Filed: 1995-05-15
Abstract: PURPOSE: To decrease the number of parts and to drastically decrease man-hours by providing a rotary magnetic head device with a flexible wiring board for electrically connecting the lead wires of the coil of a rotating side rotary transformer core and a magnetic head. CONSTITUTION: A coil holder 11 as a holding means is fixed to the rear surface of a rotor core 6a. This coil holder 11 hooks and holds the lead wires 12 extending from the coil of the rotor core 6a. The lead wires 12 are positioned by the coil holder 1 with a recessed part which is the reference for the phase of the rotor core 6a as a reference. The lead wires 12 are held under the guide of the coil holder 11 and are drawn out in a specified direction (for example, nearly the radial direction of the rotor core 6a). The treatment of the lead wires 12 extending from the coil of the rotor core 6a involves merely hooking and holding of the lead wires 12 to the coil holder 11 without requiring the work to solder the lead wires to a terminal board, etc., in such a manner, thereby, the production cost of the rotor core is reduced.

Title: Heat transferring device
Inventor: OOKUBO MASARU
IPC: F24D17/00
Filed: 1984-07-05
Abstract: PURPOSE:To provide an immediate feeding-out of hot water a little volume of cold water even in case of initial application of hot water by a method wherein in case of performing a heat exchanging operation between the steam and the cold water, the heat exchanging surfasce is mounted in a flowing water. CONSTITUTION:Cold water coming from a tap water pipe 14 becomes steam heated by a heater source 1 at an operator's heat exchanger 9 and further becomes hot water heated by steam reached to a radiater 9-a. With the thermal solenoid shut-off valve 8, steam from the heater source 1 opens or closes the passage reached to the operator's heat exchanger 9 or a heat exchanger for bath by a packing B-e. The driving source is operated such that an application of electric current to a solenoid coil 8-a causes a movable iron piece 8-d to be suctioned in a leftward direction and the packing 8-e causes the steam to be flowed. With such an arrangement as above, since the heat exchanger is placed in the flowing water, resulting in making a small-sized unit and thus it is possible to change over the tap water and the hot water with one faucet.

Title: Information recording material
Inventor: TSUNEKAWA TAKEYUKI
IPC: B41M5/26
Filed: 1990-05-30
Abstract: PURPOSE:To enable repeating recording and erasing with low energy and in a short time by constituting an information recording material in such manner that the information recording material is mainly composed of a high-molecular organic substance and the glass-transition temperature of the recording material has a specific temperature region and the storage elastic modulus and loss tangent of the material are within a specific range. CONSTITUTION:Stress is applied to a recording material 1 having a smooth surface by a metal mold 3 having an irregular shape at a temperature T1 exceeding a glass-transition temperature (Tg) to give distortion. Then, the recording material is cooled to a temperature T0 lower than Tg so that the distortion is fixed. When temperature is elevated again to T2 by a heating mean 4 under conditions where no pressure is applied or such low pressure as giving no substantial deformation is applied, the surface of the recording material recovers from the distortion and returns to the original smooth surface. When this principle is applied, the distortion is given in the temperature region higher than the glass-transition temperature (Tg) and is fixed in that lower than Tg. Therefore, Tg is required to be within the range of 50-140 deg.C. Also the recording material is required to have an appropriate elastic modulus E-, which is within the range from 6X10<6> dynes/cm<2> to 1X10<8> dynes/cm<2> at a temperature 30 deg.C higher than Tg. Further, the recording material is restricted by the value of a loss tangent tandelta in the temperature region from the temperature region from the temperature, where the distortion is given, to Tg and the value of tandelta in the temperature region from Tg to the temperature 30 deg.C higher than Tg is required to be not less than 0.15.

Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a short circuit due to moisture, by heating a region exposed to the risk of moisture, evaporating the formed moisture deposit, or preventing the generation of the moisture deposit by means of heating. SOLUTION: An acceleration pick-up 7, a current sensor 9, a compactor 15, a microprocessor (CPU) 16, etc., are arranged on a printed board 1. The current sensor 9 acts as a moisture sensor. The compactor 15 outputs a signal to the CPU when moisture condenses on the current sensor 9 due to dew condensation and a potential at a terminal 12 falls to a predetermined value. The CPU 16 sends a signal to a transistor 22 to operate a hating element 20 for heating the vicinity of the acceleration pick-up 7 and the current sensor 9. When the moisture condenses on the current sensor 9 is evaporated, the CUP 16 stops the heating operation of the heating element 20 via the transistor 22.

Title: Electric discharge electrode feeding control device
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1979-10-31
Abstract: PURPOSE:To eliminate exessive feeding occurring at the time of high-speed feeding and feeding irregularity occurring at the time of low-speed feeding, by changing time constant of feeding control system in accordance with feeding speed. CONSTITUTION:When processing energy is given from a power source PW to an electrode D and a work WK, and processing voltage VG is impressed, electric discharge is started. At this time, a voltage is obtained in proportion to the processing voltage VG from a contact between resistances R1 and R2 connected between the electrode D and the work WK, and this voltage is impressed to an low-pass filter FIL. This voltage is smoothened by this FIL, impressed to a control circuit CONT and compared with a reference voltage, and as a result, such a control as to stop feeding of the electrode D and the work WK temporarily, etc. is conducted. In case when high-speed constant speed feeding process is taking place at a high feeding pulse frequency, time constant of FIL becomes small enabling the feeding control system to respond at a high speed. And in the case of conducting a low-speed constant-speed feeding process at a low feeding pulse frequency, the tendency is reverse.
