Title: Grinding machine
Inventor: SEO HIROMICHI
IPC: B24B7/02
Filed: 1986-02-19
Abstract: PURPOSE:To make the extent of finishing surface roughness on the top of a workpiece improvable even in case of a general purpose grindstone being relatively rough in grain size, by forming a grinding lower surface of the grindstone on a taper surface to go up outward in a radial direction of the stone. CONSTITUTION:A workpiece W on a support table 7 is shifted relatively in a horizontal direction to a grindstone 22 by operation of a feed motion 5, and an upper surface of the workpiece W is ground with the specified infeed depth. At this time, the grindstone 22 is supported on a support block 13 with a turning axial center in a rectangular direction to the top of the support table 7, and the grinding lower surface 16a is formed on a taper surface to go up toward in a radial direction of the grindstone 22. Therefore, on top of the workpiece W, most of portions for the specified infeed depth are ground by a peripheral surface of the grindstone 22, and the remaining parts are gradually finished into smoothness as the grinding lower surface 16a is being round. Therefore, even if such a general-purpose grindstone that is relatively rough in grain size is used, the top of the workpiece W is ground into such a finishing surface that is improved in surface roughness.

Title: Input/output control system
Inventor: SHIHARA SHINJI
IPC: G06F13/12
Filed: 1990-02-15
Abstract: PURPOSE:To miniaturize a device without degrading the performance of input/ output control by mounting plural input/output control parts on one substrate and independently performing communication between these control parts and a central processing unit through a pair of bus control parts. CONSTITUTION:When initialization is instructed to a bus control part 3 from a central processing unit 1, a first initializing part 8a initializes a first input/ output control part 11 and instructs initialization to a second initializing part 8b. The second initializing part 8b reports the end of initialization to the first initializing part 8a after initializing a second input/output control part 12 by this initialization instruction. When the initialization processing of the first initializing part 8a is terminated and the end of initialization is reported from the second initializing part 8b, the first initializing part 8a reports the end of device initialization to the central processing unit 1. Thus, the input/output device can be extended without increasing the number of bus control parts 3 without degrading the input/output control function.

Abstract: PURPOSE:To utilize a surface wave in the SH mode and to form plural attenuation poles with a single element by forming an interdigital transducer so as to have at least two resonance characteristics. CONSTITUTION:An interdigital transducer (IDT) 15 comprising interdigital electrodes 13,14 is formed on a front side of a piezoelectric substrate 12. Each of the interdigital electrodes 13(14) has plural electrode fingers 13a-13d(14a-14i). Then a BGS wave propagated in a direction orthogonal to a direction in which the electrode fingers 13a-13d(14a-14i) are extended is stimulated in a piezoelectric resonator 11 by applying an AC voltage to the interdigital electrodes 13, 14 similarly to the case with the conventional end face reflection type surface wave resonator utilizing a surface wave in the SH mode, and the BGS wave is reflected between end faces 12a and 12b. Thus, two resonance points Fr1, Fr2. appear in the piezoelectric resonator 11 as above and then two resonance characteristics are obtained.

Title: Self loading cartridge
Inventor: SAKAGUCHI TADAHIKO
IPC: G11B23/027
Filed: 1988-02-17
Abstract: PURPOSE:To prevent the looseness and the Z-shaped bending of a magnetic tape and to improve reliability by providing a half arc shaped nonskid material to interlock with the opening and closing of the entrance of a case to house the magnetic tape and press the outer circumference of the magnetic tape when the entrance is closed. CONSTITUTION:When an entrance 4 is closed in an opening and closing operating part 5, a nonskid material 2 keeps a fixed height in a direction to the center part of a case 1, has a half arc shape, and abuts on the outer circumference of a magnetic tape 7. Consequently, the skidding (rewinding) of a tape 7 is suppressed by the constant pressure of the nonskid material 2. On the other hand, when the entrance 4 is opened, a part fixed by an opening and closing lever 6 is lowered to a lower part, and the nonskid material 2 is changed from the half arc shape to a flat state and never prevents the rotation of the tape 7.

Abstract: PROBLEM TO BE SOLVED: To form an i-type non-single-crystal silicon layer with improved electrical and optical characteristics by constituting the i-type semiconductor layer with the non-single-crystal semiconductor layer and making non-uniform the distribution of the average crystal particle diameter of the crystal particles of the i-type semiconductor layer. SOLUTION: A photovoltatic element consists of a substrate 101, an n-type semiconductor layer 102, an i-type semiconductor layer 103, a p-type semiconductor layer 104, a transparent electrode 105, and a current collector electrode 106. A group IV element and a group IV-alloy non-single crystal semiconductor material are used as the semiconductor material. The semiconductor layer is doped to p and n types by a valence electron control, thus forming a pin junction. A plurality of pin junction are laminated, thus constituting a stacked cell. The distribution of the particle diameter of crystal particles being present in the i-type semiconductor layer is not uniform in film thickness direction and/or in surface direction, thus improving light absorption in the i-type semiconductor layer and increasing a light generating current.  Also, the surface level density is reduced and the recombination of the light generating carriers is suppressed.

Title: Small surface vehicle
Inventor: TAOMO MITSUHARU
IPC: B63B35/73
Filed: 1986-02-18
Abstract: PURPOSE:To select a moving locus separately from a towed object for cruising for a long time by providing a guide bar continued between both sides of a ship at the rear of a bow end and in front of the center of gravity of a hull and fitting a towing rope movably along this guide bar. CONSTITUTION:With a roller 6 located at the center in the ship width direction of a guide bar 5, when a towing rope 2 is pulled, a hull 1 cruises via its towing force. Since the guide bar 5 is normally inclined forward, the roller 6 is moved to a keel section, and the hull 1 is towed in the straight direction. When a person 10 operates a rudder 3 via the operation of a handle 4, the cruising locus can be changed outside the locus of a towed object. When the moving locus of the hull 1 is changed, the towing rope 2 faces the side direction from the hull center line, thereby the roller 6 is moved along the guide bar 5, and the towing point is moved to the inclined direction of the towing rope 2. Accordingly, the hull 1 is allowed to cruise outside the locus of the towed object.

Title: Flat plate type optical fiber cable for branching
Inventor: YAMAZAKI YASUSUKE
IPC: G02B6/00
Filed: 1987-02-18
Abstract: PURPOSE:To permit easy post-branching by providing a surplus length forming part to an optical fiber core. CONSTITUTION:A tensile body is embedded in the major axis end of a flat- shaped sheath 3 and the optical fiber core 2 to be housed into the sheath 3 is provided with the arc-shaped surplus length forming part and is made into the structure to have the surplus length at the time of branching and connection. Since the tension during laying of the cable is supported by the tensile body 1, the arc-shaped surplus length forming part formed to the optical fiber core 2 is prevented from being elongated at the time of laying. If the need for the post-branching after the laying arises, the cable is cut at the required point and the inside optical fiber core 2 is drawn out to elongate the arc-shaped surplus length forming part to a straight shape. The surplus length required for the connection is thereby obtd. The easy post-branching requiring reconnection after the laying is thus permitted.
