Title: Elevator hall device
Inventor: FUWA SEIJI
IPC: B66B13/30
Filed: 1993-11-15
Abstract: PURPOSE:To provide an elevator hall device which can prevent generation of turbulent air flow between a car and a hall entrance when the car passes by the hall entrance. CONSTITUTION:Baffle plates 8 are provided at a hall entrance, facing the frontage of a car elevating through a shaft, being extended upward while the lower ends of the baffle plates 8 are located at the shaft side edge of a threshold 3. With this arrangement, aheight difference at the upper surface of the shaft side projecting edge part of the threshold 3 can be reduced. Accordingly, turbulent air flow which occurs when the car passes by the hall entrance can be decreased so that unsatisfactory noise caused by this turbulent flow can be reduced. Thereby it is possible to provide a calm environment around a building incorporating an elevator.

Inventor: HOSODA MICHIYOSHI
IPC: A01B33/02
Filed: 1992-09-30
Abstract: PURPOSE:To save the labor by making it unnecessary to operate a handle for controlling the depth of plowing up and down. CONSTITUTION:Simultaneously with plowing rotation of a tillage rotor 4, a cultivation-wheel 7 equipped with plural projections 9 is driven to be rotated at a constant very slow speed. The machine body 1 is moved forward by the cultivation wheel 7 at a constant very low speed.

The running resistance is mostly loaded on a resistance rod 10 and the load on the cultivation wheel 7 is small. Therefore, a large load is not given also to a speed reduction system for driving the cultivation wheel 7 and the speed reduction system can be designed so as to be simple.

Title: Solid state image pickup element
Inventor: KOIKE NORIO
IPC: H04N5/335
Filed: 1985-12-20
Abstract: PURPOSE:To prevent the occurrence of flake flaws and printing after images, by burying a gap between electrodes with an insulator, and flattening a scanning IC substrate. CONSTITUTION:A region 12 corresponding to a gap between picture element electrodes 7 is buried by an insulator layer 13, whose thickness is about the same as the thickness of the electrode 7. Thus the stepped part due to the electrodes 7 is hardly present. Therefore, a photoelectric conversion film 8 is uniformly formed on the upper part of a scanning IC substrate. As a result, withstanding voltage of the photoelectric conversion film 8 becomes uniform in the entire body. The occurrence of leaking type flake flaws can be reduced. Since the photoelectric conversion film is not present in the gap part 12 between the electrodes, printing after images can be reduced to a large extent.

Title: Thin-film magnetic head
Inventor: KUHARA MASAKAZU
IPC: G11B5/31
Filed: 1989-10-31
Abstract: PURPOSE:To obtain the thin-film magnetic head which does not require an increase of the number of turns of a coil in spite of the formation of narrower tracks and does not degrade recording and reproducing efficiency by constituting the coil to have the part parallel with the recording width (track width) direction of the front end region of a magnetic pole. CONSTITUTION:The coil 30 is constituted by having the part 30a parallel with the track width direction of the front end region 21 of a magnetic pole. For example, magnetic fluxes intersect perpendicularly with each other in this parallel part 30a in the case of reproduction. The max. output is thus obtd. and the recording and reproducing efficiency is enhanced. The need for increasing the number of turns of the coil 30 is, therefore, substantially eliminated even if the head is formed with the narrower tracks. The need for forming the coil by using the fine patterns of the narrowed pitch between the coils 30 does not arise.
