MOSFET at all times. CONSTITUTION:When an NPN bipolar transistor(TR) Q1 is turned on and a load is charged at high speed, at least one of N-channel MOSFETs N1, N2 is turned off and the base-emitter of an NPN bipolar TR Q2 is biased reversely, then no effect is given onto the operating state of the Tr Q1. Moreover, when the TR Q2 is turned on and the load is discharged at high speed, both P-channel MOSFETs P1, P2 are turned off and the base-emitter of the TR Q1 is biased reversely, then no effect is given onto the operating state of the Tr Q2. Thus, even when the power supply voltage is decreased, the operating speed is not remarkably deteriorated.

Title: Engine driven-type compressor
Inventor: FUKUHARA YOSHIFUMI
IPC: F04B49/02
Filed: 1980-03-29
Abstract: PURPOSE: To reduce operating time required for engine starting by making it possible to restart immediately even a compressor equipped with a large air tank.  
     CONSTITUTION: A pressure required for opening a pressure regulator valve 50 is set to the same pressure for a pressure control valve 14 or less, and the valve closing pressure is set to the pressure higher than that of the pressure regulator valve 14. Therefore, if the pressure is lowered due to the consumption of the compressed fluid inside a large air tank, the pressure regulator valve 50 is closed sooner and forces nonload operation of a fuel supply system 43 to be restarted in an early stage through an operating system 35. When the pressure inside the air tank 8 is lowered, the pressure regulator valve 14 is closed. When a manual valve opening system 24 is operated in this case, the compressed fluid is fed into an unloader system 9 through a branch pipe 51 and the compressor 1 is placed into nonload operating condition. When a regulator handle 44 is then shifted from the stop position to the start position, the engine can run immediately. Since a quick restarting operation can be offered, the operating time required for starting the engine can be reduced.

Title: Evaluating method for helical scan reconstituted image
Inventor: HATANO KENJI
IPC: A61B6/03
Filed: 1994-03-11
Abstract: PURPOSE:To evaluate a reconstituted image with the method for evaluating a diagnostic part, the size of a diseased part and the condition of an arch-fact corresponding to moving speed and the reconstituted image under displaying while displaying the table moving speed. CONSTITUTION:The reconstituted CT image at an arbitrary slice position provided from the measurement of helical scan is displayed on the center of figure. Photographic conditions and image conditions are displayed on the left side of figure. On such a display picture, the 'table moving speed' is displayed. The table moving speed is table moving speed in helical scan at the time of providing the CT image. While displaying this picture, the size of the diseased part in the CT image or whether any arch-fact is caused or not is evaluated in the relation with the table moving speed. This evaluation causes the same effect as the increase of slice thickness caused by continuously moving a table during scan in the case of helical scan and the level of that effect depends on the table moving speed.
