Title: Manufacture of semiconductor pressure transducer
Inventor: OHASHI SHIGEO
IPC: H01L29/84
Filed: 1986-04-09
Abstract: PURPOSE:To prevent the yielding and the growing of fine cracks in a low melting point glass layer, to keep electric characteristics and airtightness constant and to eliminate time change of the quality of a semiconductor pressure transducer, by printing low melting point glass having a plurality of thin wire patterns formed in closed concentric shapes on one surface of a pedestral part comprising ceramics and the like, mounting a semiconductor crystal substrate on the low-melting-point-glass printed surface, and performing heat treatment at a temperature, at which the low melting point glass is fused, in a vacuum atmosphere. CONSTITUTION:A pedestal part 2 comprising ceramics and the like is machined in a specified shape. On the surface-to-be-bonded of the pedestal part 2, low melting point glass 3 having thin wire patterns is formed. A plurality of the thin wires are printed by, e.g., a screen printing technology. As the width of said thin wire patterns, a value of about 0.08-1 mm is desirable for effectively absorbing and alleviating stress being yielded. A cavity part (recess part) 4 is formed in the back surface, and a diaphragm part 6 and a supporting part 5 are formed. A semiconductor crystal substrate is overlapped on the surface of the diaphragm part. Loads in the range of 0.1-0.2 kg/cm<2> are applied from both sides. Heat treatment is performed at a temperature higher than the fusing temperature of the low melting point glass in a vacuum atmosphere. Even if the bonding area for the low melting point glass is small, the yield rate is all the more improved without major difference in bonding strength.

Title: Dimming device and lighting system
Inventor: KOBAYASHI MASAYUKI
IPC: H05B37/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To make a circuit compact and inexpensive and reduce production of higher harmonic noises and acoustic noises from an incandescent lamp. SOLUTION: In a timing generating part 7, the zero-cross point of an ac power supply 1 is detected, and an ignition pulse is produced in every half-cycle at the timing corresponding to a dimming level provided through a transmission line 10, to make a LED emit light and to turn a light intercepting element PTH on. Thereby a thyristor 3 is turned on in every half-cycle. Therefore, a full-wave rectification voltage is supplied from a full-wave rectifier circuit 4 to an incandescent lamp 13 in every half-cycle, only for a period corresponding to the dimming level, to achieve dimmed lighting. In this case, an IGBT 5 is gradually turned on by a base control signal from an inclination control part 9 immediately before the rise of the ignition pulse, and therefore the rise of the voltage applied to the incandescent lamp 13 is slowed.  Therefore, dimmed lighting of the incandescent lamp 13 can be achieved only by the phase control of one thyristor 3, and production of higher harmonic noises and acoustic noises from the incandescent lamp can be reduced.

CONSTITUTION:Projections 91A on the outer surface of an endless belt 91 in a tension exerting mechanism 9 pierce and engage in feed holes in both right and left ends of a fun-fold sheet 10 between an exposure drum 1 and a fixing unit 8, and the endless belt 91 is therefore pulled by the fun-fold sheet 10 conveyed in the fixing unit 8 so that the endless belt 91 is circumferentially driven. Due to the circumferential resistance of the endless belt 91, a certain tension (back-tension) is exerted to the fun-fold sheet 10 between the tension exerting mechanism 9 and the fixing unit 8. As a result, the condition of the fun-fold sheet 10 introduced into between a pair of fixing rolls 81 is made to be uniform, thereby it is possible to prevent occurrence of slant movement and meandering of the fun-fold sheet 10.
