Title: Zener diode
Inventor: YOSHIDA YUTAKA
IPC: H01L29/866
Filed: 1988-11-14
Abstract: PURPOSE:To obtain a Zener diode having small ageing change of a leakage current by forming a P-N junction between two layers in a Zener junction, and extending connecting terminals for a Zener diode from a semiconductor region and other diode layer. CONSTITUTION:A semiconductor region 5 is of P-type with boron, one diode layer 7 and a contact layer 8 are of P-type with the same boron from the surface as an impurity to be simultaneously diffused in higher surface impurity concentration than the former, the other diode layer 10 is formed of reverse n-type with arsenic or antimony as an impurity to be diffused in larger pattern than that of the layer 7 and higher surface impurity concentration than the former. As a result, the semiconductor surface of the P-type one layer 7 is intruded into the other layer 10 to form a P-n junction between the layers 7 and 10 of Zener junction which effectively protects the Zener junction against the influences of the atmospheric air and the oxide on the semiconductor surface to obtain a high performance Zener diode having no ageing change at the Zener voltage, very small leakage current and high reliability.

Title: Over-load prevention device in power transmitting system for vehicle
Inventor: TAKAHASHI KATSUSHI
IPC: F16H35/10
Filed: 1988-11-16
Abstract: PURPOSE:To prevent an engine and the like from being made to be large in size and to be heavy in weight by providing an over-load prevention means for an end section faced out of the engine at an end shaft in the power transmitting system of a vehicle which transmits engine power to wheels. CONSTITUTION:A torque limiting means (over-load prevention means) 40 is provided for an end section faced out of the transmission case (engine unit) of an output shaft 29. When wheels are subjected to over-load so that the wheels are temporarily suspended, a limiting means 40 makes a cam 45 try to rotate a chain sprocket 41. However, load on the sprocket 41 side is great, the cam section 41a of the sprocket 41 is thereby incompletely engaged with the cam 45, and the cam 45 runs out of the cam section 41a while overcoming the repulsive force of four springs 46... so that the sprocket 41 comes to a stand-still. Then, the cam 45 is rotated together with the output shaft 29, and the rotational driving force of the output shaft 29 is not transmitted to the sprocket 41 via the cam 45. As a result, a driving chain 42 is not subjected to excessive tension, various nonconformities accompanied with over-load are thereby eliminated.

Title: Line speech current control circuit
Inventor: TOMI ATSUSHI
IPC: H04M19/00
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To install automatically a current control resistor in a line without manual operation by connecting a current control resistor with a normally closed relay switch connected in parallel therewith and a current sensing resistor in series in the line and opening the relay switch when the voltage produced across the current sensing resistor is a specified voltage or over. SOLUTION: A relay switch 12 is closed when no current flows to a line 2 and a private branch of exchange is not in operation. When the current flows to the line 2 for the first time, a voltage is produced across a voltage sensing resistor 11. When the voltage reaches a prescribed voltage, that is, the Vbe of a transistor(TR) 13 or over, the TR 13 starts the on-operation, drives and holds a relay coil 22 via other TRs, and the relay switch 12 is opened to insert a current control resistor 4. Thus, the current control resistor 4 is automatically installed without measurement of a current flowing in the line 2 and operation of a manual switch, thereby reducing the current flowing in the line 2 to have a specified value or below.

Abstract: PURPOSE:To eliminate the malfunction of AF control by inhibiting the concurrent operation of one means out of an image detecting means and a centering means when either of them is in operation. CONSTITUTION:A linking control means inhibits an image forming system 4 from being moved by the centering means when a photoelectric transfer means 14 being an image detecting means is in operation, or inhibits the photoelectric transfer means 14 from operating while the image forming system 14 is moved by the centering means. Therefore, the range-finding operation of an AF device is performed unless an image blur preventing device is centering. Thus, the AF device never fails in range finding, and malfunction due to erroneous range finding never occurs.
