Title: Manufacture of non-volatile semiconductor memory device
Inventor: FUJIKAWA KOJI
IPC: H01L29/792
Filed: 1991-07-25
Abstract: PURPOSE:To reduce the area of a device, by forming a floating gate and an active region in a self-alignment process without requiring a marginal space for alignment. CONSTITUTION:A gate oxide film 32 and a tunnel oxide film 34 are formed on the surface of a p-type silicon semiconductor substrate 31. First polysilicon 35, an oxide film 36, and a nitride film 37 are grown over the face of the substrate 31. On the nitride film 37, a resist pattern 38 is formed so that an active region of the substrate 31 is covered with the resist pattern 38. The resist pattern 38 is used as a mask to etch the nitride film 37, the oxide film 36, and the first polysilicon 35 so that a nitride film pattern 37a is formed as an anti- oxidation mask. The first polysilicon 35 is patterned on the same pattern. The resist pattern 38 is removed. Then, the substrate 31 is oxidized selectively with the nitride film pattern 37a used as to mask so as to form a thick field oxide film and divide the substrate 31 into two regions, i.e., a field region and an active region 41.

Title: Measuring method for spiral spring torque
Inventor: ITO YUKIO
IPC: G01L3/00
Filed: 1985-09-19
Abstract: PURPOSE:To measure a time-elapsed torque variation of a spiral spring from an output voltage from a torque converter and a variation value of a rotational angle of a motor, by executing the winding and rewinding to the spiral spring by the motor whose rotation is controlled. CONSTITUTION:By a motor start signal, a motor 18 winds up a spiral spring 14. An output voltage of a torque converter 12 connected to an output side of the spiral spring 14 is inputted to a CPU 28. Also, as the motor 18 rotates, a pulse of a rotary encoder 20 is inputted to the CPU 28 as a rotational angle of the motor 18. When the spiral spring 24 reaches a prescribed number of times of winding, a reverse rotation command is outputted to the motor 18, and rewinding of the spiral spring 14 is executed. When the rotation of the motor 18 stops, the CPU 28 starts an operation based on a torque variation value which is inputted and stored in the process of winding and rewinding of the spiral spring 14, and a data of the rotational angle of the motor 18. In such a way, a variation of an output torque corresponding to a variation of the rotational angle can be measured quickly in a short period, and also the measurement can be executed continuously.

Filed: 1994-08-31
Abstract: PURPOSE: To enhance the purity of the gas adsorbed on an adsorbent by providing expansible elements increased and decreased in vol. corresponding to the pressure of gas to a gas introducing part and a gas purifying part. CONSTITUTION: Mixed gas is introduced into an adsorbing tank 4 and A-gas being an easily adsorbable component is adsorbed by an adsorbent and B-gas being the remaining hardly adsorbable component is extracted. Next, in the process before a pressure reducing process, the pressure in the adsorbing tank 4 drops with the elapse of time because a gas inlet valve 10 is closed and a gas outlet valve 12 is opened. Therefore, contracted expansible elements 5 are expanded (restored) in the gas introducing part 1. As a result, the mixed gas remaining in the gas introducing part 1 moves to an adsorbing part 2 and the A-gas is adsorbed while the residual B-gas moves to a gas purifying part 3. Even in the gas purifying part 3, the expansible elements 5 are expanded (restored) and the residual B-gas is discharged to the outside of the tank 4 from a purified gas outlet 9.  Next, evacuation is performed to obtain the A-gas discharged from the adsorbent as high purity gas.

Title: Ambient temperature correction unit for infrared camera
Inventor: SAKAMOTO MINORU
IPC: G01J5/10
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To correct the thermal effect of ambient temperature on the optical system of an infrared camera. SOLUTION: Infrared rays radiated from an object 1 passes through an optical system comprising a lens 2, an iris 3 and a lens barrel 4 and enters an infrared sensor 5. A temperature sensor 6 measures the temperature of optical system. A thermal energy operating section 7 converts a measured temperature value into thermal energy of the optical system. A subtracting section 8 subtracts the thermal energy of the optical system from the thermal energy obtained from the sensor 5 thus finding only the thermal energy radiated from the object 1 regardless of the ambient temperature. A temperature value converting section 9 converts thermal energy from the subtracting section 8 into temperature value. An image processing section 10 converts output from the temperature value converting section 9 into image signal which is then delivered to a display section 11.

Title: Storing method for continuous fiber bundle
Inventor: URANO TSUTOMU
IPC: B65H54/78
Filed: 1981-12-25
Abstract: PURPOSE:To enable a fiber bundle to be stored in a vessel in compact status without suspending the feeding of the fiber bundle, when the fiber bundle is stored into the vessel, by giving drop impacts arbitrary times to the storing vessel at any time during the storing work. CONSTITUTION:Two (fiber bundle) 1 is continuously supplied through a feeding roller and a twilling funnel both of which are not illustrated, and is stacked up gradually, making twilling motion widthwise and lengthwise in a storing vessel 2. The storing vessel 2 is conveyed by a conveyor 3 to be stopped at a prescribed position, while the storing work of the tow 1 is carried out in this state. When a suitable amount of tow 1 is stacked in the vessel 2, the vessel 2 is heaved up to a suitable height by the operation of an air cylinder 4. Next, the abrupt releasing of the air pressure in the air cylinder 4 drops the vessel 2. Thus the impact imposed vertically to the tow 1 makes the tow 1 to be stacked in compact status.

When the thermal output of the head is increased, the ink material 120 starts being melted, and is transferred through penetration. Accordingly, the hot-melt material ensures smooth and effective penetration and transfer of the molten ink material.
