Abstract: PURPOSE:To obtain an element formation layer with a high crystallinity by a method wherein an epitaxial layer is used as a seed for a single crystal and a polycrystalline layer is single-crystallized by a zonemelting method. CONSTITUTION:A silicon dioxide 4 is deposited on a nitride film 2 on a silicon semiconductor substrate 1 by a chemical deposition method. After the silicon dioxide film 4 and the nitride film 2 are patterned, the substrate 1 is subjected to a heat-treatment to form a silicon dioxide film 5 and the silicon nitride film 2 is removed. The silicon dioxide film 5 is etched until a step between the substrate 1 and the silicon dioxide film 5 is leveled and silicon is deposited by a CVD technology to make an epitaxial layer 6 grow on the substrate 1 and to deposit a polycrystalline or amorphous silicon layer 3 on the silicon dioxide film 5. A protective filn 7 of silicon dioxide is deposited on the layer 6 and the layer 3. A neighborhood of the boundary of the layer 6 and layer 3 is heated and melted by a heater and the layer 3 is converted into a single-crystal layer by ascending the heater gradually while the wafer is held inclined to make the seed of a single crystal come to the lower side. With this constitution, a uniform crystal silicon layer with few crystal defects and grain boundaries is obtained.

Filed: 1983-06-24
Abstract: PURPOSE:To increase the efficiency and to reduce the noise of a power source circuit by switching a transistor, converting the output to a sinusoidal wave by a parallel resonator and further returning excess energy to a DC voltage source. CONSTITUTION:When a DC voltage source 10 generates an output voltage, the emitter voltage of a UJT60 rises in response to the time constant determined by a resistor 54 and a capacitor 56. When the emitter voltage reaches the prescribed value, the UJT60 is conducted, the charge charged in the capacitor 56 is discharged, a transistor 28 is conducted, and the UJT60 is interrupted. A circuit which has the transistor 28 as a center starts oscillating, and since a coil 20 and a capacitor 22 are a parallel resonator, a sinusoidal voltage is generated across the coil 20. The energy absorbed by the coil 26 is transmitted to the secondary winding 34, and returned through a reverse blocking diode 36 to the source 10. The nonconducting point of the transistor 28 is controlled by the difference between the output voltage of a rectifying the smoothing circuit 50 and a reference voltage.

Title: Radio data communication equipment
Inventor: KOUNOE TOSHIAKI
IPC: H04N1/32
Filed: 1995-04-17
Abstract: PURPOSE: To prevent interruption of communication due to channel changeover during communication. CONSTITUTION: A controller 1 controls a radio data communication equipment in response to data communication conducted via a radio communication network. When a channel changeover request comes from a base station during data transmission, the controller 1 discriminates whether or not channel changeover is to be conducted based on a transmission status of image information and starts a channel changeover inhibit output means 2 according to the discrimination. The channel changeover inhibit signal output means 2 outputs a channel changeover inhibit signal to the base station. When the transmission of data of a prescribed amount such as one page, one block or one communication is finished, a channel changeover inhibit release signal output means 3 outputs a channel changeover inhibit release signal to a base station according to the end of transmission.  As a result, the base station requests again the channel changeover and the radio data communication equipment conducts channel changeover.

Filed: 1985-05-29
Abstract: PURPOSE:To remove a base valve for separating a process pipe and a meter by installing a means for the transfer of a valve seat part equipped with a snubber in a snubber accommodating chamber. CONSTITUTION:A snubber reduces the pressure pulsation of fluid by the pressure lowering which is generated by allowing fluid to pass through a fine gap which is formed by arranging a pin 5 into a circular hole formed between a process- side pressure introducing pipe 2 and a meter-side pressure introducing pipe 3. An auxiliary valve seat 28 is screwed and fixed through welding onto a valve seat 8. The valve seat 8 is pulled-up by turning-ON a handle 10, and is closely attached onto a seat part 26, and a flow passage 12 can be cut-off. Since the circular hole accommodated into the valve seat 8 is on the connection port side of the process-side pressure introducing pipe 2, the flow passage can be perfectly cut off.

Abstract: PROBLEM TO BE SOLVED: To more efficiently and quickly perform a maintenance measuring work such as disconnection inspection of illuminating lamps, illuminance measurement of various lighting equipments, or the like by loading a lighting detecting photosensor, position detecting optical sensor, and an axle sensor on a measuring. SOLUTION: A lighting detecting photosensor 3, a position detecting optical sensor 4, and an axle sensor 5 are loaded on a measuring vehicle 2. The lighting detecting photosensor 3 measures and automatically judges, from the brightness measurement of various illuminating lamps 1 set within a tunnel, the disconnection position and lamp kind of illuminating lamp, and the lamp life and replacing time thereof.

Title: Inkjet recording head
Inventor: MATSUMOTO HIROZO
IPC: B41J2/045
Filed: 1988-05-11
Abstract: PURPOSE:To improve the responding ability at high speeds in ejecting ink, by adding electric signals to piezoelectric elements respectively corresponding to a main and a sub pressuring chambers, with a shift of timing. CONSTITUTION:When an electric signal is added to a piezoelectric element 23, a vibrating plate 22 where the element 23 is provided displaces inwards of a main ink pressuring chamber 11, thereby to reduce the volume of the chamber 11 suddenly. As a result, ink liquid is ejected outside from a nozzle 21. Thereafter, when the electric signal is removed, the volume of the main ink pressuring chamber 11 is recovered. As the part of the vibrating plate 22 displacing to the main ink pressuring chamber 11 is returned to the original position, the other parts of the plate 22 corresponding to sub ink pressuring chambers 12, 13 are shifted inwards of the chamber 11 with the same timing as the above returning timing, so that the volume of each chamber 12, 13 is reduced. Thus, an extraordinary retreat of a miniscus in the ink nozzle 21 due to the sudden reduction of the volume of the main chamber 11 can be avoided. Accordingly, no troubles result from the suction of air.
