Title: Production of aln substrate
Inventor: KAWABATA KEIJI
IPC: C04B35/638
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To burn an AlN substrate little in a warpage by using an AlN green substrate formed of an AlN green sheet. SOLUTION: Carrier films are peeled from two sheets of aluminum nitride (AlN) green sheets formed into tapes and thereafter the slick faces (film-peeling faces) of both AlN green sheets are mutually overlapped. While the slick faces are heated e.g. at 120 deg.C, these are pressed at 0.08 t/cm<2> pressing pressure. The slick faces of both AlN green sheets are thermally contact-bonded and laminated. The laminate is punched into a prescribed shape and an AlN green substrate is produced. Thereafter, the AlN green substrate is heated for 15 minutes at such temperature (e.g. 80 deg.C) that an organic binder contained therein is not thermally decomposed. Then, the AlN green substrate is pressed e.g. at 0.021 t/cm<2> to straighten the warpage (green warpage) of the AlN green substrate.  Thereafter, the AlN green substrate is degreased and then burned at 1700-1800 deg.C in the nitrogen atmosphere.

Abstract: PURPOSE:To eliminate demand for strict size precision of a shaft part and a bearing part by providing the bearing part on the mirror housing side to the shaft part further on the diametrically outer side of the outer circumference of a support shaft. CONSTITUTION:A stay holder 25 is provided around a support shaft 3. Because the mirror housing 35 side of it is rotatably supported by a base plate 27 of this stay holder 25, a bearing part 41 on the mirror housing 35 side is diametrically outward apart from the outer circumference of the support shaft 3. Compared to devices in which the bearing part is directly engaged with the outer circumference of the support shaft, therefore, a support point on the mirror housing 35 side is deflected to be on the diametrically outer side of the support shaft 3. Rattling on the forward end side of the mirror housing 35 can thus be restricted.

Title: Push-pull amplifier
Inventor: OOYAMA AKIHIRO
IPC: H03F3/30
Filed: 1986-03-27
Abstract: PURPOSE:To surely prevent destruction of an output transistor (TR) at grounding or short-circuit by connecting a switch to the 2nd TR and controlling the switching by a comparator comparing a potential at an output terminal and a power voltage. CONSTITUTION:When a potential at the output terminal 2 is lower than a setting voltage V9 of a voltage source 9 at grounding, a switch 10 is turned off by the operation of a comparator 8 to interrupt the collector current of a TR 5. Thus, the collector current of a TR 3 whose base is connected to the emitter of the TR 5 is interrupted. On the other hand, the circuit is operated similarly at short-circuit as grounding and let the setting voltage of the voltage source 12 be V12, then the maximum voltage VCE when a large current flows to the collector of a TR 4 is expressed as VCE=Vcc-V12, where Vcc is the power voltage. Thus, no large current flows to the TRs 3,4 and no destruction is caused to them.

Abstract: PURPOSE:To prevent securely and inexpensively a noncondensable gas from flowing back from a tank to the condenser side, by issuing a control signal for closing a valve after a predetermined lapse of time from reception of a stop signal from a burner. CONSTITUTION:A controller C supplied with an OFF signal from a thermoswitch SG or a full closure signal from a valve VF through a timer T1 leaves a solenoid valve V in a bleed pipeline 37 open until a predetermined period of 3m elapses. Noncondensable gas flowing from a heater 28 into a condenser 3 is bled into a tank T. Noncondensable gas rapidly librated from outer walls of heat transfer tubes of a cooler 29 is also bled similarly. With combustion at a burner 25 stopped, the refrigeration output of an absorption refrigerator is rapidly lowered, and the temperature of a cold water starts to rise, and when the cold water temperature on the outlet side of a heat exchanger 30 is raised to a preset upper limit of 8 deg.C, a thermoswitch SC is turned ON, and the combustion at the burner 25 is started. The solenoid valve V is immediately switched from the closed state to the open state. The noncondensable gases collecting into the cooler 29 of the condenser 3 together with a flow of a refrigerant vapor are again bled into the tank T.

Filed: 1980-05-26
Abstract: PURPOSE: To reduce backlash and a lead error, by tread-rolling the screw shaft of a feeder for a numerical-controlled machine tool and connecting a plurality of signal nuts together through a spring washer.  
     CONSTITUTION: A screw shaft 2 is thread-rolled. A first and a second signal nuts 4, 5 are connected together through a spring washer 13 by bolts 12 so that the signal nusts 4, 5 are always energized towards each other. When the screw shaft 2 is rotated in a direction X, a slide table 17 is moved in the axial direction X' of the shaft 2 through the signal nuts 4, 5 and a ball not shown in the drawing. When lod fluctuation has occurred during the movement of the slide table 17, the spring washer 13 is elastically deformed to absorb the load fluctuation. This results in reducing backlash and maintaining an accurate feed speed. The load fluctuation is thus flexibly coped with.
