Title: Throttle control device for vehicle
Inventor: SUGIURA KEISUKE
IPC: F02D29/02
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To provide a throttle control device which can prevent the overshoot of car speed only by throttle control to realize the smooth running of a car. SOLUTION: A control device obtains a difference between present car speed detected through a car speed sensor and target car speed decided according to the operation quantity of an accelerator, and drives a throttle motor (actuator) according to the above difference to control throttle opening. In the case where the throttle is opened more than the set opening, the target car speed is once set up to a target ceiling car speed V lower than a limit car speed Vmax (the maximum set car speed), and when the present car speed arrives at a medium car speed Vm which is set up the same as the target ceiling car speed or smaller than that value, the target car speed is gradually increased to the limit car speed Vmax .  Thus, in the case where the accelerator is wholly opened to start the vehicle, since the target car speed is gradually increased to the limit car speed Vmax from the time when the present car speed arrives at the medium car speed Vs , the present car speed is also gradually increased to the limit car speed Vmax , and overshoot is thereby prevented.

Title: Metallic material with optical film
Inventor: WAKUMOTO MASANOBU
IPC: C23C28/00
Filed: 1987-12-23
Abstract: PURPOSE:To enhance the reliability of an optical film by interposing metallic film or a metal compd. film the degree of combination of which does not yet attain a prescribed degree of combination between the optical film and a metallic base material, thereby providing the secure surface. CONSTITUTION:An underlying film, the degree of combination of which does not attain the prescribed degree of combination means that properties of the film consisting of, for example, a metal compd. of titanium and oxygen are nearer the properties of the metal compd. as the ratio of TiO2 is higher, i.e., as the degree of combination is nearer the prescribed degree of combination and said properties are nearer the properties of the metal alone as the ratio of the TiO2 is lower. The underlying layer 4 is, therefore, interposed and is securely adhered to the metal base material 2 with the result that the multilayered optical films are securely adhered to the metallic base material 2 and the reliability is enhanced. The extremely secure surface is thereby obtd., by which the adhesive power between the optical film 3 and the metallic base material 2 is enhanced and the reliability of the optical film 3 is improved.

Abstract: PURPOSE:To enhance the accuracy of position detection and reduce the cost of an elevator control device without deteriorating rescue operation functions by providing means for correcting the content of each memory element for the lowest floor to a reference floor according to a value detected when a cage arrives at the reference floor and to a second reference value. CONSTITUTION:Microcomputers 1A, 1B input reference values CO, CR which correspond, respectively, to the lowest floor MF-2 and a reference floor MF, to respective counters 3A, 3B according to preset specification data. When a counted value (x) is judged to be at the level of the reference floor MF, a CPU sets the reference value CR for the reference floor MF to the counter 3A as a count value. Also, the difference (e) between a count value (x) before correction and the reference value CR is calculated and the reference value CR is written on a memory element P(MF). Thereby the count value in a memory buffer (x) is renewed by the reference value CR and the level of each floor number (m) is corrected to the level of the counted value by subtraction of the count difference (e).
