Title: Detecting device of wheel slip
Inventor: OHASHI KAORU
IPC: F02D9/02
Filed: 1984-09-18
Abstract: PURPOSE:To enable a wheel slip to be correctly detected before its generation, by deciding a wheel in a slipping condition when an arithmetic value of car acceleration, where no slip is generated in the driving wheel, is larger than a detection value of the car acceleration by a predetermined value or more. CONSTITUTION:When a vehicle is in operation, an electronic control circuit 20 first calculates car body acceleration alphaB which can be generated in a condition that no slip is caused in a driving wheel with power being transmitted from an engine 1. This car body acceleration alphaB, using driving force and running resistance calculated from an output from a throttle sensor 10, rotary angle sensor 18, etc. and the total weight of vehicle and gravitational acceleration, is calculated in accordance with a predetermined formula. And the circuit 20, deciding the wheel in a slipping condition when said car body acceleration alphaB is larger than an actual car body acceleration alpha detected by a car body acceleration sensor 26 by a predetermined value or more, prevents the generation of a slip before its occurrence by controlling driving force of the wheel in accordance with the decision result.

IPC: G06F3/038
Filed: 1985-09-09
Abstract: PURPOSE:To secure the interchangeability between a tablet and a mouse, etc. by sampling the coordinate value given from a tablet at a fixed time interval and delivering this sampled coordinate value to the relative coordinate as well as the absolute coordinates in the form of the output data. CONSTITUTION:Characters, patterns are written on a tablet 1 by means of a writing utensil like a pen, etc. A coordinate detector samples the coordinate value at a fixed time interval. The coordinate value calculated by the detector 2 is converted into the relative coordinates from the absolute coordinates by a coordinate conversion processor 3. In other words, the coordinate value obtained from the detector 2 is defined as (xi, yi) in an orthogonal coordinate system. Thus, the relative coordinates (Xi, Yi) are obtained in the orthogonal system by the arithmetic operations carried out according to Xi=xi-xi-1 and Yi=yi-yi-1. Thus, the interchangeability is secured also with a mouse, etc. that can deliver the relative coordinates through changeover of the absolute coordinates.

Title: Semiconductor integrated circuit device
Inventor: SHIBATA MANABU
IPC: H01L21/82
Filed: 1989-08-02
Abstract: PURPOSE:To increase oscillation force while maintaining high speed properties of an electric current by making a length between an idle pad corresponding to an I/O cell at a branch side and a ground line to which the ground side of each I/O cell is connected short and making idle pad potential act as ground potential. CONSTITUTION:When more than two I/O cells 2 are connected in parallel to a piece of external pad 1a, an idle pad 11a corresponding to an I/O cell 2a at a branch side and a ground line 6 to which the ground side of each I/O cell 2 is connected are connected so as to make the length between them short and potential of the idle pad 11a is made to act as ground potential. As a result, even though an electric current increases a driving force while maintaining its high speed properties, the steep current from unified I/O cells 2 and 2a flows directly to ground potential through the pad 11a corresponding to the I/O cell 2a at the branch side and its configuration makes ground impedance low.

Filed: 1985-09-09
Abstract: PURPOSE:To stably maintain a series of scaling and casing operation processes by slanting a storage boxy by a cylinder which extends and contracts with oil or air pressure and holding it at a fruit supply attitude. CONSTITUTION:The cylinder 5 extends or contacts on the basis of its fitting part to the mount table 2 of a scale 1 and when a box receiving frame 4 changes from an upright attitude to a specific slanting attitude to the mount table 2, a pressure circuit is changed to a slanting attitude maintaining circuit, so that the storage box is held at the specific slanting attitude. Then, fruits, etc., roll on the slanting internal surface of the storage box 3 to the box bottom part and are accumulated gradually. Then, as the weight of the fruits, etc., increases, oil or air leaks from a valve owing to counter pressure which maintains the storage box 3 at the slanting attitude and the cylinder extends or contracts, so the storage box 3 is stacked on the stored fruits, etc., in the process of gradual transition from the slanting attitude to the upright attitude, so that the fruits, etc., are stored. Then, the pressure circuit is changed from an upright attitude maintaining circuit to a slanting attitude maintaining circuit and this operation is repeated to stabilize automatic operation in a scaling and casing process.

Inventor: USAMI MUNENORI
IPC: G11B7/085
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device capable of accessing at high speed. SOLUTION: This device is provided with a tracking control circuit 11 for supplying a current to the tracking coil 17 of an optical head 20 and making a light spot 6, converged by an objective lens 4 elastically supported by an optical head, coincident with the track of an optical disk 5 and a traverse motor 21 for moving the optical head in the radial direction of the optical disk. At the time of seeking the optical head on the desired radial position of the optical disk by means of a traverse motor, connection of a tracking coil 17 to the tracking control circuit 11 is opened and a current, for suppressing the relative displacement between the optical head and the objective lens at the time of seeking, is allowed to flow through the tracking coil 17 from a signal generating circuit 26. The relative displacement between the optical head and the objective lens at the time of seeking is suppressed, the maximum amplitude of the free damped oscillation of the objective lens after the traverse motor is stopped becomes small and the time required for setting the objective lens is shortened. Consequently, the time until the completion of access is shortened.
