Abstract: PURPOSE:To carry out sheets surely one by one from a cassette without giving damage on layers of chemicals on the surface of the sheets by providing suction cups on a member reciprocating between a paper transfer roller and a cassette for housing sheets. CONSTITUTION:When suction cups 10, 10 are abutted on a developed sheet, they 10, 10 are press-contacted to the surface of the sheet for sucking the sheet. Under this condition, a pulse motor 1 is rotated reversely, but after the elapse of a fixed time it is rotated normally for making a link mechanism 18 move upwards once, next to ward rollers 3, 5.

Title: Processing of opening synthetic signal
Inventor: IKEDA NAOAKI
IPC: G01N29/06
Filed: 1987-01-14
Abstract: PURPOSE:To reduce processing time, by performing an opening synthesization processing only for a data within a directional angle of an ultrasonic sensor while a data within a specified range is calculated beforehand. CONSTITUTION:An imaging area 2 is set to include a reflection source 1 and scanned with an ultrasonic sensor 3. Reflection echo is digitized and an image memory is divided into meshes beforehand. When a waveform data is added to an imaging area memory, a reflection echo is added up to a part c-c' at a sensor position S1 and to a part d-d' at a sensor position S2 considering the directivity of the sensor 3. The same processing is performed for each of sensor positions. Ultrasonic wave propagation time is calculated at points between meshes and sensors to be stored into an array as data set. This enables the avoiding repetition of the same calculation, thereby assuring a reduction in the calculation time for signal processing.

Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method of a resin molding with skin, with which a large compressive force becomes unnecessary, no skin material damages, the flow balance of a molten resin is ensured with a good reproducibility, a mold is simplified and a skin material is easily installed onto the mold, and the resin molding with skin.

After the mold 2, on which the skin material is installed, is closed and the movable mold 4 is advanced to a second position β, the injection of a molten resin 3 is started and then the movable mold 4 is advanced again. As a result, the recess becomes shallow and no large compressive force becomes necessary even when the molten resin 3 enters this recess, resulting in not damaging the skin material. In addition, since no reversion of a position between a cavity and a core occurs, a favorable flow balance of the molten resin 3 is realized.

Title: Oil pressure control mechanism for marine reduction and reversing gear
Inventor: HARADA KAZUYOSHI
IPC: F16D48/02
Filed: 1993-01-19
Abstract: PURPOSE:To avoid a shock at engaging a hydraulic clutch so as to quickly engage it by adjusting working oil pressure according to the rotating speed of a propeller. CONSTITUTION:Until the rotation of a propeller shaft 17 becomes NP1 (for example 50rpm), the oil pressure is kept at P3 (3-4kg/cm<2>), and when it is NP1, the oil pressure is lowered to P2. When a clutch is completely engaged and the rotation of the propeller becomes 80%, the oil pressure is finally set at P1. The oil pressure is set as P1>P2>P3. Simultaneously at start, it is judged whether engaging switches are ON or not, by means of an ahead clutch engaging sensor 7 and an astern clutch engaging sensor 8. Next in the case of the engaging switch ON, it is judged whether the rotating speed of the propeller is higher than NP1 or not. When the propeller rotating speed is lower than NP1, the oil pressure is set as P3. In opposition, when the propeller rotating speed is already over NP1 and lower than (NE/iX0.8), the oil pressure is set as P2.
