Abstract: PURPOSE:To obtain a magnetic head which has good wear resistance and is strong to thermal change by constituting a shielding material of ceramics, ferrite, and ceramics in this order into a sandwich state and uniting the laminate into one body by glass welding. CONSTITUTION:Ferrite cores 10, 10' adhered by glass 11 are provided with shielding grooves 14, 15, 16. A nonmagnetic sheet 17, ferrite sheet 18 and nonmagnetic sheet 17' are formed in such a manner that the total laminated thickness is smaller by about 0.02-0.2mm than the width (m) of the working grooves. The nonmagnetic sheets 17, 17' for shielding to contact the traveling surface of a magnetic tape and the ferrite sheet 18 are formed wider by at least 1mm or above than the ferrite cores 10, 10' forming the track. The respective parts are fixed by jigs and bonding glass is placed thereon, then the parts are subjected to a heat treatment in an electric furnace in which a reduced atmosphere is maintained in the case of a core 1 consisting of Mn-Zn ferrite. The bonding glass is thereby melted and the laminate is fixed.

Title: Incoming signal detection system
Inventor: KINOSHITA TOSHIMASA
IPC: H04Q3/42
Filed: 1989-10-30
Abstract: PURPOSE:To simplify the circuit constitution by setting/resetting a flip-flop circuit corresponding to the polarity of a ringing signal. CONSTITUTION:A photocoupler 332 detects a negative polarity of a sinusoidal wave ringing signal inputted thereto and a photocoupler 333 detects the positive polarity and a signal shown in waveform 41 is generated cross diodes of the photocouplers 332, 333. The photocoupler 332 is conductive for the period when the waveform 41 is negative and generates a rectangular wave shown in a waveform 43 and outputs to a set terminal of a flip-flop circuit. The photocoupler circuit 333 is conductive while the waveform 41 is positive and a rectangular wave shown in a waveform 42 is generated via an OR circuit 334 and outputted to a reset terminal of the flip-flop. Thus, the ringing in a rectangular wave and a sinusoidal wave is received for a period in response to a ringing signal to simplify the circuit constitution.

Title: Air-conditioner
Inventor: TANAKA HIROYUKI
IPC: F25B39/04
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a return of a refrigerant to a compressor when a compressor is in an intermittent operation state at a low frequency. SOLUTION: An air-conditioning device comprises a refrigerating cycle constituted in such a way that a compressor, an outdoor heat-exchanger, an expansion mechanism, and an indoor heat-exchanger 5 are coupled, in the order, to each other through a refrigerant piping; and an inverter device. The indoor heat- exchanger 5 functioning as an evaporator during cooling operation is provided with heat-transfer pipes 21 and 22 being two-pass constitution through which a refrigerant flows. The heat transfer pipes 21 and 22 of each pass are formed such that the inside diameter (a crosssectional area) of a heat transfer pipe 21 of a first pass is increased to a value higher than the inner diameter (a sectional area) of the heat transfer pipe 11 of a second pass.  Since, when the compressor is in an intermittent operation state at a low frequency, the pressure of a refrigerant is not increased, a liquid refrigerant gathers at the heat transfer pipe 21 of the first pass having a high sectional area due to reduction of the velocity of flow of the refrigerant.

Title: Output reference level holding method in picture reader
Inventor: MOCHIDA HIROHIKO
IPC: H04N1/407
Filed: 1988-11-11
Abstract: PURPOSE:To accurately keep an optical shield picture element signal level by prolonging the period of a transmission clock and a reset clock and lowering the frequency of an optical shield picture element signal and applying sample- hold. CONSTITUTION:The generation of a reference clock from a reference clock generating circuit 24 is stopped tentatively in the timing when an optical shield picture element signal Dn is outputted from a line sensor 21. Then the period of generation of transfer clocks phi1A, phi2A, phi2B from a transfer clock generating circuit 24 and a reset clock RS from a reset clock generating circuit 23 is prolonged tentatively by a reference clock stop period only. Since the optical shield picture element signal has a low frequency when a sample-hold circuit 26 samples and holds the level of the optical shielding picture element signal, even if the band a 1st operational amplifier 26a is narrow, the optical shielding picture element signal level is held accurately in a hold capacitor 26d via the operational amplifier 26a.

Filed: 1986-11-28
Abstract: PURPOSE:To satisfactorily recognize the state of clamping of soil by projecting the electromagnetic wave of a prescribed frequency into a bulk substance clamping the soil, receiving a reflected wave, and analyzing an electric characteristic. CONSTITUTION:The electromagnetic wave W of a frequency which is influenced most intensively by the clamping of the soil 2 is transmitted from a transmitter 5, and the electromagnetic wave W reflected from the boundary of a substrate 1 and the soil 2 is received by a receiving antenna 4 and sent to a receiver 6.

These electric characteristics are varied by the clamping degree of the soil 2, therefore, by reading such electric characteristics, the clamping degree of the soil 2 can be known. In such a way, the measured and analyzed electric characteristics can be displayed by a graph, etc., by an indicator 8.

Title: Noise reducing device
Inventor: FUJITA SAKAE
IPC: H04N5/208
Filed: 1991-10-04
Abstract: PURPOSE:To reduce the prominence of a noise on a screen at the time of emphasizing a sharpness, at the time of a weak electric field. CONSTITUTION:A luminance signal is clamped by a clamp circuit 2 so that the top of the sink chip can be turned to a prescribed voltage V0. The sink chip of the luminance signal clamped by the clamp circuit 2, which is less than a prescribed level, is detected by a slice circuit 3. The detected sink chip is amplified by a high-pass filter and an amplifier circuit 4, and the envelope detection is operated by a peak detection and hold circuit 5. Thus, noise components superimposed on the sink chip are detected. When the detected noise components are more than the prescribed level, a slice circuit 6 outputs the components to a subtracting circuit 7. The components supplied from the slice circuit 6 are subtracted from a manually set sharpness control voltage by a subtracting circuit 7, and supplied to a sharpness circuit 1.
