IPC: G11B17/32
Filed: 1986-12-17
Abstract: PURPOSE:To obtain the narrow spacing of wide range where high bit density can be attained without damaging a recording medium by making a groove, which forms a wide width sliding surface and a thin width sliding surface obtained by separating them, a groove which generates a positive pressure with the flow of a fluid. CONSTITUTION:One magnetic head slider has the wide width sliding surface 2 provided in parallel with the thin width sliding surface 1, a positive pressure groove 3 and a positive pressure notch 4 provided adjacently to the thin width sliding surface 1 and on the wide width sliding surface 2 a magnetic core 5 is arranged in a position where the thin width slider of another opposite magnetic head slider is arranged. A pair of magnetic head sliders are arranged with putting the recording medium 8 between them in the position the thin width and wide width sliding surfaces are opposite each other through a supporting mechanism which presses from at least one direction. When the recording medium 8 runs in the direction of an arrow A the positive pressure groove 3 and the positive pressure notch 4 generates the pressure higher than the circumference with the aid of the airflow which flows along the recording medium 8 and the recording medium 8 is pressed to the wide width sliding surface 2 opposite to it. Thus, recording gap between a magnetic core and a magnetic medium becomes extremely narrow, so that the high bit density can be possible.

Title: Heat exchanger combined with supply air filter
Inventor: OCHI YASUO
IPC: F28F3/00
Filed: 1985-12-27
Abstract: PURPOSE:To obtain a compact heat exchanger combined with supply air filter, by performing purification of feed air and exchanging of heat of feed air with exhaust gas at the same time. CONSTITUTION:Filters 2 and fins 3 are alternately laid interposed by metallic bulkheads 1. In the primary flow passages 4 for supply air, the inlets 6 formed by the recessed sections and outlets 7 formed by the protruded sections of filters 2 are closed by sealing materials 8. The air being fed from the inlets of protruded sections once passes through the filters 2 as shown by arrow signs A, and flows out of the outlets of recessed sections after dust is filtered from the air. When a boiler is set to operation, a fan is driven and combustion air is fed to a surface-combustion burner through the primary flow passages 4 of a heat exchanger. Exhaust gas produced by the surface- combustion burner is heat-exchanged with combustion air in the secondary flow passages 5 of a heat exchanger, and is discharged to the outside of the passage 5. At that time, the air flowing through the primary flow passage 4 of a heat exchanger is fed to the neighboring flow passages on the opposite side through the filters 2. The air is cleaned and at the same time the heat is recovered from exhaust gas by the air contacting to exhaust gas and contacting to the bulk-heads 1 which are heated by the heat transmitted from the fins 3.

IPC: G02B7/08
Filed: 1988-11-26
Abstract: PURPOSE:To maintain a focusing state at the time of zooming by calculating the position relation between a power varying lens group and a compensating lens group in zooming operation from the position information obtained when both the lens groups are in the focusing state. CONSTITUTION:The position relation between both the power varying lens group 2 and compensating lens group 4 is calculated in a form approximated by an equation of degree (n) from the position information on both the lens groups 2 and 4 when the photographic lens which includes both the lens groups 2 and 4 is in the focusing position. Namely, when a zoom curve is obtained from the position information on the variator lens group (V lens group) 2 and rear relay lens group (RR lens group) 4, the lens group positions are moved by a microcomputer, etc., along the curve to eliminate blurring in the zooming operation. Consequently, the blurring due to the response delay, etc., of an automatic focus detecting device is reduced.

Title: Lead frame and its manufacture
Inventor: MATSUNAGA HITONORI
IPC: H01L23/50
Filed: 1989-11-20
Abstract: PURPOSE:To obtain a tab lowering frame excellent in view point of the effective use of plane space by removing the insulation space in plane direction between the top of each inner lead in all directions and the periphery of a lowring tab. CONSTITUTION:On the plan view, there is little interval between the top of each inner lead 1 in all directions and the periphery of a tab 2, so it turns out that the area of the tab 2 has increased only by the part outside a broken line. This part corresponds to the groove in an etching method or the punch width in a stamping method, and the tab 2 at large is pushed down by the distance above the thickness of each inner lead 1, and the insulation between the tab 2 and each inner lead 1 is maintained by the vertical interval. Hereby, the effective utility of the plane space of a lead frame is enhanced and the external package of a semiconductor device can be shrunk.

Title: Information processor
Inventor: MATSUMOTO KOJI
IPC: G06F1/00
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To decrease the amount of data, which are to be written into a non- volatile storage device, and to enable transition to a suspend disk state at high speed by storing only the state of a disk, for which a preservation flag is turned off, and cutting off power supply when power supply cutting-off is instructed while the state of the disk is different from a stored state. SOLUTION: When an information processor is turned into idle state, concerning all devices 7, it is discriminated whether the device 7 is in the idle state or not. Then, it is judged whether the state of the device 7 registering a number on a device list 5 is already preserved or not. The states of all the devices 7 remained on the device list 5 are preserved in a non-volatile storage device 3. Thus, since the devices 7 in the idle state are sequentially reserved in the non-volatile storage device 3, when the suspend is instructed by the power cutting-off instruction, it is enough only to store the state-changed device 7.

Filed: 1991-10-18
Abstract: PURPOSE:To prevent noise generated from an output buffer from causing the malfunction of an input buffer in the case of the output mode of a bidirectional buffer. CONSTITUTION:An input buffer 2 for an input mode and an input buffer 3 for an output mode are prepared and a control signal for switching the mode switches the two input buffers 2, 3. A Schmitt trigger buffer is adopted for the output mode input buffer. However, an input to the output mode input buffer 3 is given from the input terminal A of the bidirectional buffer directly not through the output buffer 1 and a control signal is used for switching the two input buffers 2, 3, then any Schmitt trigger type buffer is not required.

Abstract: PURPOSE: To make a subband encoding system applicable to the band compression of luminance signals of high-fidelity television by making a low-frequency domain evenly dividable. CONSTITUTION: The frequency band of input signals is divided into high-frequency components and low-frequency components in two-dimensional diagonal directions by means of filters 151 and 142 and the low-frequency components are further divided into high-frequency components and low-frequency components in the orthogonal directions. The diagonal and orthogonal high-frequency components are once encoded and the orthogonal low-frequency components are continuously divided until the components become an arbitrary size by repetitively performing the dividing process so that data can be compressed more effectively.
