Inventor: SAGIYAMA MASARU
IPC: C25D5/10
Filed: 1991-01-14
Abstract: PURPOSE:To produce the double-layered iron-zinc alloy plated steel sheet having excellent electrodeposition coating suitability which does not generate bubble-like defects in a coated film and does not generate pinholes therein even when the steel sheet is subjected to severe forming. CONSTITUTION:The galvannealed iron-zinc alloy plating layer is formed as a lower layer on the surface of the steel sheet and thereafter, many fine cracks are formed by mechanical means on this lower plating layer. This steel sheet is then subjected to an iron-zinc alloy plating treatment, by which the iron-zinc alloy electroplating layer as the upper layer is formed on the lower plating layer. Consequently, the concn. of the stresses from the upper layer is suppressed by the many fine cracks formed in the lower plating layer at the time of forming and the bubble-like defects arising in the coated film are prevented.

Title: Distance detector
Inventor: NAGAOKA SHINJI
IPC: G01C3/06
Filed: 1984-01-30
Abstract: PURPOSE:To make it possible to detect the distance highly accurately with a good S/N ratio, by inputting only the difference signal between two sensor outputs, and detecting the fact that the output of an amplifier circuit becomes zero, by using the scale of the circuit equivalent to a one-sensor type device. CONSTITUTION:Light from a light emitting element 1 is projected on an object 3 through a light projecting lens 2. The reflected light is detected by a sensor 5 having two divided parts, which comprises light receiving elements 5a and 5b such as two silicon photodiodes through a light receiving lens 4. At first, before the scanning is started, the amount of light inputted to the element 5b is larger than that inputted to 5a. Therefore, the output current of 5b is large. The positive pulse signal is inputted to the input terminal of a first stage amplifier 11 through a capacitor 12. With the scanning of the sensor having the two divided parts, the reflected light slowly moved over 5a from the element 5b. The output current of 5a becomes larger than the output current of the element 5b. When the outputs of the elements 5a and 5b become equal, the input to the amplifier becomes zero. This fact is detected by a voltage comparator 22. The amount of scanning at this time corresponds to the distance to the object.

Title: Holder for internal container of gyro device
Inventor: MINOHARA KIYOMI
IPC: G01C19/24
Filed: 1980-02-08
Abstract: PURPOSE:To float an internal container without impeding north indicating motion by filling the gap between an external container and the internal container with a magnetic liquid and by arranging magnets at adequate circumferential positions of the external container. CONSTITUTION:The gap between spherical external container 1 and spherical internal container 3 which has an incorporated top rotating at a high speed is filled with a magnetic liquid and at adequate circumferential positions of external container 1, permanent magnets (or electromagnets) 5 and 6 are arranged. The directions connecting the N poles and S poles of magnets 5 and 6 together are made to agree with the tangent directions of the sphere so as to prevent the magnetic fields from operating upon the inside of the internal container as much as possible. As internal sphere 3 gets close to external sphere 1, internal sphere 3 is held nearly in the center of external sphere 1 by being applied with the repulsive force of the electromagnetic liquid of high density near the magnets. Thus, internal sphere 3 can be floated without impeding the north indicating motion.

The comparing unit 20 compares the first interval and the second interval, and when the difference between time intervals is smaller than a specified minimum value, it is shown on a display means 24 as the capture of an atrium exists.

Title: Origin position setting method for seat position of motor-driven seat
Inventor: HIDAKA MASURO
IPC: B60N2/06
Filed: 1991-02-06
Abstract: PURPOSE:To make the capacity of a volatile memory circuit so small as to store a rotation detection signal only by taking the position of a seat as the first home position when a current is first supplied to a circuit, and moving the home position to the last end every time the position of the seat is moved backward from the home position. CONSTITUTION:When a current is first supplied to a control means 9, a preset memory 7 and a current position memory are set to the initial state, and the position of a seat 2 is taken as the first home position. When the seat is moved by a manual operation means 6, a signal of a rotation detection means 8 of a seat driving motor is added to store the position data of the seat 2 by a memory 15. When the seat 2 is further moved to the home position, a signal of the rotation detection means 8 is subtracted to store the position data of the seat 2 by the memory 15. The position where the movement of the seat 2 stops is taken as a new home position to change the data value of the preset memory 7, and the position data of the memory 15 is again initialized.

Title: Method and device for optical inspection of bottle or the like
Inventor: KURAHASHI MICHIHITO
IPC: G01N21/90
Filed: 1987-01-26
Abstract: PURPOSE:To preclude misdetection, overlooking, etc., by comparing comparatively plural video signals obtained by scanning the outer surface of an empty bottle at plural scanning positions in opposition relation and deciding whether or not the empty bottle is normal/defective according to the obtained comparison data. CONSTITUTION:Inspection areas at the respective scanning positions are four areas A, B, C, and D of a bottle mouth part. In this case, misdetection caused by the curved surface shape of the bottle mouth part is precluded and the accuracy of the normal/defective decision making of the bottle 1 to be inspected is improved. The shape of the mouth part 3 of the empty bottle 1 is normally constant in its peripheral direction and the peaks of video signals of the respective scanning positions appear at nearly the same signal position. When the empty bottle 1 is normal, the values of comparison data at the respective scanning positions which are obtained by comparing the peak values are considerably small. If the empty bottle has a defect or stain, etc., inspection light is reflected irregularly to generate an abrupt raise or fall in brightness level. Consequently, it is accurately decided whether the empty bottle is normal or defective.
