Title: Solid laser equipment
Inventor: TERADA MITSUGI
IPC: H01S3/094
Filed: 1992-05-25
Abstract: PURPOSE:To amplify only the laser light of specified light emission duration and repetition frequency, and enable the high repetition output of laser light having short light emission duration and large power, by combining a solid laser equipment for oscillation with a solid laser equipment for amplification. CONSTITUTION:When light energy enters a solid laser rod 1 for oscillation in a solid laser equipment part for oscillation, laser light to be amplified whose output is 1W or smaller, whose light emission duration is 100nsec or shorter, and whose repetition frequency is 10kHz or higher is outputted, in virtue of the amplifying action of a resonator and the controlling action of an A/O-Q switch 3 for the Q-value of the resonator. When the laser light for pumping whose light energy is small, whose light emission duration is short, and whose repetition frequency is high enters a solid laser rod 8 for amplification in a solid laser equipment for amplification, the laser rod 8 is sinchronously turned into the excited state, and the laser for pumping is amplified. Thereby the light energy is increased while the light emission duration is kept almost constant.

When the data become greater than the preset value, a specified film thickness is secured, the breaker is stopped, and the current application to the electrodes 7-9 is stopped. The current application and breaker control are carried out for each unit of the electrodes 7-9.

IPC: G06F9/46
Filed: 1992-05-26
Abstract: PURPOSE:To shorten the resources occupying time and to improve the working efficiency of a computer system which operates with plural programs by evading such a case where the resources are occupied by the program operating by a general-purpose computer for the entire time required for execution of the program. CONSTITUTION:When a program starts, the contents of an input file 30 to be originally used are converted into an intermediate file 60 in terms of a medium by a 1st medium conversion mechanism 27. At the same time, the relationships between the file 30, the file 40, an output file 70, and an intermediate output file 50 are controlled by a resources using state control file 60. In a program execution mode, these relationships are inputted from the file 40 and outputted to the file 50. When the program ends, an end mechanism 26 converts the contents of the file 50 into the file 70 in terms of a medium through a 2nd medium conversion mechanism 28 and then erases the contents of the file 60 to complete the due processing. In such a constitution, it is just required to concentrically occupy both files 30 and 70 only when the program starts and ends.

Filed: 1995-05-31
Abstract: PURPOSE: To eliminate the effect on the performance of an antenna such as radiation pattern or directivity when electronic components are arranged on a flip of the portable radio equipment. CONSTITUTION: A length of a lead wire 3 of an electronic component 2 toward ground is selected to be λ/2 (λ is a wavelength with respect to an operating frequency) so that the ground side of the lead wire 3 of the electronic component 2 is set open when viewed from a radio equipment main body 4 is kept open.

Title: Noise resistance improving circuit for amplifier
Inventor: HATSUTORI YOSHIKUNI
IPC: H03F3/60
Filed: 1994-06-16
Abstract: PURPOSE:To improve the noise resistance of an amplifier. CONSTITUTION:This circuit has transmission lines 9 and 11 connected to input terminals 3 and 5 of a differential amplifier 1 and a capacitor 13 connected between transmission lines 9 and 11, and the lengthes of transmission lines 9 and 11 from terminals 13a and 13b of the capacitor 13 to input terminals 3 and 5 of the differential amplifier 1 are made equal to each other. Since the high frequency noise penetrating one transmission line passes through the capacitor 13 and is equally superposed on both of transmission lines 9 and 11, the influence of the noise upon the differential amplifier 1 is cancelled.

Title: Ultrasonic method for detecting flaw in laser beam and electron beam welded joint
Inventor: MATSUMOTO TAIICHI
IPC: G01N29/04
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic method for detecting flaws in a laser beam and electron beam welded joint capable of accurately inspecting a defect in the root part of a welded part with a narrow bead width by suppressing the effects of penetration echoes from a penetration bead. SOLUTION: The back surface of one member to be welded P is protruded to the back side more than the back surface of the other member to be welded P, and welding is performed in this state. Ultrasonic flaw detection is performed from above the surface of the other member to be welded P through the use of a pulse reflected angle beam method. In this case, as an interface directed in a direction to reflect ultrasonic waves as before is hardly formed in a penetration bead 4 formed in a welded part 2, it is possible to suppress the occurrence of penetration echoes substantially.

Title: Method for removing core
Inventor: NISHIDA MASAFUMI
IPC: B22D29/00
Filed: 1989-05-26
Abstract: PURPOSE:To omit core sand burning process by controlling supply of oxygen- containing gas so that core temp. comes to in the prescribed temp. range at the time of burning organic binder by supplying the oxygen-containing gas to the core before opening dies after casting. CONSTITUTION:Molten Al alloy having the prescribed temp. is poured from a sprue 3. The molten metal flows into a product part 4 formed with the dies 2 and core 1 and fills up. At the time of filling up the sprue with the molten metal, the pouring is stopped and the molten metal is solidified in the dies 2. Air as the oxygen-containing gas is blown into the core in the dies 2 from a blowing hole 5 at the prescribed pressure as shown with the arrow mark. The air is discharged to out of the dies from exhaust hole 6 while burning the organic binder in the core 1 already heated. The value set with pre-test is inputted in a timer 7 and based on this value, a solenoid valve 8 is opened/ closed. The core temp. does not exceed the solidified temp. of Al alloy and the organic binder is sufficiently burnt. By this method, the core can be easily removed without developing deflective casting product.

Title: Package for film patrone container
Inventor: KUMAGAI ZENE
IPC: B65D77/30
Filed: 1977-11-09
Abstract: PURPOSE: To facilitate the take-out of film and to evacuate a sealed film patrone container thereby to elongate its effective term by covering the container with a thermally shrinking synthetic resin sheet and by perforating the sheet.  
     CONSTITUTION: The molding 3 outside of the container 1 of thin metal is made of a thermally shrinking synthetic resin sheet and has its upper and lower ends opened, as shown. since the molding 3 covers the cap 2 of the container, there is no fear of returning the pressure in the container, which is either evacuated or is held under a low oxygen partial pressure, to the atmospheric pressure so that the intension of elongating the effective term of the film is lost. since, moreover, the molding 3 is formed with perforations 4 and 5, it is sufficient to break the upper portion of the molding along the perforations when the film patrone is to be taken out.

Title: Voice synthesizer
Inventor: SHIMATANI KEISUKE
IPC: G10L13/00
Filed: 1989-05-26
Abstract: PURPOSE:To enable communication processing during the reproduction of a voice by providing a voice interrupt signal with priority to a communication interrupt signal. CONSTITUTION:When a voice reproduction indication is received during the execution of a main program 1, an interrupt signal for voice reproduction is generated and the control is passed to a voice reproduction interrupt program 2. If there is a request for communication processing between voice reproduction and voice reproduction, the control is transferred to a communication interrupt program 3, but when a voice reproduction indication is received at this time, the hardware of a microcomputer sets the interrupt level of voice reproduction higher than a communication interrupt level, so the communication processing is interrupted temporarily and the voice reproduction is started. A return to the interrupted communication processing is made after the voice reproduction. Consequently, a voice can be reproduced without any break and the communication processing is also performed.
