Title: Semiconductor device
Inventor: YAMAMOTO SHIGEJI
IPC: H01L27/06
Filed: 1979-03-02
Abstract: PURPOSE:To enhance the reverse withstand voltage of a semiconductor device and reduce unnecessary capacity thereof by bringing metal and substrate into contact with a Schottky barrier through an insulating film having slow oblique surface on a semiconductor substrate. CONSTITUTION:An n<+>-type layer is buried in a p-type silicon substrate 21, an n- type epitaxial layer 22 is separated with a P layer, the P layer 24 is selectively  formed thereon. An oxide film 26 and a nitride film 27 are used as masks to form  an oxide film 28 and a base layer 29 thereon. At this time a buzz peak occurs to specify an electrode opening. After an opening is selectively formed at the film 28 to  form an n-type emitter layer 30, the nitride film 27 and the oxide film 26 are  removed to form Ti electrodes 31-33. Since the contact portion of the metal forming contact between the epitaxial layer and Schottky barrier with the epitaxial layer  is specified with slow oblique insulating layer, it can restrict unnecessary expansion  of depletion layer to improve the reverse withstand voltage of a semiconductor device and to stabilize the operation of the device. Accordingly, a protection ring is  not necessary to reduce the corresponding capacity so as to enhance the integrity of  the device.

Title: Manufacture of semiconductor device
Inventor: HIRATA SEIICHI
IPC: H01L21/28
Filed: 1984-02-14
Abstract: PURPOSE:To enable the arbitrary control of the specific resistivity of an electrode or a wiring of Al or an Al alloy, by mixing a minute quantity of impurity for forming the Al alloy in an argon ambience when spattering is executed. CONSTITUTION:After the degree of vacuum before Ar replacement is set as high as 1X10<-7>Torr, for instance, the replacement is executed by using an Ar cylinder in which an impurity, e.g. oxygen, for forming an Al alloy is injected in a quantity of several hundreds ppm so as to set the degree of vacuum at about 1X 10<-3>Torr approx., and an Al-Si electrode is formed on a semiconductor substrate through an insulating film by Al-Si spattering and patterning. Thereby the oxygen injected simultaneously with the Ar replacement is made to act with Al atoms in spattering to exist as an oxide such as Al2O3 in an Al-Si film, and thus a film having a large specific resistivity is formed. By controlling the quantity of this oxygen, an Al film having an arbitrary specific resistivity can be obtained.

Title: Tracking servo restoring method
Inventor: KANDA HIDEAKI
IPC: G11B15/467
Filed: 1986-02-06
Abstract: PURPOSE:To decrease the servo recovery time by closing a tracking servo when the synchronizing signal detection level of a track to be traced reaches a prescribed level or above so as to restore a tape feed speed command giving nearly the half speed of the normal reproducing speed to the normal speed. CONSTITUTION:When the synchronizing signal detection level reaches a prescribed level or below, a processing section 19 brings a tape speed command VCMD to nearly a half speed of the tape feeding speed at the normal reproduction, generates a switching signal CHS to make a switch 20 open the tracking servo loop and superimposes a prescribed offset voltage V0 on the voltage VCMD. Thus, the capstan motor is driven at the speed being nearly a half of the normal speed. When an address is traced at a track TB actually to a track TA to be traced while the servo is disabled at a time T1, a recognized track number is coincident with a number traced actually at the time T2 to apply the track servo. Then the processing section 19 allows the switch 20 to close the servo loop thereby bringing the tape speed command to the normal speed command.

Abstract: PURPOSE: To give any coloring in a moment to a letter, a design etc. printed on a paper sheet for printing by utilizing the heat-coloring property of a heat-transfer type coloring sheet.  
     CONSTITUTION: In the method for giving optional coloring to a letter, a design and the like printed on a paper sheet for printing 1, especially to those printed on a aluminum-evaporated paper sheet by a electron-discharge destruction type printer, a heat-transfer type coloring sheet 2 is contacted on its colored surface fast with a printed paper sheet for printing 1, whereupon heat rays are radiated by a lamp 3. And the heat is absorbed by the printed part and the coloring material painted on the coloring sheet 2 is dissolved to transfer on and color the printed part of the paper sheet for printing 1.  
     EFFECT: The color thus transferred is dried instantaneously, and so even the immediate touch on the colored portion by hand gets no stain thereon. Moreover, the instantaneous and stable color printing on the aluminum-evaporated surface of paper which has not far been regarded as difficult turns thereby to be practicable.

Title: Electronic timepiece
Inventor: HORIKOSHI ICHIRO
IPC: G04C9/08
Filed: 1987-02-05
Abstract: PURPOSE:To stop a second hand at a next integral second display position and to perform an accurate time correction by initializing a frequency division part in synchronism with a one-second cycle signal when a user operates a pseudo continuous hand advance timepiece to stop the second hands. CONSTITUTION:When an external operation member 7 is operated, the potential at a point B becomes a source voltage and a latch 21 becomes ready to operate. The output of a master M of 64Hz is inputted from the frequency division part 2 consisting of toggle type FFs (TFF) 22 and 9-14 to the C terminal of the latch 21 and a 1Hz signal is inputted to the D terminal. Then when the 1Hz signal falls, the output of NOR 22 which inputs the 1Hz signal and the Q' of the latch 21 rises to a high level and the output of AND 17 also goes up to the high level, so that all TFFs of the frequency division part 2 and a latch 18 are reset. Consequently, a motor driving signal from a waveform formation part 3 is ceased and the second hand stops. The hands are therefore stopped in synchronism with the 1Hz signal at all times and the second hand stop position is an integral second display position on a dial, so that an accurate time correction is made.

Title: Semiconductor device
Inventor: TANAKA NOBUYUKI
IPC: H01L27/06
Filed: 1986-02-07
Abstract: PURPOSE:To prevent the titled semiconductor device from turning into a state of operation as a thyristor as well as to prevent the semiconductor device from destruction due to latch-up by a method wherein an impurity layer, having the impurity type same as a silicon substrate, is formed on the rear surface of the silicon substrate. CONSTITUTION:The difference between the titled semiconductor device and the device heretofore in use is that the former is formed with P-type impurity layer 10. After the prescribed semiconductor element has been formed on a wafer, the wafer is shaved and polished to the prescribed thickness, and boric ions are implanted on the rear side of the wafer. Then, boric ions are activated by performing a low-temperature annealing by the irradiation of microwaves, for example, and a P-type impurity layer 10 is formed. As a result, the P-type impurity layer 10 can be formed without damaging the semiconductor element already formed. Consequently, the P-type silicon substrate is prevented from turning into an N-type one, and the semiconductor device can also be prevented from breakdown due to the latch-up of a parasitic thyristor.

Title: Photosenser driving integrated circuit
Inventor: SAKAMOTO MIKIO
IPC: H04N5/335
Filed: 1986-02-06
Abstract: PURPOSE:To selectively pick up a signal charge out of an output line of only one photosensor driving integrated circuit for reducing total output capacity making reading with high sensitivity and at high speed feasible by a method wherein said circuit is composed of a scanning pulse generating circuit and switch elements to be provided with output change-over switch elements. CONSTITUTION:Signal charges are successively actuated from a photosensor driving integrated circuit 41 connected to output the signal charges in time series corresponding to the arrayal order of a-Si photoelectric conversion elements 11. For example, when a signal charge is read out of No.n photosenser driving integrated circuit 41, the output change-over switch element 13 only in the integrated circuit 41 is turned on while the other output change-over switch 13 in other integrated circuit is turned off. At this time, the drain diffused capacity and the interconnection capacity on photosensor driving integrated circuit are concentrated on the capacity of output change-over switch element 13 turned on. the drain diffused capacity of output change-over switch element 13 itself turned off is included of course but it is almost negligible due to far less number than that of switch element 5. Resultantly, the time constant is reduced making high speed reading feasible while improving the noise resistance.

Title: Method of burning fuel in burner with reduced amount of generated nox
Inventor: MORONAGA MASAHARU
IPC: F23C99/00
Filed: 1984-02-15
Abstract: PURPOSE:To make it possible to prevent the amount of generated NOx from increasing even when a load variation occurs by adjusting the opening degree of respective dampers by applying a bias to the load of the burner. CONSTITUTION:When a load increases, dampers 20 and 29 apply a bias to the opening degree from D1 to D5, and thereafter increases the opening degree up to D6, in accordance with the load variation by b2 which is paralled to b1. In this manner, a bias is applied to the minus side. On the other hand, an inlet damper 7 of a gas furnace applies a bias to D7 from D3 as shown in a diagram a2 so that the flow amount of the waste gas with respect to the dampers 20 and 29 can be sufficiently secured, whereby the increase in the amount of generated NOx is prevented even when the load of the burner such as a boiler varies. Then, when at a time T the load of the boiler becomes L2, and the rise of the load comes to a stop, the dampers 20 and 29 gradually throttle the opening degree in correspondence to the variation in the air supply amount. On the other hand, the damper 7 which applies a minus bias increases the speed of the increase in the damper opening within this period to obtain a predetermined opening degree D4.
