Title: Grater
Inventor: SUMIKAMA TOSHIO
IPC: A47J43/25
Filed: 1991-11-27
Abstract: PURPOSE:To allow grated pieces of material to come down easily through non-blade parts of holes as the material is grated by arranging a part with blades and a non-blade part in each of through holes of a grater. CONSTITUTION:A plurality of through holes 2 are arranged parallel across the width in rows on a base plate 1. The through holes 2 are each provided with blades to form a blade part 2a on one hand and none to form a non-blade part 2b on the other. Even in a grater in which blades are formed on the entire circumference of circular holes 2, the non-blade part 2b can be formed with ease simply by cutting the half circular part thereof off in a half circle containing blades. A radish is grated by the blade parts 2a. With the sliding of the radish, radish pieces left on the base plate 1 and those on the blades of the blade parts 2a drop through the separate non-blade parts 2b following the radish. This eliminates possibility of leaving the radish pieces on the blades thereby achieving higher grating efficiency.

Title: Compound semiconductor wafer
Inventor: TSUCHIYA TADAITSU
IPC: H01L29/812
Filed: 1989-12-04
Abstract: PURPOSE:To provide a high-quality FET with a low drain conductance by doping the interface between a buffer layer and a substrate at a specific concentration to create an acceptor level. CONSTITUTION:A buffer layer 2 of undoped GaAs and an active layer 3 of n<+>-AlAs are formed on a GaAs substrate 1. Drain, source and gate electrodes are formed on the active layer 3 to provide a HEMT(high electron mobility transistor). Impurity is introduced to the interface between the substrate 1 and the buffer layer 2, including a portion within 30Angstrom  from the interface, to provide an acceptor level. The doping concentration is more than 10<10>cm<-2>, preferably more than 10<11>cm<-2>. The doping of impurity for the acceptor level improves the pinch-off characteristic of a FET and decreases the leakage current flowing to the substrate 1 and the buffer layer 2. This reduces the drain conductance, thereby reducing the manufacturing cost of a FET.

Title: Object pinch sensing device of elevator car door
Inventor: KATO ISAMU
IPC: B66B13/26
Filed: 1994-12-19
Abstract: PURPOSE: To provide an object pinch sensing device for a cage door of elevator, whereby the elevator is prevented from running while the cage doors are pinching a thin object of such a thickness as not sensible by a safety shoe. CONSTITUTION: Cage doors are shut and an energizing coil 19 for protrusion is energized, and thereby a suction plate 12 is sucked. This causes rotation of a working arm 13 round its axis to protrude from a lefthand car door 1A while an object pinch sensing plate 11 is lifted. At this time, an interlocking arm 14 also rotates round the fixed shaft, as flucrum while the object pinch sensing plate is hung down. In case the plate 11 protrudes in the door shutting direction and no foreign object exists between the cage doors, a movable contact 23 is guided by a guide plate 22 and contacts with a stationary contact 24 to generate electric continuity, and a signal is emitted from the output terminal 25.  In case there is any foreign matter between the doors, the movable contact 23 does not contact with the stationary contact 24, and no output signal emission takes place from the output terminal 25 within the set period of time, and the cage doors are opened again.

Title: Magnetic disk device
Inventor: UENO KAZUTAKA
IPC: G11B5/00
Filed: 1987-12-11
Abstract: PURPOSE:To detect a foreign matter on a magnetic disk and to prevent a head crash by providing a light-emitting part which emits light beams and a light- receiving part which receives the light beams on the outer peripheral part of the magnetic disk and a reflection part which reflects the light beams on the central axis part of the magnetic disk. CONSTITUTION:The reflection part 3 of a rotation axis reflects the light beams from the light-emitting part 1 and the light-receiving part 2 receives them. The photoelectric converter 7a of a foreign matter detection device 7 transforms the laser beams emitted in the light-emitting part 1 and the light beams which the light-receiving part 2 has received into currents corresponding to the strength of the light beams. Next, a rotation axis controller 7b compares two kinds of currents and judges to be no foreign matter when they have the same current values. Since the light beams emitted in the light-emitting part 1 is blocked by the foreign matter when the foreign matter 5 exists, two kinds of current values differ and the foreign matter is judged to be existed, whereby a magnetic disk rotation axis driving device 8 stops the rotation of the magnetic disk. Thus, the disk crash can previously be prevented.
