Abstract: PURPOSE:To improve cell characteristics when a semiconductor device is used for an EPROM cell by increasing the withstanding voltage of an oxide film formed onto the surface of a polycrystalline silicon film. CONSTITUTION:A foundation oxide film 12 and a polycrystalline silicon film 13 are deposited on the surface of an N-type silicon substrate 11, and phosphorus is diffused for 15min at 950 deg.C in a POCl3 atmosphere, thus bringing phosphorus concentration in the polycrystalline silicon film 13 to 1X10<20>cm<-3>. A PSG film (a phosphorus-doped oxide film) 14 having phosphorus concentration of 1X10<21>cm<-3> is deposited on the whole surface through a CVD method, and annealed for 30min at 950 deg.C in a N2 atmosphere. The PSG film 14 is removed through dipping for 1min in NH4F, and a polycrystalline silicon oxide film 15 is formed onto the surface of the polycrystalline silicon film 13 through dry oxidation.

Title: Isothermal control type calorimeter
Inventor: KOMIYAMA MAKOTO
IPC: G01J1/02
Filed: 1991-03-29
Abstract: PURPOSE:To enable measurement to be made in a state that a light receiving body is not increased in temperature by assuming isothermal control while the differential signals of temperature difference detection signals are being referred, which are obtained from the respective temperature difference detection elements at the light receiving side and a temperature reference means side. CONSTITUTION:Both temperature difference detection elements 6a and 6b installed onto a light receiving body 1 with a heater, and temperature difference detection elements 32a and 32b installed onto a temperature reference means 31 which is to be a reference for measured temperature, are differentially amplified in output in a state that gain is variable by means of a variable gain differential amplifier 33. The differentially amplified output is applied to a PID amplifier 14, so that heater power for isothermal control is thereby determined by means of specified PID operations. Electric power for the heater is so controlled that both the reference means 31 and the light receiving body 1 are in a equilibrium condition in a state that a shutter is closed first, and then the shutter is opened. Electric power consumed by the heater in the respective cases is represented by PH1 and PH2. The power PL of incident light La is substituted by the difference in electric power, that is, PH1-PH2, the power PL can therefore be determined by obtaining both PH1 and PH2.

Title: Air bag device
Inventor: URUFU MATSUTE
IPC: B60R21/20
Filed: 1994-04-05
Abstract: PURPOSE: To provide an airbag device which can be incorporated into an existing instrument panel at a low cost. CONSTITUTION: A fastening means for support 3 holds this airbag device along a vehicle instrument panel and within an open trough-shaped body 16 located within the panel. A casing part is formed by a cover 12 held on the support 3. The outer contour of the cover 12 fits the geometrical shape of the trough- shaped body in order to insert the airbag device into the trough-shaped body (glove compartment) 16. Thus, since the cover covering the airbag device fits the contour of the storage trough-shaped body, the entire airbag device harmonizes with and fits the entire vehicle instrument panel. A production process for existing instrument panels continuously produced does not need to be changed, and simple mounting of screws in through holes and insertion of the airbag device need to be added for installation. A high level of safety can be achieved even for small vehicles.  The instrument panel which usually remains undamaged after a vehicle accident can be further used.

Title: Centering method of strip material and device thereof
Inventor: SASAKI NAOKI
IPC: G01B11/00
Filed: 1989-03-22
Abstract: PURPOSE:To perform a highly accurate centering and a correction of off-center value by driving a positioner for a turning arm equipped with a holding device as far as the value detected of the off-center value of a strip material by an optical detecting means. CONSTITUTION:When a strip material W on a belt conveyor 1 is off-centered from the midway, this off-center value is detected. In brief, each light receiving value of plural numbers of a light emitter 2a and a light receiver 2b is compared with a light receiving value of the strip material W in a centering state, thus the off-center value is detected. Next, an air cylinder 9 pressing and holding this strip material W is operated, and the strip material W is held between rollers 6a and 6b. When this off-center value is converted into a pulse signal and a linear pulse motor 11 is driven, centering for the strip material W is automatically performed irrespective of material thickness by rotation of an arm 7 conformed to the offset value.
