Title: Detecting apparatus for fault of wheel velocity sensor
Inventor: KAWAMURA MAKOTO
IPC: G01P3/42
Filed: 1993-07-09
Abstract: PURPOSE:To judge the fault of a wheel velocity sensor with good accuracy. CONSTITUTION:The wheel velocity sensor 1 is connected to a voltage source 3 via a resistor 2. Two connection points alpha, beta, are constituted in an electricity- feeding route between the resistor 2 and the wheel velocity sensor 1, and a voltage signal (sine waves) from the wheel velocity sensor 1 corresponding to a wheel velocity appears at the connection points alpha, beta. The time or the number of times at which a voltage value at the connection point alpha becomes continuously a prescribed threshold value or higher is counted. When a counted value becomes a prescribed value or higher, it is judged that the wheel velocity sensor 1 is faulty. When a pulse signal corresponding to the voltage signal at the connection point beta, exists, the counted value is reset to 0.

Title: Folding breaker for plate glass
Inventor: CHIYOUSOKABE HITOSHI
IPC: C03B33/033
Filed: 1994-08-18
Abstract: PURPOSE: To obtain glass plate having good cut cross section by carving a cutting line on a glass plate, raising the edge pusher whose contacting face inclines depending on the inclination of the glass plate to contact with the cutting line position and push up the glass plate until the glass is broken along the cutting line. CONSTITUTION: A cutting line 48A is carved on a glass plate 48, and an edge pusher 12 is raised from the lower side of the glass plate 48 until the glass plate 48 is break-cut. At this time, the edge pusher 12 inclines according to the inclination of the glass plate 48, when the contact face being in contact with the glass plate 48 pushes up the plate 48, and the pusher follows to the displacement of the glass plate 48. Thus, the edge pusher 12 can make the pressure from the glass plate uniform at the contact face. Further, the friction can be made small between the glass plate 48 and the contact face and the break inclination can be made smaller, thus the occurrence of inclination at the breaking position from which glass breakage starts can be reduced.

Title: Fuel cell
Inventor: MIYOSHI HIDEAKI
IPC: H01M8/02
Filed: 1986-08-19
Abstract: PURPOSE:To increase the resistance against cracks without losing the wetness of an electrolyte matrix, by composing the electrolyte matrix of a heatproof phosphoric acid type inorganic micropowder, and two kinds of binders of a fluorine resin and a hydrophile thermal-plastic resin. CONSTITUTION:An electrolyte matrix for a fuel cell is composed of a heatproof phosphoric acid type inorganic powder, and two kinds of binders which consist of a fluorine resin and a hydrophile thermal-plastic resin. By applying the two kinds of binders of a fluorine resin and a hydrophile thermal-plastic resin, the amount of the fluorine resin used for the electrolyte matrix can be reduced and its hydrophbic property is improved. And although the flexibility is low by using the thermalplastic resin alone, the flexibility is improved by reducing the amount of the thermal-plastic resin and adding the fluorine resin. Therefore, a matrix with a sufficient wetness and producing little creep or crack can be obtained.

The light sources 8 and 9 are not simultaneously lighted for plural and are successively lighted for a short time, and by continuously repeating that the display of sales possibility display and sold-out display, etc., is performed. In such a manner, even in the case that products are sold out or no cash is fed, the light source 8 for the sales possibility display or the light source 9 for the sold-out display is thinned by the interval of a set value for detection and instantaneously lighted. Though the light is almost invisible to the purchasing customer K, the purchasing customer K is detected by the photodetection sensor 11.

Title: Disk spacer
Inventor: KOMIYAMA YUTAKA
IPC: G11B23/03
Filed: 1990-07-23
Abstract: PURPOSE:To reduce the occurrence of abrasion powder due to contact for insertion to a spindle hub by forming an aluminium alloy into a ring having a rectangular section and coating its surface with a nickel-carbon dispersed composite plating film. CONSTITUTION:An aluminium alloy 11 is formed into a torus having a rectangular cross section, and its surface is ground and is subjected to pretreatment of zinc substitution and is coated with a nickel alloy film 12 by electroless nickel plating. A nickel-carbon dispersed composite plating film 13 where graphite particles are dispersed is formed by electrodeposition. Consequently, the coefficient of friction between the inner peripheral part of a disk spacer 22 and the outer peripheral part of a spindle hub 21 is reduced because of the nickel-carbon dispersed composite plating film 13 when a magnetic disk 23 and the disk spacer 22 are inserted to the columnar part of the spindle hub 21. Thus, the occurrence of abrasion powder is reduced.

This thermo module 2 comprises an internal radiator 8 and an external radiator 9, and the internal radiator 8 is fixed to a recess of the heat storage body by a heat conductive member 10. Before starting cooling operation, when the thermo module 2 is charged with electricity, because the internal radiator 8 absorbs heat, and the external radiator 9 side releases the heat, a cooling fan 13 is operated to cool the external radiator 9, and heat-absorption action of the internal radiator 8 is promoted. As a result, the heat storage body is effectively cooled by means of the heat conductive member 10.

Abstract: PURPOSE:To perform an interlayer conductive connection and an interlayer adherence by a simpler method without necessity of aligning in patterning of a polymer adhering insulating layer and in manufacture by forming the insulating layer on a whole surface including solder bumps of the opposed faces of a double-side printed circuit board. CONSTITUTION:Double-sided printed circuit boards 1, 5 have necessary through holes 4, 8, and both-side patterns 2, 3, 6, 7 on both sides. Solder bumps 9 for electrical connection are formed on the copper foils 3, 6 of the opposed faces of the boards 1, 5.

The boards are opposed at the bumps, held by upper and lower flat stainless steel plates by opposing the bumps, and heated while pressurizing. In this case, the bumps 9 are fusion- adhered while being collapsed by the pressurizing, while the layer 10 disposed thereon is removed, and bump-connection 11 is obtained. Simultaneously, the layer 10 are adhered to each other, cured at the polymer in a subsequent second stage to obtain the insulator adhesive layer 12 to complete the connection.
