Title: Discharge gas cooling device for compressor
Inventor: ISHIYAMA TERUKAZU
IPC: F02C7/141
Filed: 1985-04-12
Abstract: PURPOSE:To enhance cooling capability by starting simultaneously both coolers at the starting time of a compressor in a cooling apparatus comprised of a main cooler and auxiliary coolers and stopping the auxiliary cooler when the outlet temperature of the cooling apparatus becomes more than a prescribed value. CONSTITUTION:When a gas turbine 1 is started and a seizing signal S is output to a compressor 2, the same signal S is supplied to the automatic start side terminal 4c of a main cooler 4 and to the automatic start side terminal 5c of an auxiliary cooler 5 via OR circuit OR1, and both the coolers 4 and 5 are simultaneously started. Thus, the cooling apparatus 3 is precooled. And when the discharge gas temperature from the compressor rises and the output of a temperature detector 7 becomes more than a prescribed value, '0' signal is output from the LOW contact of a monitor switch 9. This output is input in a holding circuit 11 via an inverter N3 and an ON-delay timer DI30, and after a lapse of 30sec the auxiliary cooler 5 is to be stopped.

Title: Alignment method for proximity aligner
Inventor: OTA TOSHIYA
IPC: G03B27/32
Filed: 1994-03-23
Abstract: PURPOSE:To realize highly accurate alignment between a mask and a photosensitive substrate while setting a large interval between them by determining the relative positions first and second alignment marks with respect to a luminous flux individually. CONSTITUTION:An automatic halving 25 is rotated to scan the vicinity of an alignment mark 27 on a mask 4 by means of a long beam. When the laser light LA2 aligns with the alignment mark 27, a detector 30 detects a diffracted light having highest intensity and the relative position between the laser light LA2 and the mask 4 is determined. A beam length switching shutter 26 is then shifted to form a short beam which is projected onto the vicinity of an alignment mark 28 on a photosensitive substrate 6 thus aligning the laser light LA2 with the alignment mark 28. When the relative position of the alignment marks 27, 28 is determined sequentially with respect to the laser light LA2, the mask 4 is aligned accurately with the photosensitive substrate 6 through the laser light LA2.

Title: Torque control type pulse tool
Inventor: ISHINO YASUSHIRO
IPC: B25B21/02
Filed: 1995-04-04
Abstract: PURPOSE: To easily make zero point reset at the certain time when any load is not generated by providing a means for allowing a torque sensor to perform zero point resetting in a fixed time until a first pulsating torque is generated after a switch is operated to start a rotational drive source. CONSTITUTION: When an on-off switch 34 is turned on, a torque sensor 21 regards this switching as a trigger signal to be reset at zero point in a specified time. That is, in a specified time (short time) when a first pulsating torque is not generated immediately after the on-off switch 34 is turned on, an electric motor 15 and a pulse force generating device 16 are in a pulse rise state to be in a state in which any substantial load is not applied. Then, a CPU 50 resets a compensating circuit 49 at zero point during this interval of time so that the output of the compensating circuit 49 becomes torque-zero. Thus, torque can be measured accurately.

Title: Fuel injection device for internal combustion engine
Inventor: YAMAMOTO TADAHIRO
IPC: F02D41/34
Filed: 1980-06-10
Abstract: PURPOSE: To enable fuel to be supplied stably to each cylinder by injecting fuel at every specific crank angle and setting injection start period within the range of a specific angle prior to the upper dead point of each cylinder.  
     CONSTITUTION: A control circuit sets injection start period in the range of 20W 120° prior to the upper dead point of each cylinder of an engine on the basis of reference position signal at every 180° from a crank angle sensor to permit 4 times of injection for 2 rotations of a crankshaft. Then, in injection timing represented by arrow an intake valve of cylinder #2 has been closed with reference to the upper dead point of cylinder #3, and it is found that cylinder #1 is in the middle of open valve period whereas the valve of cylinder #3 is not yet opened. Thus, almost all of injected fuel can be supplied to the cylinder #1 carrying out strong intake action by setting injection start period in the range of 20W120° prior to the upper dead point of the cylinder #3.

CONSTITUTION:Cracking is performed by using release paper 7' with perforations, the release paper 7' and an intermediate liner 6 are positioned on the upper surface of an expanding device body 1 as they are left as they are not peeled, and a cover 2 is closed. When a moving member 1a is shifted in the upper direction and a wafer section is lifted upward from the lower section of a tape 5, each chip in the wafer 4 is separated mutually along scribing lines 4a, the release paper 7' is cut along a perforation 7a, and the release paper 7' is peeled automatically from the tape 5 without peeling by a hand. Since the tape 5 is extended at that time, the sock liner 6 is also peeled together with the release paper 7', and the release paper in the external section of the perforation 7a is left as it is. Accordingly, the generation of the breakings and cracks of the chips can be prevented.

Title: Combustion device
Inventor: ITO MASARU
IPC: F23N1/00
Filed: 1986-04-04
Abstract: PURPOSE:To facilitates ignition, by providing an oil amount regulating device which increase the pass area of a feed oil line, running from a constant oil level device to which a fan delivery pressure is guided, during ignition. CONSTITUTION:A fan 24 feeds combustion air to an evaporating cylinder 17, and fan delivery pressure is guided to a constant oil level device 29 through a connecting pipe 26. Pressurized fuel is fed to the evaporating cylinder 17 through a feed oil pipe 33 and a fuel nozzle 27 for evaporation. The evaporated fuel is mixed with combustion air and is injected through a flow uniformizing cylinder 20, and low NOx combustion by total primary combustion is performed on the surface of a wire net cylinder 21. However, since an electromagnetic valve 34 is opened during ignition, the fuel pass area of a feed oil line, to which that of a bypass pipe 35 is added, is increased. Thus, the excess air factor of air-fuel premixture injected through the flow uniformizing cylinder 20 is increased over that during constant combustion, and ignition can be facilitated.

Filed: 1988-03-31
Abstract: PURPOSE:To improve efficiency for using the title system by providing no transmission system exclusively used for an interrupting voice and executing an exchange operation by connecting terminals for the number of housed lines with an exchange. CONSTITUTION:At the side of an exchange 19, when a special number dial or a function key for an interruption is operated, the data transmission between a telephone set main body 1 as a call receiving side and either a telephone set or a data terminal as the other party for the communication is temporarily stopped, a voice from a telephone terminal to request the interruption is transmitted to an interruption destination telephone terminal on a data channel, and at the interruption destination telephone terminal, when an interruption request is received, the request is sounded with the voice using the data channel. Consequently, it is unnecessary to specially provide a line for an interruption call, and for the exchange 19, the terminals for the number of the housed lines can be connected. Thus, the efficiency of the system can be improved.
