Abstract: PURPOSE:To prevent the breakdown of elements by detecting an increasing proportion of the current caused by short circuited faults of one or more transistors among a plurality of power MOSFETs, generating a fault signal and simultaneously stopping a gate driving. CONSTITUTION:A fault detection device is constituted of power MOSFETs 1a-1n a plurality of which are connected in parallel for constituting an inverter device of a laser oscillator, a gate amplifier 2 to drive it, stabilized power supply the stabilized power current, a DC rectifier 4, a differential amplifier 5, a setting 6 to set a threshold value at the time of faults of said FETs 1a-1n, a comparator 7 and a controlling device 8 to output an operation stopping signal F. Accordingly, even if any one of FETs 1a-1n has a short circuited fault, the power current to be supplied to the gate amplifier 2 from the stabilized power supply 3 increases, and the fault signal is transmitted to the controlling device 8 in case of being in excess of said threshold value. As the result, a gate driving is stopped.

Title: Pulse laser oscillator
Inventor: SATO TAKESHI
IPC: H01S3/23
Filed: 1988-11-10
Abstract: PURPOSE:To obtain a laser waveform where injection lock is applied to by changing the resonator length of a slave oscillator by changing voltage applied to a piezo element. CONSTITUTION:When a reset current 14 becomes small, the starting of laser of a slave oscillator 2 becomes faster. Also, since when the number of repetitions of pulse oscillator becomes large, power supply voltage of the slave oscillator 2 is reduced so that the starting time of laser light is delayed. These conditions are calculated by a computer 12 and is compared with the startup time when injection lock is applied to. Then, being based on this comparison result, the resonator length of the slave oscillator 2 is changed to allow application voltage of a piezo element 17 to be increased or fixed. Thus, a waveform where injec tion lock is applied to can be obtained.

Title: High-speed growth method for water-soluble crystal
Inventor: NAKATSUKA MASAHIRO
IPC: C30B7/00
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a high-speed growth method for a water-soluble crystal capable of greatly increasing a crystal growth speed as compared with the crystal growth speed of the conventional water-soluble crystal precipitation method. SOLUTION: A growth soln. of a high saturation state of a supersaturation degree of 10 to 200% is formed by impressing heat energy and acoustic energy on an aq. soln. of a crystalline material, then cooling the soln. A seed crystal is inserted into the growth soln. and the crystal is grown while soln. flow is formed near its crystal growth surface. The heat energy and acoustic energy are impressed on the soln. in the stage before the soln. is supercooled to the supersaturation state, by which the generation of clusters in the soln. is suppressed and the formation of general crystals is suppressed. The crystal material molecules in the growth soln. of the high supersaturation are thus deposited only on the crystal growth surface.

Filed: 1993-11-12
Abstract: PURPOSE:To remarkably shorten time to be consumed for the printing processing of a host computer connected to a network by successively storing printing data sent from a master device in a secondary storage device as a file and printing out the stored data in parallel in the received order. CONSTITUTION:At the time of receiving printing data from one of plural host computers through a host interface 211, the data are written in a secondary storage device 213 as a file and its file name is written in a printing order list file previously prepared in the device 213. Printing processing is executed in the file order written in the list file. At the time of receiving printing data from another host computer during the period of printing processing, a CPU 212 is interrupted and a file is prepared by the interrupting processing. Thereby the receiving processing of the printing data can be quickly executed, so that waiting time at the time of instructing printing from another host computer can remarkably be shortened.

Title: Capacity control device for variable capacity compressor
Inventor: HIROTA HISATOSHI
IPC: F04B27/14
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To open/close a high pressure valve part by small force by drivingly opening/closing a pilot valve part by an electromagnetic solenoid valve wherein the aforesaid pilot valve whose effective pressure bearing area is narrower than that of a high pressure valve part opening/closing a communication path between a crank room and a high pressure discharge chamber. SOLUTION: The hole diameter of a pilot valve part 48 is made slenderer by far than that of a high pressure valve part 36, and as for an effective pressure bearing area proportional to the second power of a hole diameter, the pilot valve part 48 is smaller by far than the high pressure valve part 36. In addition, a driving bar 49 transferring the movement of an electromagnetic solenoid 50 to a ball valve 47, is loosely fitted in the inside of a hole bored at the axial line position of an operating bar 35, so that coolant can pass through a gap between the outer circumference of the driving bar 49 and the inner circumference of the hole of the operating bar 35. Since the effective pressure bearing area of the pilot valve part 48 is very small as compared with that of the high pressure valve part 36, the pilot valve part 48 can thereby be opened by small driving force, therefore, the heating value of the electromagnetic solenoid 50 is very small.

Abstract: PURPOSE:To obviate a displaying part for displaying a mode within an indoor device and enable a confirmation of an operation mode to be easily performed by a method wherein the indoor device is provided with a window in such a way as the window may oppositely face against a liquid crystal displaying part of a remote controller while the remote controller is stored in the indoor device. CONSTITUTION:An indoor device 1 is formed with a slide window 4. The slide window 4 is slid upwardly when a remote controller 2 is inserted. A liquid crystal displaying part 3 of the remote controller 2 can be seen. With such an arrangement, an exclusive mode displaying part is eliminated in the indoor device, resulting in that a complex mode displayed in the remote controller 2 may also be seen at once by checking the indoor device 1. Since a back-light at the liquid crystal displaying part 3 in the remote controller 2 is lit, it can easily be seen even if a room becomes dark. In addition, in the event that the display part is stored in the main body, a displayed content in the remote controller 2 is varied to increment some displayed characters so as to facilitate a seeing of the characters from a far location.
