Title: Driving circuit for capacitive load
Inventor: KOJIMA KAZUMI
IPC: H03K17/13
Filed: 1987-08-20
Abstract: PURPOSE:To make the size of driving power supply small by connecting the driving power supply, a switching element, an inductance element and a capacitive load in series, and switching timely the switch element while monitoring a voltage of the capacitive load thereby charging/discharging the capacitive load very efficiently. CONSTITUTION:A control circuit S controls a circuit where the driving DC power supply 1 having a voltage VS, a reed relay 2, a coil 3 and the capacitive load 4 are connected. Then an external control signal SI with a high level commands the charging of the capacitive load 4 and that with a low level commands the discharging. An operational amplifier A1 of the control circuit S forms a differentiation device together with a capacitor C3 and a resistor R3 and its output is VD. When the differentiation output VD being the result of differentiating and inverting the charging voltage VC is again '0', the reed relay 2 is opened. Then the driving circuit for the capacitive load 4 has only the reactive element only in case of both charging and discharging. Then the energy is not consumed and the energy charged in the capacitive load 4 is regenerated all to the power supply at the time of discharging.

Abstract: PURPOSE:To obtain a charge amplifier of simple constitution and low power consumption, by using a source follower circuit, whose power consumption is low and which is connected to a common bus, and forming the device by an MIS constitution. CONSTITUTION:An insulating film is arranged on a semiconductor substrate 51. On  said insulating film, a containing electrode GG which contains a specified amount of the charge, a transfer electrode GT, a storage electrode GR, a barrier electrode GB, and a detecting electrode GO are sequentially arranged. The area of the storage electrode GR is made larger than the area of the detector electrode GO. Specified  timing pulse voltages are applied to the containing electrode GG and the transfer electrode GT, thereby moving a potential level directly beneath both electrodes up and down. When the contained charge directly beneath the containing electrode is transferred to the part directly beneath the detecting electrode, a part of the charge, which is transferred by the potential level beneath the barrier electrode that is controlled so that the potential level is shallower than the potential level directly beneath the storage electrode, is made to remain at the part directly beneath the storage electrode. The rest of the charge is flowed into the part directly beneath the detecting electrode. The amplified charge, which corresponds to the capacity ratio of the detector electrode GO and the storage electrode GR, is taken out as an output voltage.

Title: Magnetic disk device
Inventor: MIYAZAKI OSAMU
IPC: G11B21/10
Filed: 1986-09-03
Abstract: PURPOSE:To prevent the lowering of accuracy of positioning by writing the positioning information of a magnetic head in a data recording face that makes the amplitude of reading signal of the magnetic head maximum out of the plural combinations of magnetic head/data recording face. CONSTITUTION:The width TW of positioning information written alternately in A pattern section and B pattern section of positioning information writing areas between all data recording tracks is determined by the track width of a magnetic head, and the amplitude of reading signal of the magnetic head is nearly proportional to the track width of the magnetic head in the combination of magnetic head/data recording face. The positioning error due to the vertical difference of the direction of the spindle shaft caused by miniaturizing the device and reforming structure etc. is suppressed to a low level, and accordingly, the positioning information is written in the data recording face of large reading signal amplitude of the magnetic head out of the plural combinations of magnetic head/data recording face. Thereby, the positioning information of wide TW and large reading signal amplitude is obtained, and the lowering of accuracy of positioning can be prevented.

Filed: 1990-08-08
Abstract: PURPOSE:To constitute the driving device of a cutting mechanism so that a small output is enough and to simplify this device constitution by generating a cut line in a scored line in the transverse direction of a part first, propagating the cut line concerned in the seat paper width direction and cutting the paper, at the time of cutting the seat paper. CONSTITUTION:Projecting parts of cutting cam bodies 74-84 of a driving shaft 72 hold seat paper therebetween with rollers 94-104 of a driven shaft 62 and apply tension to the paper. In this case, the projecting parts of the cam bodies 74, 84 placed on both end sides of the driving shaft 72 hold the paper therebetween by preceding projecting parts of other cam bodies 76-82 and give tension to the paper, so that the scored line starts to be torn partially. Once a cut line goes into the scored line, this cut line is extended easily in the transverse direction of the paper, therefore, succeedingly, when the projecting parts of other cam bodies 76-82 and the rollers 94-104 hold the paper therebetween and give tension to other part of the scored line of the paper, the seat paper is cut quickly along the scored line concerned. Accordingly, in the initial time for cutting and even in the succeeding middle time or the latter time for cutting, as for necessary driving force, small force is enough.

Title: Catalyst for purifying exhaust gas, its production and production of honeycomb catalyst for purifying exhaust gas
Inventor: TAKEMOTO TAKASHI
IPC: B01J29/06
Filed: 1994-09-01
Abstract: PURPOSE:To decompose NOx in an exhaust under the presence of a reductant such as hydrocarbons even in an oxygen-excess atmosphere by adding Al2O3 or CeO2 as a cocatalyst to a catalyst in which noble metallic active species are deposited on the metal-containing silicate to shift NOx eliminating active temp. of the catalyst to a high temp. side. CONSTITUTION:Al2O3 or CeO2 as the cocatalyst is added to the catalyst in which the noble metallic active species are deposited on the metal-containing silicate, for example, aluminosilicate (zeolite). Pt, Rh, Ir and Pd which are considered generally to have a low temp. activity are suitable as noble metals, and Pt is suitable especially in the view point of the low temp. activity of the catalyst, and these noble metals may be used in combination. A case in which both Al2O3 and CeO2 are added, and wt. ratio of Al2O3/CeO2 is 0.1-10 is exemplified as a suitable example of the cocatalyst. In this way, an active temp. can be shifted to a high temp. side, moreover, improvement of the heat resistance without substantially decreasing the max. NOx purifying efficiency is advantageous.

Abstract: PROBLEM TO BE SOLVED: To evaluate the shape of a front and/or a rear surface of a semiconductor wafer accurately and quantitatively, by measuring the shape of a front and/or a rear surface of wafer, and performing frequency analysis for a profile thereof. SOLUTION: The shape of a front and a rear surfaces of a semiconductor wafer before and after vacuum suction is measured by an optical shape measuring device, etc., by using a mirror polishing wafer of different rear finishes. Frequency analysis of the measured profile such as amplitude and power spectrum analysis is carried out and influence from the rear to the front shape for each spatial frequency is evaluated quantitatively. As a result, it can be recognized quantitatively that roughness of a rear of a semiconductor wafer and influence to an irregular front shape are different for each spatial wavelength. Therefore, it is possible to select and manufacture a semiconductor wafer which is free from undulation element which becomes a problem in photolithography, isolation, etc., in a device process caused by transfer of undulation element of a wafer rear to a front.
