Title: Device for detecting cassette in cassette tape recorder or the like
Inventor: SATOU MASAHIRO
IPC: G11B15/17
Filed: 1982-07-28
Abstract: PURPOSE:To detect the existence of a loaded cassette tape precisely, by using an output signal from a rotation detecting means of a tape winding driving part fitted to detect the final end of the tape. CONSTITUTION:A rotation detecting circuit 26 outputs a pulse signal A proportional to the turning speed of a reel motor 20. The output signal A is inputted to an integrating circuit 32 and an electric signal C to be changed in proportion to the turning speed of the reel motor 20 is outputted. The output voltage C is inputted to a comparator 34 and compared with reference voltage B outputted from a reference voltage generating circuit 36 and the compared result D is outputted. When the cassette tape is not loaded, the reel motor 20 is reduced at its load and turned at a speed considerably higher than that of the loaded status of the tape. In accordance with the difference of the period of the output signal A, the output voltage C is high at the load of the tape and low at the unloaded time. The reference voltage B is set up to the intermediate value of the difference of the voltage C which is generated by the existence of the cassette. When the cassette tape is not loaded, the output D is turned to the ''H'' level and the unloaded status is detected.

IPC: B41J29/00
Filed: 1993-06-02
Abstract: PURPOSE:To stably and exactly operate a heater controller even for the change of the thermal condition of an object to be heated without changing the cost of the controller. CONSTITUTION:The region of optimal temp. is set narrower than an allowable range around the target temp., the low temp. duty of an electric power supplied to a heater 6 when the surface temp. of an object to be heated 5 detected by a temp. sensor 7 is lower than the region of optimal temp. and the initial value of a high temp. duty when it is higher are set e.g. as 100% and 0%. The CPU 2 of a heater controller 1 detects the times for passing through the region of optimal temp. at the time of temp. rising and temp. drop, respectively, and by correcting the last low temp. duty and high temp. duty according to these times, the next low temp. duty and high temp. duty are determined. A duty controller 4 controls the power duty inputted from a power source 3 in accordance with a control duty signal inputted from the CPU 2 and supplys the power to the heater 6. The low temp. and high temp. duties are converged to the optimal duties, respectively.

Abstract: PURPOSE:To obtain the titled device having ideal guantum well optical waveguides with no fluctuation of interface caused by mixed crystals, by a method wherein a guantum well structure is made of only binary compounds into a structure without containing mixed crystals. CONSTITUTION:This semiconductor laser of guantum well structure has the successive growths of e.g. a superlattice clad layer 23 of the alternate laminations of N type GaAs and N type AlAs, a superlattice optical guide layer 24 of the alternate laminations of non-doped GaAs and non-doped AlAs, an active layer 25 of non-doped GaAs guantum well, a superlattice optical guide layer 26 of the alternate laminations of non-doped GaAs and non-doped AlAs, a superlattice clad layer 27 of the alternate laminations of P type GaAs and P type AlAs, and a P type GaAs cap layer further thereon. Such a structure enables light to be effectively guided with the active layer 25 as the center. Since the optical guide layers 24 and 26 that importantly influence the formation of quantizing level of the active layer 25 do not contain mixed crystals, an excellent guantum effect can be obtained with no fluctuation caused by mixed crystals.

Title: Buffer type gas circuit breaker
Inventor: MIZOGUCHI HITOSHI
IPC: H01H33/91
Filed: 1988-06-01
Abstract: PURPOSE:To restrain a surge voltage upon closure of contact by composing a resistor contact of two point contacts capable of arbitrarily setting opening speed and a gap between the contacts interlocked with the movements of movable contact and the opposed contact. CONSTITUTION:When an opening force is exerted through an insulation rod 9, a movable contact 1 and a buffer cylinder 4 are moved rightwards while an opposed contact 2 is driven reversely. Contact elements 11b, 13b of a resistance contact B are driven while interlocked therewith. At this time, the elements 11b, 13b work in the contact B, and contact elements 11b, 13b pushed by spring tend to move with the elements 11b, 13b. Since gas in spaces C1, C2 of cylinder is compressed at that time, the elements 11d, 13d move with a slight delay after the movement of the elements 11b, 13b. The contact B is thus opened earlier than a breaking contact A. When the contact A is opened, gap 11, 13 are ensured. It is thus possible to generate arcs upon breaking at the contact A without the generation at the part B.
