Title: Method of jointing semiconductor substrates
Inventor: OKABAYASHI OSAMU
IPC: H01L21/304
Filed: 1988-08-22
Abstract: PURPOSE:To eliminate an insufficient joint state such as a void and facilitate a completely tight joint between substrates over the whole surfaces by a method wherein, when the mirror-polished surfaces of the substrate to be jointed are brought into contact with each other and/or when the substrates are subjected to a thermal treatment after that, ultrasonic vibrations are applied to the substrates to be jointed. CONSTITUTION:Ultrasonic oscillators 22 are connected to ultrasonic piezoelectric transducers 18 provided outside a pair of quartz blocks 16 holding a plurality of silicon semiconductor substrates 14 so as to apply ultrasonic vibrations to the ultrasonic piezoelectric transducers 18. By making left and right stainless steel rods 24 protrude into a chamber 10 so as to push the ultrasonic piezoelectric transducers 18 and then subjecting the substrates 14 by heaters 12, the diffusion and reorganization of the component element of the substrate material near the substrate surface is accelerated. By applying the ultrasonic vibration to the substrate 14 as described above, an insufficient joint state such as a void can be eliminated and, even if the size of the semiconductor substrate 14 is large, a completely tight joint can be achieved over the whole surface.

Title: Agc circuit
Inventor: ENDO TAKEMI
IPC: H04B10/564
Filed: 1984-10-02
Abstract: PURPOSE:To obtain an optimum S/N to an optical power by feeding back a prescribed value to an avalanche photodiode APD and its output amplifier from the amplifier output to control the gain of the APD and the amplifier differently. CONSTITUTION:The output of the APD1 receiving an optical signal is amplified by an amplifier 2, and a peak value of the output of the amplifier 2 is detected by a peak detector 3. The gain of the amplifier 2 is controlled so as to be inversely proportional to io<(1+x)/(2+x)> at a control amplifier 5 by using a detection signal of the detector 3, where i0 is an optical input current of the APD1 and (x) is an excess noise figure of the APD1 and the multiple factor of the APD1 is controlled so as to be inversely proportional to i0<1/(2+x)> at a control amplifier 4. Thus, the optocal reception amplifier circuit is controlled with the optimum S/N of optical receiving power.

Title: Method for low-temperature and high- pressure vapor deposition of wafer
Inventor: ISURAERU BEINGURASU
IPC: C23C16/24
Filed: 1992-08-03
Abstract: PURPOSE: To improve processing quantity of the vapor deposition of silicon on a single substrate by mounting the substrate in a vacuum chamber, controlling the temperature of the substrate between the temperature having specified values and adding a silicon precursor material gas under a pressure between teh specified values until the silicon layer having a desired thickness is obtained. CONSTITUTION: In order to improve the vapor-deposition speed of doped silicon or silicon that is not doped, the pressure in a chamber is maintained at about 10-350Torr. The accurate crystallographic property of the silicon depends on the temperature of the vapor deposition. In the process of forming a silicon layer that is not doped on a silicon wafer, hydrogen is fed into a chamber, and silane is added after the wafer temperature has reaches a value between 600 deg.C and 750 deg.C. Thus, the pressure between about 10Torr and 350Torr is maintained in the vacuum chamber. In this way, the mixture of polycrystalline silicon and amorphous silicon undergoes vapor deposition at a speed of 2,000Å minute.

IPC: B62D33/07
Filed: 1983-11-04
Abstract: PURPOSE:To prevent a cab from being subjected to impact upon abrupt forward tilting, by providing such an arrangement that an engaging part which swings and approaches so as to engage with the shaft part of a coupling part between a lost motion arm and the front end of a rod in association with the tilting of the cab by a predetermined angle.

In this condition a lock arm 11 is spaced from a pin 8 in its abutting position. When the piston rod 6 extends further so that the tilting of the cab 1 about cab tilt center P as a fulcrum is started, the lock arm 11 swings relatively toward the pin 8 and approaches the pin 8, and is therefore engaged with the pin 8 before the gravitational center moves beyond the center P.
