Title: Flat heater
Inventor: KAKUNO KATSUAKI
IPC: F24D13/02
Filed: 1992-06-15
Abstract: PURPOSE:To allow local temperature control so as to extend application fields by making such constitution as providing switches to respective heater elements and performing on/off control according to outer pressure acting on the appropriate heater elements. CONSTITUTION:Power feeding to heater elements 12 is performed repeatedly via wires a1-1n, b1-1n respectively individually at predetermined intervals by controlling relays RLC1-RLCn, RLL1-RLLn. If there is no external pressure on the elements 12, both contacts 24, 26 of a switch device 22 are made to be in their opened state by an elastic spring element 28 and current flows to the elements 12 so that an electric heater element plate 18 generates heat. Application of outer pressure on the elements 12 makes the contacts 24, 26 closed so that electric current shunts the element plate 18 and detours around the device 22 so as not to generate heat. This constitution allows local heating control in a heating area 10 according to arrangement of materials.

IPC: H01P3/02
Filed: 1989-06-16
Abstract: PURPOSE:To obtain a semiconductor IC forming an extremely miniaturized monolithic microwave IC by forming dielectric having a dielectric constant larger than that of a semiconductor substance on the substrate and forming a coplanar line on the dielectric. CONSTITUTION:The dielectric 2 having a dielectric constant larger than that of the semiconductor substrate 1 is formed on the substrate 1 and a microwave circuit consisting of the coplanar line (a signal line 2 and a ground line 4) is formed on the dielectric 2. Since the dielectric having the large dielectric constant is used, electric wavelength on the dielectric 2 is shortened and the length of the microwave circuit constituted of the coplanar line is shortened, the chip size can be sharply reduced. When the dielectric with about 70 to 100 dielectric constant e.g. is used, the area of the chip is contracted to <=1/10 the ordinary area.

Title: Automatic returning and locking mechanism for positioning device
Inventor: HANABUSA SHUICHI
IPC: G11B21/22
Filed: 1986-07-01
Abstract: PURPOSE:To obtain a great locking force and to eliminate touch points by setting the dimensions of a magnet and the projecting part of a cam member and their relative positions to the specific relation. CONSTITUTION:The cam member 10 has the projection part 10a disposed so that it can be located in a position confronted with the magnetic pole surface of the magnet 11 if a magnetic head 3 lies in an area (CSS zone) where the head 3 is brought into contact with a magnetic disk, and a cam surface formed in such a way that a gap between the projecting part 10a and the magnet 11, which extends from the projecting part 10a, can be wider as the magnetic head moves towards an area (R/W zone) where information is written and read. Then the width of the magnet 11 is the same as that of the projecting part 10a, and the magnet 11 stops in a position relatively shifting by 1/2t towards the CSS zone and in a position where the magnetic head returns to the CSS zone. Thus the locking force between them is maximized.
