IPC: H01L29/78
Filed: 1978-08-18
Abstract: PURPOSE: To prevent the occurrence of pin holes in a phosphor glass layer by performing the connection of metallic wiring and a semiconductor substrate in the openings formed in the phosphor glass layer.  
     CONSTITUTION: On a p-type semiconductor substrate 11, insulating films 12 and 13 consisting of silicon oxide films are formed selectively, and after openings 14 are formed in the silicon film 12, a polycrystalline silicon film 15 is overlapped over the surface and an oxidation resistant insulating film 16 is formed. Next, forming the first pattern of 17, 18, 19, etc., on the films 15 and 16 and using it as a mask, the film 13 is etched and the semiconductor substrate 11 is exposed. Next, after forming a phosphor glass layer 20 all over the surface, openings 21 are formed, the film 16 is exposed selectively, the surface of the glass layer 20 is smoothed by a heat treatment at a high temperature, and at the same time, impurities are duffused from the film 15 and the glass layer 20 to the substrate 11, and thus the n-type duffusion layer 22 of sources, drains, etc., is formed. Next, the selectively exposed film 16 is removed to expose the film 15, and a metallic wiring layer 23 is formed.

Title: Thermal head
Inventor: TANIGUCHI YOSHIAKI
IPC: B41J2/335
Filed: 1988-04-26
Abstract: PURPOSE:To accomplish a uniform heat distribution with a small heating value and to obtain a high-quality image, by a method wherein heating resistors are formed on a heat accumulation layer provided on a substrate, a first protective layer of high heat conductivity is formed on nearly the upper part thereof, and a second protective layer lower than the first protective layer in heat conductivity is formed on the both sides thereof. CONSTITUTION:An under-glaze layer is screen-printed on a substrate 1 and, succeedingly, Au is screen-printed over the full surface of the under-glaze layer 2 and baked. Electrodes 3a, 3b are formed by an etching treatment. For example, a RuO2 paste is screen-printed between the electrodes 3a, 3b and baked to form a resistor 4, and thereon a glass layer 7 is formed by screen-printing etc. Subsequently, on the both sides of the glass layer 7, glass layers 6a, 6b having a heat conductivity lower than that of the glass layer 7 is formed by screen-printing etc. and baked. In this manner, the heat generated by the resistor 4 is transmitted to the glass layer 7 serving as an upper protective layer, but is prevented from laterally flowing because of the provision of the glass layers 6a, 6b having a conductivity lower than that of the glass layer 7. Thus, the heat mainly flows only in an upper direction.

Title: Bed device and driving method of floor plate
Inventor: OSHITA SHOJI
IPC: A61H1/00
Filed: 1992-04-21
Abstract: PURPOSE:To selectively do healthy exercises by use of a bed device by controlling the swing phases of divided parts oscillated by the driving side and driven side respectively. CONSTITUTION:On putting on an operation switch 37b, a light receiver 35 detects first the light from a projector 34 through a pin hole 32 of a slit plate 33 and the currents to an electromagnetic clutch 31 are cut off to rotate only the driving part 23a. And hence, only divided half 11 of a pair at one side in the width of the bed frame oscillates. When the slit plate 33 is rotated 90 degree in this condition and light beams are received through the next pin hole 32, electric currents are conducted to the electromagnetic clutch 31 and the drive side 23a is connected to the driven side 23b. Thereby, the divided half 11 of the pair at the other side in the width of the bed frame starts to oscillate again in the condition deviated by 90 degree from the divided half 11 of the couple at one side. If putting on again, the slit plate is rotated 180 degree, or the vertical motion of the right and left divided halves 11 can be reversed. Accordingly, users can select the kind and strength of the motion.

Title: Injection method of inject printer
Inventor: AKAO AKIO
IPC: B41J2/13
Filed: 1978-08-18
Abstract: PURPOSE:According to the size of electrical signal, transmitting timing to an ink head is delayed. By doing so, ink drip on the printing paper is equally stuck and then printing discrepancy due to the difference of ink injection speed is to be prevented. CONSTITUTION:For example, a video signal Vp1 is transmitted to a delay circuit 12 beforehand and it is compared with minimum signal Vp4. At this time, a syncronizing signal Tp1 being transmitted is delayed by a delaying time d1 through the comparison with the signal Vp1 and then it is output to a switching circuit 13 as a delaying signal Dp1. On the other hand, the signal Vp1 is amplified at an amplification circuit 10 and it is transmitted to an ink head 11 as pulse shaled head transmitting signal Hp1. After that, a maximum ink drip I1 is injected to the printing paper with the speed V1 from the orifice. Then, as the same, an ink drip I2 is injected by a video signal Vp2. At this time, V1 is greater than V2 and ink drip can be stuck in the designated position.

Abstract: PURPOSE:To prevent the breakage of a film by a method wherein a silicon hydroxide film containing impurities and a solvent is applied on a substrate through a mask with a predetermined pattern and the opening section of the mask is formed in taper shape when the impurities are diffused in the substrate by applying heat treatment. CONSTITUTION:An SiO2 film 2 serving as a diffusion mask is formed on a P type Si semiconductor substrate 1 and etched halfway by using a resist film 13 as a mask. Then, with the film 13 slightly ashed by using plasma-asher, the opening section of the film 13 is expanded. At that time, etching is again performed. After forming an opening pattern with a taper shaped section on the film 2, the substance dissolved Si(OH)4 and As2O3 including an N type impurity in acetone is applied to the surface to form a layer 3. Next, heat treatment is applied to make an N type region 5 by diffusing N type impurity As into the substrate 1. Therefore, a tapered edge 7 exists. Thus, the film 3 will not be broken even if the film 3 contracts at the time of heat treatment.

Filed: 1990-04-18
Abstract: PURPOSE:To raise a write voltage for improving tolerance to soft errors at the time of wiring and reading by making the impurity concentration of a semiconductor substrate at the lower par of a channel region of an access transistor lower than that of a driver transistor. CONSTITUTION:Impurity concentration of a semiconductor substrate 2 at the lower part of channel regions of access transistors Q3 and Q4 is made lower than that of driver transistors Q1 and Q2. The impurity concentration of the semiconductor substrate 2 at the lower part of the channel regions of the driver transistors Q1 and Q2 is the one to correspond to the gate length of the driver transistors Q1 and Q2. Independently of this, the impurity of the semiconductor substrate 2 at the lower part of the channel regions of the access transistors Q3 and Q4 can be the one to correspond to the gate length of the access transistors Q3 and Q4. Consequently, the impurity concentration of the semiconductor substrate 2 at the lower part of the channel regions of the access transistors Q3 and Q4 can be prevented from rising higher than necessary level. As a result, this semiconductor memory comes to be unsusceptible to a substrate bias effect.
