Title: Reading/writing circuit for magnetic disk recording/ reproducing device
Inventor: KOTANI TOKUMI
IPC: G11B5/09
Filed: 1986-07-08
Abstract: PURPOSE:To easily select a magnetic head as well as the damping resistance of the magnetic head by providing a load resistance of the magnetic head, a resistor connected in parallel to the load resistance, and a switch circuit which closes the resistor at the time of write mode and then opens it at the time of read mode respectively. CONSTITUTION:At the time of write mode a write drive reading circuit 6 performs a writing action and large voltages are produced at both ends of a write/read coil 2 of a magnetic head 1. Thus a diode 8 is activated. The damping resistance 5 is obtained by setting a load resistance 5 of the head 1 and a resistor 7 in parallel with each other. Thus the resistance value of the resistance 5 can be lowered. At the time of read mode, the diode 8 is not actuated since the voltages of both ends of the coil 2 are kept at the same level. Thus the damping resistance 5 of the head 1 includes the load resistance 5 only. Therefore the load resistance 5 of the head 1 is selected at the time of read mode to obtain a read waveform (a) and the resistor 7 is selected at the time of write mode to obtain a write current waveform (b) respectively.

Title: Building material having glazed foaming layer
Inventor: KITAHARA YOSHITSUGU
IPC: B32B18/00
Filed: 1991-07-01
Abstract: PURPOSE:To obtain glazed building material which has good touch in the case of touching it and moreover has the surface difficult to slip. CONSTITUTION:Building material having a glazed foaming layer with pores formed thereto is obtained by applying glaze incorporating a component for generating gas to the base of building material and thereafter burning it. The glazed surface of this building material is ground or polished. Thereby the building material is excellent in heat insulating properties and free from cold feeling in the case of toughing the same because the glazed layer is constituted of a porous layer. Further the roughness of the surface is large and its unevenness is small and slip is made difficult. When the surface of this glazed layer is ground and polished, the cross sections of pores are exposed on the surface and roughness of the surface is raised and the building material is made difficult to slip. In other words, in this case, even when the surface is wetted by water, a uniform water film is not formed and the building material is made difficult to slip.

Title: Gas flow rate control apparatus
Inventor: KOJIMA TADASHI
IPC: F23N1/00
Filed: 1980-11-14
Abstract: PURPOSE: To improve the flexibility of control and to secure the operation of the apparatus by a method wherein a part of a gas to be controlled is taken out to be supplied under pressure to a pressure chamber by means of an electromagnetic pressure supply device and valves are controlled by a responsive member which varies its position by detecting the pressure in the pressure chamber.  
     CONSTITUTION: When a piston 6 moves upward, the pressures in a cylinder chamber 7 and a supply chamber 10 decrease so that a check valve 8 is opened and the gas in a pipe 12 is sucked into the cylinder chamber 7 and the sucking chamber 19 through a pipe 13. On the other hand, when the piston 6 moves downward, the check valve 8 is kept closed and a check valve 9 is opened so that the gas in the cylinder chamber 7 flows into the pressure chamber 20 through a communication hole 19. As a consequence, the responsive member 23 is pushed downward and a valve body 24 connected to the responsive member 23 leaves away from a valve sheet 27 so that the gas within an inlet passage 26 flows into an outlet passage 27.
