Title: Hall floor device of cargo elevator
Inventor: KANAI KEISUKE
IPC: B66B13/30
Filed: 1994-03-30
Abstract: PURPOSE:To prevent the fork of a fork lift from contacting a hall threshold by furnishing a protective steel plate having a triangular section projecting part protruding from the hall floor surface of a cargo elevator and embedded in the hall floor parallel with a threshold to guide the hall door. CONSTITUTION:A fork lift 9 carries out an object 11B loaded on a pallet 11A which is placed in a cargo elevator car 10. When a hall door 3 and car door 10A are opened, the operator 7 sinks the fork 9A to the bottom and approaches to the car 10. Despite contacting a protective steel plate 6, the tip of the fork 9A is heaved because the steel plate 6 is inclined upward. The steel plate 6 has a triangular section protruding from the hall floor surface and prevents the tip of the fork 9A from contacting the threshold 4. Eventual contacting of the tip of the fork 9A with the steel plate 6 does not lead to dislocation of the embedding position or breakage because the forces acting on the steel plate 6 are dispersed owing to its gradual inclining upward.

IPC: H02P29/00
Filed: 1988-03-14
Abstract: PURPOSE:To cope with deterioration with age of the title device by securing such constitution where a control means controls the gain of a servo system via a gain control means at the time of detection of the start of working to automatically obtain the secondary resonance frequency and the resonance value of a mechanism system and actuating a notch filter based on these obtained values. CONSTITUTION:At the time of detection of the start of working, a control means 12 controls the gain of a servo system via a gain control means 11 to obtain the secondary resonance frequency and the resonance value of a mechanism system. Then the means 12 actuates a notch filter 3 contained in the servo system based on those obtained resonance frequency and value. As a result, the center frequency and its resonance value of the filter 3 are automatically controlled by self-learning actions so as to secure previously accordance with the secondary resonance frequency and the resonance value of the mechanism system. Then the servo control is ensured hereafter during a steady action based on said frequency and value of the filter 3. Therefore, the control of the filter 3 is not required for each product put on a production line despite the variance of parts of the mechanism system. Thus it is possible to cope with the deterioration with age of a servo device for an optical disk driver.

Title: Radio channel changeover method
Inventor: KUNO YUTAKA
IPC: H04W36/22
Filed: 1995-03-20
Abstract: PURPOSE: To provide the radio channel changeover method in which communication quality is quickly recovered by a method suitable for a state of a point of time when the communication quality is deteriorated. CONSTITUTION: A reception level of an interference wave coming from a peripheral cell is measured in the step SA1. A total number (n) of radio channels where a reception level of the interference wave is a prescribed level or over is obtained in the step SA2. An in-cell/inter-cell channel switching level K is calculated based on a prescribed equation (K=K0 -a×n) in the step SA3. When deterioration in communication quality is caused (step SB1), whether or not a reception level of a desired wave is the in-cell/inter-cell channel switching level K or over is discriminated in the step SB2. When the result of discrimination is affirmative, the in-cell channel changeover is conducted (step SB3). On the other hand, when the result of discrimination is negative, the inter-cell channel changeover is conducted (step SB4).

Abstract: PURPOSE:To ease the limitation for the format of additional segments when a drawing is produced by performing drawing reading processing so as to attain detection and separation of a dimensional auxiliary line and an exterior line even in case both lines are connected to each other. CONSTITUTION:A drawing on an X.Y table (a) is picked up by a camera (b) and this pick-up output is supplied to a CPUe via an input circuit (d).

This decision is continued until the type of the feature point is not equal to the feature point of the arrow mark, that is, said feature point reaches a feature point on an exterior line. A point where the feature point reaches the feature point on the exterior line is decided as a contact between dimensional auxiliary line and the exterior line. Then the segment led up to the contact is detected and deleted and all segments having terminal points are processed.
