Title: Tape sound recorder
Inventor: TSUCHIYA MITSUNORI
IPC: G11B27/22
Filed: 1979-12-26
Abstract: PURPOSE: To ensure an automatic head leading action with the detection output, by writing for a fixed period the frequency signal under the audible frequency and used for head leading and detecting the written frequency signals.  
     CONSTITUTION: The head leading detection circuit 6 consists of a low pass filter and voltage comparator, and the automatic head leading action is given in the quick winding and reproduction modes. Thus the redorded head leading signal of 10W 20Hz is reproduced as the signal of 200W400Hz. In this connection, the cut-off frequency is set to the low pass filter so as to pass only the reproduced head leading signal. In the case of input of the jumping address, the counter circuit 7 counts the input pulses by the up-counting action and counts the pulses sent from the circuit 6 by the down-counting action. Thus the stop signal of the feed action is produced by the zero output of the count number, performing an automatic head leading action.

Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a portable heater and warmer having its own heat source by bonding a heat insulating sheet formed of a heat insulating fiber to a heating sheet formed of a heat conductive fiber, and arranging a heating part for heating a heat medium and a pump device for circulating the heat medium in a part of the heating sheet. SOLUTION: When a heating part 4 such as catalyst burning device using benzine as fuel is heated, a heat medium 5 is circulated in a circulating passage 3 by pumping action of a pump device 6 such as heat driving pump to which evaporation and condensation of the heat medium 5 is applied. By this circulation, heat possessed by the heat medium 5 is transmitted from a wall surface of the circulating passage 3 to the whole surface of a heating sheet 1 formed of a heat conductive fiber. Since a heat insulating sheet 2 is stuck to the reverse side of the heating sheet 1, the heat transmitted to the heating sheet 1 is prevented from being diffused, and the heat generated from the heating part 4 can be efficiently utilized for heating and warming. As the heat medium 5, water or a mixture in which 35% alcohol is mixed to water is used.
