Title: Speed control system for mechanical type continuously variable transmission
Inventor: MIKAMI YOSHIAKI
IPC: F16H61/02
Filed: 1991-11-15
Abstract: PURPOSE:To perform stable and highly accurate speed control by changing the output period of speed change signals in simple increase according to the quantity of deviation in performing the feedback control of a speed change means according to the deviation of the actual revolution of a stepless speed change gear from the objective revolution. CONSTITUTION:In the case where a mechanical type continuously variable transmission 1 is rotated by a motor 2 for rotation, the waveform of a output revolution pulse signal detected by a magnetic sensor 8 is input in a micro computer 12 after being reshaped by a waveform reshaping circuit 10. The number of the detected pulses included in the output cycle Tz of the timing signal Sz from a timing controlling section 18 is counted by a counter 14, and the value is given to a actual revolution calculating section 18. In this section, actual revolution Sm is calculated from the value obtained by counting. In the next step, deviation (e) from objective revolution So is determined by a deviation operation section 20. The rotation direction and conduction period Tn of a reversible motor 4 are controlled according to this deviation (e). At this moment, the conduction period Tn of speed change signal Sn is changed in simply increase according to the deviation (8).

Title: Manufacture of polycrystalline thin film
Inventor: AKIMOTO KOICHI
IPC: H01L21/203
Filed: 1987-11-27
Abstract: PURPOSE:To form a polycrystalline thin film where its grain boundary is superior in bonding strength, by forming fine irregularity faces of a substrate where the polycrystalline thin film is vaporized and causing the angle made by the above faces to agree with the angle made by the specific crystal faces. CONSTITUTION:If each face of irregularity faces attains the size of a crystal grain, only a piece of grain grows in each face of the irregularity faces. Once the angle made by the above faces agrees with the angle made by the specific crystal faces, the crystal grain grown on its face is joined to a grain which is adjacent to the specific crystal face. For example, an Al film is formed by a spattering process on an Si substrate where an SiO2 film is formed by thermal oxidation. The highest protruding part at the substrate is composed of places where only peaked lines 2 gather and the lowest recessed part of the substrate is composed of places where trough lines 1 gather. The length of each side at each face of the irregularity faces is 1mum. The angle made by faces is the angle: 70.529 deg. that is made by crystal faces (111). The irregularities are formed by irradiating an electron beam 1kW at an angle by using Ta as a mask.

Thus, the space of a sharp image without a shadow and unevenness can be obtained. In addition, the defective separation of a transfer material from a fixing roll can be prevented, and a high quality image can be formed. Since this device does not employ a sub- exposing means, etc., its structure is simple, which contributes to easier assembly and low costs.

Title: Circuit for compositing gaseous substance image
Inventor: IKEDO TSUNEO
IPC: G06T19/00
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To attain a real-time display that is essential for the drawing of a virtual reality system by multiplying the luminance of every substance by a value that is obtained from a distance function and the compositing permeation value for deciding the new composite luminance of a gaseous substance and a planar definition substance. SOLUTION: A gaseous substance has a luminance Ig, a visual axis point Z0 and the permeation value Ag, and a plane definition substance has a luminance Is and a visual point Z1. The visual point coordinate values Z0 and Z1 are subtracted from each other via a subtracter 7a, and this difference value dZ is outputted. For the luminance, a value selected by a multiplexer 11 is multiplied by the output value of a table 9 via a multiplier 8c. This multiplied value is then multiplied by the luminance Ig and Is through the multipliers 8d and 8e respectively and then added together via an adder 10b. Thus, a final luminance Ip is obtained. The outputs of the multiplier 8e are inverted by a subtracter 7b and then added. The composited luminance obtained in this a way is displayed directly, after being stored in another image memory.

Abstract: PROBLEM TO BE SOLVED: To utilize an instrument panel for various kinds of machines by displaying the sensor information that an on-vehicle controller obtains on an instrument panel with storage device, storing the information and making this instrument panel mountable on an other vehicle. SOLUTION: The instrument panel 20 as a data collector is connected so that the panel may be communicated with a controller and is composed so that it may be freely attachable/detachable to a combined main machine.

When a work interruption switch 30 is depressed at this time, the processings based on the switches are performed. When a work termination switch 31 is depressed, the data written in the RAM is transferred to the controller and is subsequently stored.  When this instrument panel 20 is mounted on another type of machine, a communication connector part 39 is removed from the insertion part of the front part of a steering seat and the instrument panel is used by being inserted into another type of connector.
