Title: Protective device for thyristor transducer
Inventor: EJIMA KAZUYOSHI
IPC: H02M7/515
Filed: 1978-07-27
Abstract: PURPOSE: To prevent the destruction of thyristor element in overcurrent and overload by combining a time the thyristor is turned off with a time of the rise and fall of current by means of a current transformer provided to the output side of the inverter.  
     CONSTITUTION: When the load varies, AC wave form detected by the current transformer 23 is made greater, the rise and fall time of current become long, and the pulse widths of output signals of the differential rectifier circuits 41 1  to 41 3  in the detecting circuit 24 are made greater. As a result, output signals of the one shot pulse converters 42 1  to 42 6  by a single pulse, which contains both a turn-off time of the thyristor used in the inverter and a delay time, are compared with signals of the NAND circuits 43 1  to 43 6 , overlapped pulses are delivered from the OR circuit 44 to the switching circuit 45. When an output signal P of the circuit 45 is given to the logic circuit, pulses applied to the power rectifier and inverter are locked to prevent the destruction of thyristor.

Title: Small-power data line, and method for connecting devices to one output
Inventor: STEVEN K BANA
IPC: G11C7/10
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the need to drive the whole line for every access, and to reduce the power conditions of a data line, by providing a switch, which accesses respective devices and supplies data to an output, and selectively disconnects segments of the line connected to the devices. SOLUTION: In the line 30, >=1 switches 40 are arranged, and devices, which can disconnect respective electric circuits are built therein. The switches 40 are operated under the control of a switching system 42 to selectively disconnect one segment of a line 30 connected to one of memory blocks 12. Consequently, the need to drive the whole line 30 every time one of memory cells is accessed is eliminated. Consequently, precharge loss is reduced by enabling access to the segments from the switch 40 to an upper line 30 while a precharge state is held, and at the same time the time of access to data along the line 30 is shortened.
Patent JP-H02270524-A (JP)
Title: Mold for plastic lens
Inventor: MARUYAMA TERUNORI
IPC: B29L11/00
Filed: 1989-04-13
Abstract: PURPOSE:To mold a highly accurate plastic lens in a shortened molding cycle by a method wherein the diametral dimensions of the part, which connects to a gate and is on the gate side, of a runner are specified. CONSTITUTION:The gate side part 26 of a runner has a diameter, which is 1.3 times as large as the average thickness between the thickness at the intermediate diameter of a cavity 20 and that at its outer diameter, and a length, which is almost equal to the outer diameter of the cavity 20. The reason why said length is determined is as follows: the amount of resin flowing in the cavity 20 at dwell stage corresponds to the amount developed by the shrinkage of resin in the cavity 20 due to cooling and said amount can be fully replenished by the amount of resin in the gate side part 26 having said length. The volume of the high temperature molten resin, which is filled from a molder to the cavity 20, shrinks by being cooled. The volumetric shrinkage is compensated by the influx of the amount of resin, which is responsible to the volumetric shrinkage of resin, through a gate 27. Since the cooling speed of the resin in the gate side part 26 of the runner is made to be equal to the cooling speed near the gate 27 in the cavity 20, the temperature of inflowing resin can be equal to the temperature of the respective peripheral directional part in the cavity 20, resulting in allowing to shorten molding time.

Title: Production of photosensor
Inventor: KIYOTA KOUHEI
IPC: G03G5/08
Filed: 1979-07-19
Abstract: PURPOSE: To enhance sensitivity for the light of a long wavelength, by vapor- depositing Se onto a conductive material layer at a temperature, where the Se layer is not crystallized, to form an electric charge transfer layer and by subjecting layers to heat treatment at a specific temperature after vapor-depositing an SeTe alloy layer onto the Se layer to form a light carrier generating layer.  
     CONSTITUTION: Se layer 2 is formed on conductive substance 1 at a temperature, where Se is not crystallized, by the vapor deposition method. Next, SeTe alloy layer 3 is vapor-deposited onto layer 2 to form a light carrier generating layer. Next, layers are subjected to heat treatment at a temperature within the range 60W80°C  for approximately 20min to form blocking layer 4 on layer 3, thereby obtaining a photosensor. In the obtained photosensor, leakage of charged electric charge is small, and light-exposure sensitivity is not changed for repeat of printing operations of electrophotography. Consequently, high-quality reproduced pictures can be obtained repeatedly. The photosensor has a high sensitivity for irradiation light L of a long wavelength, for example, semiconductor laser and makes it possible to make the electrophotographing unit small-size.

Title: Input and output controlling system

IPC: G06F13/12
Filed: 1981-06-18
Abstract: PURPOSE:To reduce useless processing of CPU which usually occur when the communication controller is connected to plural input output controller, by giving an autonomous retrial run function of the access to the communication controller and the file memory to the input output controller. CONSTITUTION:When an input output controller 3 receives a transfer signal from central controller 1, a common controlling section 34 makes an access request to a communication controller 5 and starts a timer 35 through a communication controller interface circuit 33. When the circuit 33 receives an answer from the controller 5, the circuit 33 sends a stop signal to the timer 35 and, at the same time, informs the control section 34 of the answer. When the stop signal does not come within a fixed time, the timer 35 gives a time-out signal to a counter 36 and informs the control section 34 of the time-out. When exceeds a fixed value, the counter 36 informs the control section of an overflow. The control section 34 makes a transfer operation against a normal answer and an access retrial run against time-out information and makes an abnormality completion report to the controller 1 against an overflow information. Therefore, useless processings of the controller caused by simultaneous access requests are reduced in number.
