Title: Manufacture of static induction type semiconductor device
Inventor: YAMAMOTO HARUHIKO
IPC: H01L29/80
Filed: 1987-02-21
Abstract: PURPOSE:To eliminate the variability of withstanding voltage between a gate and a cathode by a method wherein, after a plurality of opposite conductivity type regions are formed on one surface of a semiconductor substrate by diffusion, the regions are etched except the bottom parts which are used as gate regions and cathode regions are provided on the parts of the substrate protruding between the gate regions. CONSTITUTION:A plurality of P<+> type regions 6 are formed in an N<-> type Si substrate 5 with intervals by diffusion. With insulating films 7 formed on the surfaces of the substrate 5 between the regions 6, the regions 6 are removed by etching except the bottom parts which are used as gate regions 10. Then apertures 9 are formed in the films 7 on the protruding surfaces of the substrate 5 and the films 7 are covered with doped polycrystalline silicon films 12. The impurity in the silicon films 12 is diffused by a heat treatment to form N<+> type regions 11 which are used as cathode regions on the protruding surfaces of the substrate 5. After that, the previously used silicon films 12 are again utilized as cathode electrodes 12. With this constitution, the distance between the gate and the cathode along the vertical direction can be defined so that the yield can be improved.

Title: Image forming method
Inventor: YOSHINO YOSHIE
IPC: G03G15/06
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device capable of stabilizing the intensity of developing electric field further by using a means for applying a voltage to the surface of a developer carrying roller as a voltage applying means. SOLUTION: A recovery blade 16 abutting on a developing roller 12 is made of a material adjusted to be low-resistance one by dispersing conductive particles in metallic material such as stainless, and a power source 13 is connected to the blade 16. Thus, a developing bias is applied to the surface of the roller 12 through the blade 16. At such a time, by setting the surface electric resistance value of the roller 12 within the range of 0 to 108 [Ω/square], the effective developing electric field is formed without applying the developing bias showing an excessive value. By using such a developing bias applying means, the intensity of the developing electric field is stabilized. Therefore, a situation that the intensity of the developing electric field gets unstable because an insulating layer is formed on the surface of the conductive center shaft of the roller 12 is eliminated.

In new metallic rood plates 30 on the upper-stage side, the lower sides are engaged with the new metallic roof plates 34 on the eave-edge side through new clips 33, and the upper sides are fixed onto the backup materials 31. Backup materials, on which Chinese-ink lines are marked at the same pitches as those of the existing rafters, are preferable as the backup materials 31. Accordingly, since new roof substrate surfaces are shaped by the backup materials 31, the new metallic roof plates 30 are laid by the same procedure as works to a new house.

IPC: G06F13/00
Filed: 1993-02-26
Abstract: PURPOSE:To continuously supply electric power to a device main body by storing power-ON time data on an external device, setting the power-ON time data which is clocked most early, and supplying the electric power to the device main body and making the stop of electric power supply by a signal from the external device invalid when the time is clocked. CONSTITUTION:This terminal device is provided with time buffers 42 and 43 which store power-ON time data sent from primary stations 36 and 37 and a time storage part 51 in which the time that current time clocked by a timer 48 reaches most early among the power-ON time data in the time buffers 42 and 43 is sets; when the set time is clocked, a power source control part 49 supplies the electric power to the device main body 31. At the same time, a power-OFF instruction from a primary station other than the station which sends the time is made invalid and when the power-OFF instruction is received from the primary station, the power-OFF instruction is made invalid even after the set power-OFF time is behind the current time on condition that their time difference is less than a certain time. Thus, the versatility is improved and the power source is prevented from being turned ON and OFF frequently.

IPC: C22F1/08
Filed: 1981-03-18
Abstract: PURPOSE: To obtain a copper alloy for electricity conduction whose softening temperature is significantly lowered, by hot rolling a copper alloy rod containing Zr and Cr into a rough rolled wire, and cooling it under conditions wherein it is kept for a prescribed period at a temperature in the prescribed range.  
     CONSTITUTION: A copper alloy rod containing Zr (for example 0.2%) and Cr (for example 0.2%) is hot rolled into a rough rolled wire. Then the rough rolled wire is cooled, for examle, in a N 2 -containing gas atmosphere. In this cooling process, when the rough rolled wire is retained at 500W650°C for about 1hr, the softening temperature of the copper alloy for conducting electricity containing Zr and Cr can be significantly lowered. Consequently, as the annealing temperature of said copper alloy can be lowered, the production efficiency can be increased, and the energy can be saved.

IPC: F04D29/02
Filed: 1979-03-30
Abstract: PURPOSE: To facilitate removal of dirt from a ventilation fan by a method wherein a strippable resin paint comprising water as the solvent and containing no plasticizers (e.g., DOP, DBP) is applied to those surfaces of a ventilation fan which contact dirty air, and a stripping coat is formed there.  
     CONSTITUTION: A strippable resin paint comprising water as the solvent and containing no plasticizers (e.g., DOP, DBP) liable to erode synthetic resin is applied to those surfaces of the main body frame 1, orifice 2, shutter 3, motor 4 and vanes 5 of a ventilation fan which contact dirty air. The paint is dried and hardened to form a stripping coat. For example, a water-soluble strippable resin paint comprising polyvinyl alcohol and polyvinyl acetate as the base resin is diluted with water to attain an adequate viscosity, applied to the cleaned surface of a substrate A in a thickness of about 30μ, and dried at ordinary temperature for about 2 hours to form a stripping coat B. Dirt C adhered to the surface of the substrate A can be removed simply by stripping the coat B.

Abstract: PROBLEM TO BE SOLVED: To simplify the current control in three-phase driving by selecting only the angle range of one line space, wherein the maximum magnetic-field change is obtained, among the magnetic fields between the lines of respective windings, making a current flow through the line space to drive a motor. SOLUTION: A rotor position signal is inputted into an operating part 1A, which receives a current command ICMD. At the same time, this rotor position signal inputs a current ICMD', which is operated through the operating part 1A, into a switching part 20 through an operator 3 and a PWM circuit 6. By the position signal of a rotor from the switching part 20, one line space, wherein the maximum magnetization change is obtained, that is to say, any two of power amplifiers 9, 10 and 11 are selected. The signal, which has undergone PWM conversion in correspondence with the current ICMD', is supplied into that part. Furthermore, the signals are supplied to respective windings 13-15 through the respective power amplifiers 9, 10 and 11, and the rotor of a motor 12 is rotated and driven. Thus, the current control in three-phase driving can be simplified.

IPC: B01D9/02
Filed: 1987-02-25
Abstract: PURPOSE:To produce a high-quality crystal without any flaw in spite of its rapid growth by controlling the velocity of an upward current on the outside of a draft tube. CONSTITUTION:When an impeller 18 is rotated in the crystallizer 1 provided with the draft tube 4 and a baffle plate 7, an downward current is formed on the inside of the draft tube 4, an upward current is generated on the outside, and a circulating current is formed between the inside and outside of the draft tube 4. The flow velocity of the upward current on the outside of the draft tube 4 is sufficiently decreased by adjusting the r.p.m. of the impeller 18 and the pitch angle of the impeller, hence the crystal of the size visible from the outside and floated up by the upward current to some extent does not overflow the upper end of the draft tube 4, and the crystal is not circulated along with the upward current. As a result, a high-quality crystal without any flaw can be produced in spite of its rapid growth.
