Filed: 1981-10-09
Abstract: PURPOSE:To unnecessitate the surplusage for the mask alignment of an electrode aperture, by connecting a wiring layer to an impurity layer or the other wiring on an Si substrate via a low resistant Si layer. CONSTITUTION:The first Al wiring layer 13 is provided on the SiO2 12 on the substrate 11, the high resistant Si layer 14 is superposed by a plasma CVD method, a resist mask is applied, P ions are implanted, and accordingly the impurity layer 15 is formed at the part of connection of the layer 14 and 13. Then it is annealed in N2 resulting in the activation. Next, the second Al wiring is superposed. By this method, since the minimum value of wiring intervals can be determined only by substantial intervals: dimension d=e=0.3mum, the wiring interval f can be set to approx. 1mum the limit of the exposure device. Thereby, the wiring interval becomes narrower than convention by approx. 30%.

Title: Transformer
Inventor: IKEDA MASAMI
IPC: H01F27/10
Filed: 1981-10-09
Abstract: PURPOSE:To provide a transformer with large capacity and dielectric strength, and freed from cavitation and static electricity discharge, by a method wherein both end portions of a cooling duct are put out of both ends of a leaf coil insulating sheet and expanded in the circumferential direction. CONSTITUTION:A cooling duct 7 has expanded tubiform portion 17 at the both ends, so refrigerant carriers gather from all over the liquid path 19 to the cubiform portion 17 of which sectional area is large. The refrigerant carriers, then, flow out to a insulating pipe 12 via a joint 21. Due to this large sectional area of the cubiform portion 17, the flowing speed of the refrigerant carriers around the joint 21 can be lowered, and cavitation and static electricity discharge used to be caused by increment of the refrigerant carriers flowing speed can be prevented, as well as the cooling duct is protected from erosion.

Title: Boiling cooling device
Inventor: OKADA TEIGO
IPC: H01L23/44
Filed: 1979-12-14
Abstract: PURPOSE:To increase the cooling capacity of a boiling cooling device by reducing the gap between the boiling cooling piece of a heat dissipating stack and a container and thereby accelerating the coolant flowing velocity. CONSTITUTION:The cooling piece 3 making contact with a semiconductor element 2 is boiled due to the heat from the element 2 to thus allow the element 2 to be cooled by evaporating latent heat of the piece 3. Vapor thus produced is fed through a tube 8, is cooled by a condenser, and the coolant thus liquified is again circulated and cooled through the tube 9 within an inside container 10. Since the flowing velocity of the vapor and coolant is accelerated when the vapor and coolant are fed through the gap 13 between the container 10 and the cooling piece 3 and boiling heat is transmitted thereto as well as the heat transmission due to the forcible convection thereof is applied thereto, the cooling capacity is increased. Semiconductor stack 2A can be contained in the container 10 to thereby increase the cooling performance of the boiling cooling piece 3 and to reduce the size thereof, and the outer diameter and the inside of the stack 2A as well as the size of the outside container can be reduced respectively.

Filed: 1995-06-28
Abstract: PURPOSE: To output each page of image data to a desired page depending on designation information by deciding to which page each page of the image data is composited by an output decision means. CONSTITUTION: An output page decision means 16 places priority on designation information received by a host interface (I/F) 11a from designation information received by a designation information input means 15. When a host device 20 sends image data comprising plural pages and designation information corresponding to each page of the image data, an output device 10 uses the host I/F 11a to store the data tentatively to a storage means such as a hard disk. When reduced information is received by a designation information input means 15, the information is stored in a register in an output page decision means 16. A display page designation means 18 stores display information to a storage means by the user.  Then an image processing means 12 extracts the data from the 1st page sequentially, the data are processed by an image expansion section 12a and recognized by a recognition means 14 and the result is outputted.

Title: Method for cleaning liquid ejection head in liquid ejection recorder
Inventor: KIDA AKIRA
IPC: B41J2/165
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning method for a liquid ejection head in a liquid ejection recorder capable of completely cleaning an ejection face by the number of times of wiping which is less than heretofore. SOLUTION: When a recording head 1 moves in a direction toward a wiper 16 and a base plate 86 of the recording head 1 reaches a position abutting the wiper 16, the recording head 1 goes into a stand-by condition at the position. When the wiper 16 abuts the base plate 86 which is in a heat-radiating condition, the vaporization of a volatile component in ink remaining on the wiper 16 is accelerated so that the viscosity of the remaining ink is increased. The recording head 1 further moves toward the wiper 16. At that time, the ink of which viscosity is increased is sufficiently scraped by an edge section 87 of the recording head 1. As a result, the wiping of an ejection face 81 after the scraping is executed in a condition that the ink is not stuck to the wiper 16.
