Title: Heterojunction element and manufacture thereof
Inventor: AMAMIYA YOSHIHITO
IPC: H01L29/737
Filed: 1987-05-01
Abstract: PURPOSE:To obtain a practical silicon system wide gap material by using amor phous material silicon arsenic consisting of a couple elements of silicon and arsenic as the hetero material for silicon and emitter material for Si-HBT. CONSTITUTION:An amorphous silicon arsenic (a-SiAsx) is mainly fabricated by a reduced-pressure CVD method. As the raw material gas, disilane Si2H6 and arsine AsH3 are used and as the carrier gas, helium He is used. These are guided to a quartz reaction tube for thermal decomposition at 450-500 deg.C and thereby a thin film of a-SiAsx is deposited on a silicon wafer. The a-SiAsx thus formed is of perfect amorphous state. Prior to application of a-SiAsx to the emitter of Si-HBT, a hetero junction diode of a-SiAsx and p type silicon is constituted. A polycrystalline silicon layer 6 is provided to protect a thin a-SiAsx layer 5. For deposition of polycrystalline silicon, temperature is raised to 600 deg.C after formation of a-SiAsx to lower the flow rate of arsine and thereby the polycrystal silicon is directly deposited.

Title: Lapping stool and lapping method
Inventor: OCHIAI YUUJI
IPC: B24B37/12
Filed: 1982-06-28
Abstract: PURPOSE:To remove a sheet plate from a lapping surface plate when the shape of the workpiece is deteriorated after use and to stick a new sheet plate onto the lapping surface plate for renewing, by applying a sheet plate on a reference plate with the use of a liquid so that the lapping surface plate is formed. CONSTITUTION:A lapping surface plate is composed of a rolled steel plate having its top surface subjected to grinding work for obtaining a refernece plate 1, a tin plate 2 used as a sheet plate 2 and ethylalcohl used as a pasting liquid 3. When an alumina ceramics is lapped with the use of diamond abrasive grain having 1mum particle size as lapping abrasive, a working accuracy and nature substantially equal to or even higher than those obtained by conventional lapping surface plate may be obtained. Further, the repair of the lapping surface plate may be made only by replacing the sheet plate 2 to be applied to the reference plate 1, and therefore, the time necessary for the repair may be shortened, thereby the management of the lapping surface plate may be facilitated.

IPC: G01T1/29
Filed: 1985-05-21
Abstract: PURPOSE:To eliminate ripple components of an output signal and to improve the response and controllability of a control circuit by calculating the timer integrated value of an impulsive ionizing current waveform and dividing the time integrated value by the time of each pulse interval by using a dividing circuit. CONSTITUTION:The amount of impulsive output radiated from a radiation generation part 1 is detected by a detecting means (ion chamber) 2 and its detected value is converted by a current voltage converter 4a into a voltage value, which is further converted by a voltage frequency converter 5a into a frequency. Its output pulses are integrated by the 1st integrating counter 6 for every impulse output dosage. On the other hand, a monostable multivibrator 10 generates pulses with specific width on the basis of the reference pulse signal of the radiation generation part 1 and output pulses of a reference oscillator 11 are integrated by the 2nd integrating counter 12 at intervals of the output. Then, the outputs of those two counters 6 and 12 are supplied to the dividing circuit 16 to calculate their difference, thereby obtaining the monitor signal (b) of the radiation output dosage.

Abstract: PURPOSE:To reduce a danger that hands or material trespasses into a scanning range by providing a material detecting means for detecting the access of the material into the scanning range of the lens scanner and a scanner control means for controlling the lens moving speed to the fine speed. CONSTITUTION:When the drawing operation is started, a motor 12 is driven to move an acoustic lens 4 in the X direction at a high speed, and the sample is scanned in the X direction at the high speed by one line.

Title: Scanning electron microscope
Inventor: FURUYA HISAHIRO
IPC: H01J37/28
Filed: 1985-05-24
Abstract: PURPOSE:To control an excessive electron ray emission, by reducing one or both of DC voltages when the output signal of the sum of both DC voltages exceeds a preset value, in a scanning electron microscope in which DC voltages of different values are applied to the electron ray generating electrode and to the electron ray drawing electrode. CONSTITUTION:When a voltage Va is applied to an electron ray generating electrode 1 from a DC power source 4, while a voltage Vb is applied to an electrode 2 from a DC power source 5, an electron ray drawing voltage to emit electron rays is to apply between the electrodes 1 and 2. The voltages V and Vb are summed up in an addition circuit 9, and the resultant output signal Vc is compared with a standard voltage VR in a comparison circuit 10. If the output signal Vc exceeds the value of the standard voltage VR, either or both of the DC power sources 4 and 5 are controlled to reduce either or both of the voltages Va and Vb. In such a way, an excessive amount of the electron ray emission can be controlled.

Filed: 1977-09-16
Abstract: PURPOSE:To uniformalize the stress distribution at the root of a flange by keeping the length in the axial direction of the thin-walled part at the flange root of a liner sleeve below 2-4 times of the thickness of the liner sleeve. CONSTITUTION:The length in the axial direction of a thin-walled part 11 is shown by l, and the tickness of a liner sleeve 6 is shown by t.

Title: Bar code reader demodulating system
Inventor: MORI GENICHI
IPC: G06K7/10
Filed: 1986-05-16
Abstract: PURPOSE:To prevent lowering of reading rate by making shifting for two of black data and white data successively until start code is found and demodulating from next black data when the start code is impossible to read because a spot before start code is read. CONSTITUTION:When a start code (a) is impossible to read because a spot 31 is read, shifting for two of black data and white data is made and demodulation is made from next black data and the start code a is read. For instance, when a spot 31 before the first black bar is read as a black bar, and consequently the start code can not be read, one black bar is shifted and demodulation is made from next black bar. However, as the black bar is the first genuine bar of the start code, it means that the start code is read accurately, and time for another scanning can be saved.

Abstract: PURPOSE: To reduce the number of parts used in a non-contacting power distribution system so as to provide an inexpensive constant-current source by supplying a constant voltage outputted from a constant-voltage power source to feeder lines after the constant voltage is converted into a constant current by means of an impedance converting section. CONSTITUTION: In a monorail type carrying facility which feeds electricity to a plurality of loads, such as carriers, etc., through each pickup section inductively coupled with each feeder line, a power source section is constituted by combining an constant-voltage power source 31 with an impedance converting section 32 so that the power source section can supply a constant current to the loads. The impedance converting section 32 is constituted by using T-type four-terminal circuits and the section 32 is set so that two inductors Ls 32a and Lr 32a forming the series elements constituting the section 32 can create a resonating state together with a capacitor Cs 32c forming the parallel element of the section 32. Therefore, the constitution of a constant-current source which can always supply a constant current to the feeder lines and can stably supply electric power to each load can be simplified.

Abstract: PURPOSE:To make difficult the deviation of an optical axis with a temp. change by forming at least part of one of a holder, connecting member and head body frame of a ceramic material or an insulating org. material having a low coefft. of thermal expansion. CONSTITUTION:The holder 54 is formed of the ceramic member or the org. insulating material having the low coefft. of thermal expansion.
