IPC: F16H15/38
Filed: 1995-04-26
Abstract: PURPOSE: To provide a rolling body of less temperature dependency and excellent traction characteristic with regard to a metal made power transmission rolling body for transmitting power by means of interposing traction oil between the rolling bodies by specifying the initial surface roughness of the rolling body with respect to the average surface roughness. CONSTITUTION: Regarding a metal made power transmission rolling body used for a continuously variable transmission and the like for transmitting power by means of interposing traction oil between the rolling bodies, the initial surface roughness of the rolling body is formed so that it may be within the range of 0.1 to 0.5m by an average surface roughness Ra. By setting the average surface roughness within a specific range, traction coefficient improves in the domain of high oil temperature and temperature dependency of the traction characteristic can be drastically reduced. Such high bearing rolling body is constituted of combination of favorably a driving side rolling body and a driven side rolling body, which have recessed shape cone rolling body surfaces, and a protruded shape power roller, which rolls as being sandwiched between both cone rolling bodies.

Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To save the energy and improve the effect of dust-proofing by efficiently operating a fan while maintaining a temperature which is not problematic as regards the reliability relative to the contact glass.

Title: Semiconductor switch
Inventor: MATSUYAMA MITSUO
IPC: H03K17/567
Filed: 1990-04-20
Abstract: PURPOSE:To make the on-off detection characteristic of a main current suitable and to reduce the area occupied of an element by detecting the on-off state of a flowing current to a 1st anode terminal with a flowing current of a 2nd anode terminal. CONSTITUTION:The emitter of a transistor(TR) Q1 being a component of a PNPN switch 1 and the emitter of a TR Q51 are connected to form a 1st anode terminal A1 for the main electrode. Furthermore, the emitter of a TR Q52 whose collector and base are connected in common to those of the TR Q51 is used as a 2nd anode terminal A2 for on/off detection. The on/off detection of a main current is implemented by the presence of a current flowing to the emitter of the TR Q52 whose collector and base are connected in common to those of the TR Q51 turned finally off at the off-control. Thus, the on/off state of the main current is detected more accurately. Moreover, the TRs Q51, Q52 are integrated the same as the PNPN switch and the area occupied by the element is made small.

Abstract: PURPOSE:To apply a device to even a large-capacity and high-speed optical transmission system by determining the forbidden band width of an optical waveguide layer, the surface direction of a substrate, the polarization mode and the advance direction of an incident light, etc., and suppressing the expansion of a spectrum width due to phase modulation to modulate the intensity of light with a narrow spectrum width. CONSTITUTION:The polarization mode of the incident light, the surface direction of the substrate (the impressed direction of field), the forbidden band width of the optical waveguide layer, and the advance direction of the light are so determined that the variation of the real part of the refractive index out of variation of the real part and the imaginary part of the refractive index of the optical waveguide layer 2, which are caused when an electric field is impressed to a semiconductor external light modulator, is approximately zero. For example, if the wavelength of the incident light, the carrier concentration of the optical waveguide layer 2, the layer thickness, the carrier concentration of an upper clad layer 3, the layer thickness, and the impressed voltage of electrodes 5 and 6 are set to 1.55mum, 1X10<15>cm<-3>, 0.3mum, 1X10<15>cm<-3>, 0.1mum, and 2V respectively, a parameter alpha(DELTAnr/DELTAni) is about 0.1, and the expansion of the spectrum width due to phase modulation is almost ignored. DELTAnr is the variation of a real part nr of the refractive index at the time of field impression, and DELTAni is that of an imaginary part ni.

Abstract: PROBLEM TO BE SOLVED: To provide footgear which consists of an enhanced consolidation of an inner sole and a bottom body and which can promote the health of a person who puts it on by stimulating his/her sole in its desired position with a specified strength. SOLUTION: A number of common pin holes 3 over a wide scope of an inner sole 1 and a outsole 2, and a swelling projection 6 is furnished in the grounding surface of the outsole right under each pin hole 3. Among various inner soles having different projection patterns, a desired one 1 is selected according to the current physical condition of the person who puts it on at the applicable time, and an appropriate number of pins are inserted in the pin holes in that sole area where stimulus is to be given. The sole area can be stimulated with a specified strength by the synergetic effect of protrusions due to hardness of pins 4, the swelling projections 6 on the grounding part of the out ole, and protrusions on the surface of the inner sole 1. Because piths 4 are inserted through the common holes 3 for inner sole and outsole, their consolidation is ensured.

Title: Line drawing input device and recording medium
Inventor: YOSHIKAWA MASATAKA
IPC: G06F17/50
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To round the corner part of a line beautifully by means of a simple operation by recognizing a shape based on coordinate data of a hand-written rounding line at the time of detecting the line and correcting rounding in the corner part of the line. SOLUTION: When the line is inputted, whether corner rounding indication or not is judged. It is judged by viewing previously inputted contents stored in the line storage area of RAM 13. When the operated curvature of an approximate curve is large than a prescribed value, the hand-written rounding line is judged to be a circular arc. When the curvature is smaller than the value, the line is judged to be the straight one. When the circular arc is judged, the center and the radius of the arc are calculated. The circular arc with contact points with the line of the corner part as a drawing end is calculated based on a center coordinate and the radius obtained in this way and displayed by superimposition on the corner line. Then, the line in a part of the corner is erased.

Abstract: PURPOSE:To facilitate an operation by storing a management table to record a file name on an optical disk and a magnetic disk 7 and the volume name of the optical disk on the magnetic disk and copying the file to store the management table onto the optical disk when prescribed conditions are satisfied. CONSTITUTION:Since the file name on a magnetic disk 203 and the file name and a medium name on an optical disk 205 are recorded onto the management table of a file managing device 202 at the time of executing an unload processing, a trouble for a man to note the file name onto paper is made unnecessary. Simultaneously, since the management table is managed by a computer, the competition of the file names on the optical disk 205 which is a conventional problem can be evaded. The searching of an aimed file can be facilitated, and the management table is copied onto the optical disk 205 when the prescribed conditions are satisfied. Thus, even when the dissipation of management information due to an unexpected accident is generated, a damage can be minimized.
