Title: Antenna control circuit
Inventor: ICHIYOSHI OSAMU
IPC: G05D3/00
Filed: 1990-03-16
Abstract: PURPOSE:To surely control the direction of an antenna at a high speed even when the band width of an AGC loop is narrow by calculating the means value and variance value of received IF signal levels and comparing them with values which are set previously. CONSTITUTION:A signal from a communication satellite, etc., which is received through a tracking type directional antenna 1 is converted by a converter 2 into an IF signal and an AGC amplifier 3 attracts and outputs long-time means level variation. Then a direction controller 12 generates an antenna tracking signal with the mean value of the output signal of a level detector 4, so variation in the level of the output can accurately be detected. The output signal, however, is controlled so that the long-time mean level variation is made nearly constant regardless of the direction of the antenna 1, so the arithmetic result from the mean value and variance value of the output signal of the detector 4 is compared with the preset values to judge whether or not the direction of the antenna 1 is proper. Consequently, the best reception direction of the antenna 1 can surely be determined at a high speed.

Title: Label sticking method for film unit with lens
Inventor: WATANABE FUMIO
IPC: G03C3/00
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a label sticking method for a film unit, capable of enhancing impact resistance and quality by closely sticking front and rear covers to a main body base part. SOLUTION: The rear cover 10 is supported by a rear cover supporting head 92, so that when the front cover 9 is pressed by a front cover pressing head 90, the main body base part is held between the front and rear covers 9 and 10. In a state where this pressed state is still kept, a label 4 is wound/ stuck over both of the front and rear covers 9 and 10. Since the label 4 is stuck in such a manner that the main body base part is held between the front and rear covers 9 and 10, the backlashes of the front and rear covers 9 and 10 are prevented to increase the degree of the impact resistance.

Title: Electrodeposition tool
Inventor: YANO HIDEO
IPC: B24D3/00
Filed: 1995-03-01
Abstract: PURPOSE: To achieve elimination of choking at the time of cutting work, reduction of cutting resistance, elongation of life, etc., in an electrodeposition tool comprising super-abrasive grain fixed on an upper surface of a base metal by electrodeposition by applying plating of gold or gold alloy to the surface of the layer on which the super-abrasive grain is fixed. CONSTITUTION: An electrodeposition tool comprises super-abrasive grain 2 fixed on an upper surface of a base metal 1 by electrodeposition, that is electroplating, through metal 3 such as nickel. In this case, on the surface of the metal 3, in addition, plating of gold or gold alloy is applied to form a layer 4 of gold or gold alloy. That is, the layer 4 of gold or gold alloy is formed only on the surface of the metal 3 which needs to be protected from attachment of cutting chip in the electrodeposition tool. In this electrodeposition tool, therefore, adhesion to the cutting chip is small at this surface, so cutting performance becomes favorable, with life elongated, and the tool can be used for a long period. Because of this small adhesion force to the glass cutting chip, this can be applied to a centering wheel of a glass lens, for example.

Abstract: PURPOSE:To prevent concentration of an electric current only in the vicinity of a gate arc electrode in a thyristor at arcing time by specifying the width of low net- like impurity layer operating as a current control terminal of the thyristor to special value. CONSTITUTION:Net-like pattern P<++> type buried layers 2, 31-33, 41-44 are radially formed at the P2 layer of a thyristor having P1 layer, N1 layer, P2 layer and N2 layer excluding the central portion. In this case, the width t in a direction requiring the expansion of conducting direction is set less than 300mu, and the width w in a direction considering with no expansion of the conducting region is equal to the width t or larger. When the width t exceeds 300mu, the exapnsion of the arcing current in the direction as designated by an arrow 11 is obstructed to increase the voltage drop thereat and to lower the turn-off enable current. That is, the conducting area is not almost expanded in a direction as designated by an arrow 12 having, for example a width of 400mu at the low resistance buried layer, but less than 300mu, the conducting area is easily increased in width in a direction as designated by an arrow 11.

Filed: 1978-06-06
Abstract: PURPOSE: To reduce normal loss by employing two reactors corresponding with secondary and thertiary loading determined on the bais of formula analysis in place  of a resistor.  
     CONSTITUTION: Additional reactors 15, 16 having different reactances are connected in parallel with each of low-voltage relay, where the reactances are set in accordance with the reactances of two low-voltage relays 13 connected to the secondary of grounded metering transformer 1 and relat load of low power factor connected at the tertiary of transformer. One low-voltage relay can be functioned during the phase missing of any phase at the primary of transformer 1. In other word during primary phase-missing, any one of two line voltages out of three can be lowered below the setting level. Consequently the blown-off of primary fuse can be detected separately from the bus voltage drop where both line voltage drop. Furthermore the heat generation and power loss can be eliminated when compared with conventional detection of the blown-off of primary fuse where a resistor is employed.
