Title: Magnetic recording and reproducing head
IPC: G11B5/127
Filed: 1992-03-18
Abstract: PURPOSE:To decrease the load of a driving mechanism in a magnetic recording and reproducing device by decreasing tape tension while maintaining an excellent head touch between a magnetic tap and a magnetic gap which is provided on a magnetic recording and reproducing head. CONSTITUTION:The head is provided with a magnetic gap 14 for recording and reproducing information to the magnetic tape 2 and the magnetic tape and is provided with the magnetic gap 14 nearly in the center and a sliding surface 13 to a magnetic recording medium which slides in contact with the magnetic tape and is formed with a specified curvature so as to come into contact over the specified length of the magnetic tape 2 and whose length in the traveling direction of the magnetic tape is 0.2-1.0mm. Thus while excellent head-touch between the magnetic tape 2 and the magnetic gap 14 is maintained, the magnetic tape tension is decreased.

Title: Vibration absorbing device for brake
Inventor: MATSUMURA YOSHIHIRO
IPC: F16D65/00
Filed: 1986-03-18
Abstract: PURPOSE:To effectively absorb vibration by reducing the area of a passage between an output chamber and a hydraulic chamber in pairs when brake is applied and restricting the liquid transfer between the right and left wheel brake devices due to the hydraulic vibration. CONSTITUTION:The vibration which is generated in the liquid pressure of a wheel cylinder by a certain cause is transmitted to the inside of a hydraulic chamber 11 through output ports 12a and 12b. When a piston 4 shifts leftward, throttling action is generated between the hydraulic chamber 11 and the output ports 12a and 12b, and the vibration is transmitted, decreased markedly. Also the transmission of the vibration hydraulic pressure between the output ports 12a and 12b is eliminated. Therefore, resonance can be prevented by restricting the transfer of the hydraulic pressure between the both cylinders. Further, the hydraulic vibrational force while is attenuated by the throttle action can be attenuated furthermore by the action of a spring 16 and the air resistance, and the generation of the hydraulic vibration between the both cylinders is avoided.

Title: Reproducing method of sound signal
Inventor: TAKAHASHI TETSUO
IPC: H04N9/802
Filed: 1982-04-15
Abstract: PURPOSE:To reproduce the sound signal, by dividing the color carrier frequency when a low band converted color signal is reproduced, resetting the divided frequency in relation to a horizontal synchronizing signal to obtain a reproducing clock signal and reading an encoded differential sound signal out of the reproduced signal of a rotary magnetic head. CONSTITUTION:The signal recorded to a magnetic tape 7 is detected by a rotary magnetic head 6 and applied to a frequency converting circuit 23 via an LPF21 to be converted into a synthetic signal Sc of the color burst and a color. At the same time the detected signal is supplied to a pseudo horizontal synchronizing signal separating circuit 25 as well as switch circuits 26 and 29 via a BPF22 and a demodulator 24. A logical encoded differential sound signal Se is extracted by the circuit 26. At the same time, the color carrier frequency of the circuit 23 is applied to a sound clock oscillator 28 to be divided as well as to be reset by the signal related to the horizontal synchronizing signal of the circuit 25 and then supplied to a binary decoder 31 as well as to a differential demodulating circuit 34 via a time extending circuit 32 and a D/A converter 33. Thus the sound signals of left and right stereo channels can be reproduced at the output of an LPF35.

Filed: 1988-03-17
Abstract: PURPOSE:To reduce an off-set error and to obtain the fundamental function of a stable and accurate ADC by constituting an analog digital converter(ADC) and a closed loop circuit to add an operational amplifier. CONSTITUTION:In a parallel type ADC with a chopper comparator, when the off-set error of a curve (b) and a linear error shown by a curve (c) occur due to an external factor excluding the ADC, a direct current reference voltage level in an analog input edge (AIN) of an ADC 25 is corrected by a feedback loop composed of operational amplifiers 23 and 24 of a low reference voltage side (VREFL), an impedance converting buffer circuit 22 and an ADC 25. Namely, the operational amplifiers 23 and 24 are operated so as to shift in the ideal curve direction for an off-set error and a linear error. Thus, the linearity error of an analog digital converter is minimized.

Title: Matrix electrode structure
Inventor: HANDA SHIYUNJI
IPC: G09F9/30
Filed: 1978-05-24
Abstract: PURPOSE: To increase the ratio of picture elements to gaps between picture elements, by making connections between lead electrodes and picture elements via apertures of an insulating film provided between the both.  
     CONSTITUTION: The pattern of the one-side substrate of the liquid crystal display unit with picture elements of m rows by n columns is formed of lead electrodes 11, openings 12 of the insulating layer formed on the electrode, picture-element electrodes 13 formed on them, and scanning electroeds 14 and 15. In this case, openings are made over lead electrodes which correspond to every 4th picture element. Namely, N is four in this case. On the opposite substrate, picture-element electodes are made to correspond to the scan electrode parts and lead electrode 11 meet each other on the same plane. In this constitution, there is no gap except the width of the lead electrodes laterally. Therefore, the ratio of the picture-element area to the gap area is the largest and the appearance of the display becomes excellent. In addition, making the area of each display picture element equal makes it possible to reduce the entire area.

Title: Catalyst for purifying exhaust gas
Inventor: TAKESHIMA SHINICHI
IPC: B01J37/20
Filed: 1991-03-26
Abstract: PURPOSE:To obtain catalysts for purifying exhaust gas whereby even under conditions of lean-gas combustion, NOx can be efficiently reduced and purified by heat-treating zeolite catalysts having been ion-exchanged by means of transition metals in a gas stream containing sulfur compounds. CONSTITUTION:A zeolite catalyst 1 having been ion-exchanged by means of copper ions is put into, for example, an electric furnace 2 and gas 4 containing hydrogen sulfide (H2S: about 1000-10000ppm) is caused to flow from a hydrogen sulfide bomb 3. At the same time, the furnace 2 is heated by means of a heater 5 (usually to about 500-700 deg.C), so that copper oxides and the like which are attached, during ion-exchange, to an area other than a point where ion exchange is carried out and oxidized, are sulfurized to provide copper sulfides to eliminate oxidation activity. As a result, intended catalysts for purifying exhaust gas are obtained. The catalysts thus obtained eliminate catalytic action of oxides which oxidize hydrocabons, so that it is possible to accomplish purifying ratio of NOx in a NOx purification process.
