Patent JP-S62120085-A (JP)
Title: Manufacture of semiconductor device
Inventor: NOZAKI TSUTOMU
IPC: H01L29/866
Filed: 1985-11-20
Abstract: PURPOSE:To decrease the variation in Zener voltage, by manufacturing a semiconductor device through the steps of providing a P-type first region on an N-type semiconductor substrate; forming an N<+> type second region within the first region; providing a surface-exposed section around the junction region between the first and second regions; and newly forming a thermally oxidized film in the surface-exposed section. CONSTITUTION:An N<-> type epitaxial layer 2 is deposited on an N<+> type substrate 1. Using a silicon oxide film 3 on the surface thereof as a mask, boron is diffused to form a P-type first region 4. Similarly using the oxide film 3 as a mask, phosphorus is diffused to form an N<+> type second region 5 within the first region 4 (a). After the substrate 2 is entirely covered with a protection film 6 for preventing invasion of impurities, an aperture is provided in a junction region between the regions 4 and 5 and a region near there by means of etching so as to expose the surface of the substrate 2. A thermally oxidized film 7 is newly formed in the aperture (b). Thereby, the boron is drawn into the film 7 and the impurity concentration on the surface of the substrate 2 is decreased. As a result, no break-down occurs on the surface thereof. Further, since possible breakdown occurs at a deep region, no charge is exchanged between such region and the silicon oxide 3 and, therefore, the variation in Zener voltage can be decreased. Finally, the oxide film 3 is etched to provide an aperture and an electrode 8 is provided therein (c).

Title: Combustion type heating apparatus
Inventor: ISHIDA KAZUHARU
IPC: F23N5/10
Filed: 1987-10-15
Abstract: PURPOSE:To avoid giving unpleasant feeling to users by a method wherein when the interior of a room is cold at the primary stage of ignition, quick heating which makes a burning amount at a burner larger than its rated burning amount is carried out for a predetermined period of time, and when the indoor temperature rises, the quick heating is stopped. CONSTITUTION:When a room temperature which a room temperature detecting means 33 detects is lower, at the primary stage of ignition, than a quick heating start temperature lower than a preset temperature, i.e. a first preset temperature, for example, 5 deg.C, which is set by a room temperature setting means 32, the burning amount of gas at a burner 15 is increased by ten-odd percent over a rated burning amount by means of the operation of a burning amount control unit 30, within a predetermined period of time at the primary stage of ignition and until the room temperature which the room temperature detecting means 33 detects reaches a quick heating stop temperature, i.e. a second preset temperature, which is, for example, 3 deg.C higher than the quick heating start temperature. As a result, in the case where the interior of a room is cold at the primary stage of ignition, the quick heating in the interior of the room is carried out in the burning amount larger than the rated burning amount to enable the interior of the room to be quickly warmed up. Thereafter, when the indoor temperature is elevated by means of the quick heating to the level of the quick heating stop temperature, the quick heating is stopped, so that a feeling of unpleasantness is not given to users.

Title: Method for separating and refining hydrogen by using hydrogen occlusion alloy slurry
Inventor: MORIMOTO SHIMIZU
IPC: C01B3/56
Filed: 1991-10-08
Abstract: PURPOSE:To provide the method for separating and refining hydrogen by using a hydrogen occlusion alloy which has good thermal efficiency and can recover high-purity hydrogen. CONSTITUTION:A slurry 8 is circulated between an occlusion tank 1 and a release tank 2. A hydrogen-contg. gas 9 is introduced into the occlusion tank 1 and the hydrogen is occluded by the slurry 8. The slurry itself is heated up by the quantity of the heat generated at this time to prepare the high-temp. and high-pressure slurry. This high-temp. and high-pressure slurry is reduced in pressure by a reducing valve 3 to form the high-temp. and low-pressure slurry which is then transferred into the release tank 2. The high-temp. and low-pressure slurry 8 transferred into the release tank 2 releases the hydrogen 10. The temp. of the slurry 8 is lowered by the absorption of the heat according to the release of the hydrogen at this time to form the low-temp. and low- pressure slurry. This low-temp. and low-pressure slurry 8 is pressurized by a slurry pump 5 to form the low-temp. and high-pressure slurry. This slurry is recirculated to the occlusion tank 1 and, thereafter, the occlusion and release of the hydrogen are repeated.

Title: Recording circuit for magnetic recording device
Inventor: ISHIDA SUMI
IPC: G11B5/09
Filed: 1990-09-28
Abstract: PURPOSE:To prevent the waviness of the envelope of a recording current by supplying the recording current to a recording head by summing a current selected and outputted according to a digital signal to be recorded and the current obtained by multiplying the total of the current values of all DC current sources excepting the selected current by a prescribed number. CONSTITUTION:In the case that a switch 37 is selected, the current pulse of amplitude I1 flows in the collector of a transistor Tr 41 according to the waveform of a recording signal inputted to a terminal 42, and the DC current of (I2+I3)/2 flows in the collector of the Tr 36. Accordingly, the mean current of the collector current of the Tr 44 becomes (I1+I2+I3)/2, and the collector current of the Tr 45 becomes m.I1 in its amplitude and m(I1+I2+I3)/2 in its mean current. Similarly, in the case that the switch 38 or the switch 39 is selected, since the mean collector current of the Tr 45 is m(I1+I2+I3)/2 and constant in both cases, no waviness is caused in the envelope of the recording current even if the recording current is changed.

Title: Pipeline repairing method
Inventor: OOTSUKA KATSUNORI
IPC: F16L1/00
Filed: 1992-09-30
Abstract: PURPOSE:To turn over a thick repairing material smoothly and prevent the generation of environmental destruction by the turning-over by positioning the level of liquid above a bending section of a bending pipe and adding vegetable oil to the liquid. CONSTITUTION:A second liner component 12 is guided to the end of a drain pipe 1 on the inner side of a bending pipe 15 connected with the rear end of a fixed pipe 16. Liquid L is filled in a space formed by the above arrangement to insert the second liner component 12 into the inside of the drain pipe 1, and its liquid level 18 is positioned above a bending section 15a of the bending pipe 15. A small amount of vegetable oil is added to the liquid L. As a result, head pressure is applied to a turning-over section 12b of the second liner component 12, and fitting is carried out. In this case, as the contact section 21 of the bending pipe 15 is positioned higher than the drain pipe 1, the majority of vegetable oil remains in the contact section 21 because of gravity to reduce effectively the friction between the second liner component 12 and the inner wall face of the bending pipe 15 at the contact section 21.

The train detection point is set previously in a controller 6 on the train and when the train head part reaches the point, an elapsed time and the frequency of writing are recorded in the recording table 7 of said device at constant intervals of distance from said arrival point as the train moves. When the measured time sent on the ground is received, the value of the elapsed time which is closest to the received time is selected in the table 7 and the frequency of writing corresponding to it is multiplied by the constant distance to find a movement distance, which is set and recorded as the train length L.

IPC: G02B6/00
Filed: 1991-10-09
Abstract: PURPOSE:To enable high-speed operation and operation with low-power by setting the wavelength of control light in the abnormal dispersion area of a nonlinear optical medium. CONSTITUTION:Unless the control light is made incident on a control light incidence terminal 13b, signal light which is made incident from a signal light incidence terminal 13a is returned to a signal light incidence terminal 13 by an interferometer consisting of an optical fiber 16 and a PANDA fiber coupler 15.
