Title: Manufacture of semiconductor device
Inventor: FUKUDA TAKESHI
IPC: H01L21/762
Filed: 1981-12-14
Abstract: PURPOSE:To allow the formation of an element isolation structure in a simple process, by constituting the isolation structure of an oxide film and a p type Si region left at the bottom of a V-groove. CONSTITUTION:Over the entire surface of a p type Si semiconductor substrate 1, an n type impurity is injected at high density resulting in the formation of an n<+>b region 2. Using dichlorosilane as reaction gas, a p type epitaxial layer 4 is grown over the entire surface on the substrate. This epitaxial growth using dichlorosilane has a large growing speed on a V-groove, and accordingly the surface of the epitaxial layer 4 turns into a gentle surface even on the V-groove. Over the entire surface, an Si3N4 film 5, as an oxidation resisting film, is formed and removed on the V-groove, and then the epitaxial layer 4 on the V-groove is oxidized in oxidizing atmosphere. Even when the epitaxial layer 4 is oxidized from the surface down to the n<+>b region 2, a p type Si region 4' is left at the bottom. After removing the Si3N4 film 5, various kind of elements are formed on the region surrounded by an oxide film 6.

Title: Bell driving circuit
Inventor: HANANO NAOMASA
IPC: H04M3/02
Filed: 1981-12-15
Abstract: PURPOSE:To miniaturize a device, by inverting the polarity of a power supply with the signal of a specific frequecy to obtaon a driving source of a specific frequency which has the voltage double as high as the power supply voltage. CONSTITUTION:Contacts (c) and (d) close for the time T1 when the pulse of 16Hz is positive and opens for the time T2 when the pulse is zero. Thus a current flows to a telephone bell circuit 3 in the direction shown in a figure (B) during the time T1; while a current flows to the circuit 3 in the direction of the figure (B) during the time T2. Therefore 16Hz of the voltage double as high as a power supply V of 48V is applied to the circuit 3. These contacts (c) and (d) are obtained by connecting a pnp transistor TR and an npn TR. On the contrary, contacts (e) and (f) open and close for the time T1 and the time T2, respectively and can be obtained by connecting an non TR and a pnp TR, respectively. As a result, the use of a large-sized transformer for low frequencies can be eliminated.

Title: Load device for simulator
Inventor: SUZAKI SHIRO
IPC: G05F1/10
Filed: 1988-08-12
Abstract: PURPOSE:To rapidly execute simulation by changing a constant constituting a load from a small valve of oscillation to be applied to a system to a required value. CONSTITUTION:The level of voltage to be applied to the load L0 is detected by a voltage detector 1 and a microcomputer 2 controls the connection of a thyrister 3 in accordance with the detected voltage. Namely, the microcomputer 2 changes the conductance G and susceptance B of the load L0 in accordance with the detected voltage. When the ON time of a breaker CB is set up to t=0 e.g., the conductance G and the susceptance B are linearly changed up to respective required values G0, B0 for a fixed timer t1. Consequently, system oscillation can be converged immediately after connecting the load L0 independently of the sizes of the system and the load L0 and simulation can be rapidly executed.

Title: Radio device
Inventor: TATEZUKI KUNIHARU
IPC: H04B1/16
Filed: 1981-12-15
Abstract: PURPOSE:To prevent useless power consumption to save the power consumption while the reception is on stand-by, by varying the start timing of a power supply to a demodulating circuit in response to the detected voltage after detecting the power supply voltage and by shortening the supply time of voltage in case the demodulating circuit has a quick response with a high level of power supply voltage. CONSTITUTION:A radio device is provided with a signal transmitter which transmits call signals for a prescribed period of time from the application of a call switch and a signal receiver which receives intermittently the call signals with a period shorter than the prescribed period of the call signals. A detecting circuit 16 for power supply voltage is connected to a power supply controlling part 15 of the signal receiver to detect the power supply voltage V. Then the reference voltage is compared with the voltage V by a comparator 18 of the circuit 16. When the detected voltage V is low, the start timing is accelerated for the power supply to a demodulating circuit 9 from the controlling part 15. While the start timing is decelerated when the voltage V is high. Thus the useless power consumption is suppressed to save the power consumption while the reception stands ready.

Title: Production of optical recording medium
Inventor: TAMURA KATSUHIDE
IPC: G11B7/26
Filed: 1986-08-30
Abstract: PURPOSE:To produce an optical recording medium having a desired coating thickness and uniformity in a short period by forming a coated film thicker than the final required coating thickness on a substrate, then rotating the substrate to shake off the excess coating liquid. CONSTITUTION:The substrate is set to a spin coater and while the substrate is rotated at a low speed, a brush is brought into contact with the substrate and the coated film is formed thereon in the case of making coating by using the brush. Since the coated film thicker than the final required coating thickness is formed, the coating liquid sticks uniformly over the entire surface of the coating liquid. The coating liquid sticks strongly to the part in contact with the substrate when the substrate is rotated, but the coating liquid is moved and leveled off by centrifugal force in the surface part where adhesive power is weak. The coated film having the uniform coating thickness and coated surface is thus formed.

Abstract: PURPOSE:To minimize a winding amount while maintaining matching accuracy and shorten time required until the start of printing action by arranging paired intermediate rollers which hold a sheet between the sheet feed aperture and the plate part of an automatic sheet feed device equipped with a function for separation/feed process and that for matching process, and driving the intermediate rollers to rotate forward in the matching process. CONSTITUTION:If the drive motor of a printer is rotated forward, sheets P in a hopper 7 are separated and fed by each sheet and proceed to each process such as matching, printing and discharge. An intermediate roller 24 and an auxiliary intermediate roller 25 which comes in contact with the former are arranged between a sheet feed roller 6 and a platen part 12. Then the intermediate roller 24 is driven forward to allow the intermediate part of the sheet to be fed. At the same time, the platen part 12 is driven to rotate backward to allow the tip P14 of the sheet P to be fed back from a specified position on the peripheral surface of the platen part l2. Subsequently, a significant flexible amount can be obtained in a short time between the intermediate roller 24 and the platen part 12. In turn, this elastic force permits the completion of matching between the line of the tip P1 of the sheet P and the tangent of the platen part 12.
