Title: Wavelength selection type optical demultiplexing and distributing device
Inventor: IMOTO KATSUYUKI
IPC: G02B6/28
Filed: 1984-01-25
Abstract: PURPOSE:To obtain a device which has an optical demultiplexing and an optical distributing function integrally by heating and drawing circumferences of tips of an input optical fiber and a demultiplexing output fiber which are arranged in parallel, and connecting an optical distributor to the slanting cut and polished surface. CONSTITUTION:The light signal of an optical fiber transmission line 1A is transmitted in the input optical fiber 11 to reach an interference film filter 13. The filter 13 allows only a light signal with wavelength lambda1 to pass and reflects remaining light signals with lambda2-lambdan. The transmitted light propagates as shown by an arrow 34 and is demultiplexed equally to respective distributing output optical fibers of the distributor 14. Reflected light is coupled with a fiber 12 by a taper part 15 and transmitted to an optical fiber transmission part 1B. The taper part 15 is formed thinly by heating and drawing the fibers 11 and 12 near their tips. The tip of the taper part 15 is cut slantingly at a desired angle theta and polished, and the filter 13 is vapor-deposited on the polished surface. Thus, the device which has the optical demultiplexing and distributing functions integrally is obtained.

Title: Control circuit for auxiliary power source
Inventor: MOCHIZUKI OONORI
IPC: H02J9/06
Filed: 1978-01-30
Abstract: PURPOSE: To accomplish automatic control of power supply in case of power failure by means of a second switch interlocked with the main switch of the equipment body employed for the on/off operation between the main power and the control circuit for the first switch designed to turn the auxiliary power source on or off the main power source depending on the voltage changes of the main power source.  
     CONSTITUTION: A drop in the voltage of the DC main power source due to power failure or the like is detected with a detection circuit 8 while the main switch of the equipment body is closed. Based on the output and a reference potential of a main power source 2 through a second switch remaining closed, a opening/closing control circuit 9 outputs a closing signal to close a first switch 11. Thus power is fed from an auxiliary power source. As the voltage of the main power source 2 rturns to normal, a diode is biased in the reverse direction and a zero voltage is detected to open the switch 11. Thus, the power feeding is halted. When the main switch is opened while the switch 11 is closed, the switch 3 is opened. Due to lack of the reference potential, the action of the opening/closing control circuit 9 is halted leading the switch 11 to be opened.

Abstract: PURPOSE: To make a sharp transition to a backscattering electron level by performing etching along the patterns of an isolation oxide and an alignment mark and making a trench of mark surround by the oxide in a wafer. CONSTITUTION: An SiO2 layer 20 and an Si3 N4 layer 22 are formed on a silicon substrate 10 and a laminate is exposed and etched along the ROX patterns of an isolation oxide and an alignment mark. Consequently, a pattern of a mark region 30 surrounded by an ROX 24 is formed on a wafer 10. Subsequently, the wafer 10 is coated with a resist except the region 30 and etched down to a specified depth using the ROX 24 as a mask thus forming a trench mark surrounded by the ROX 24. According to the method, an irregular structure being utilized for generating backscattering electrons causing inter-edge waveform transition is obtained.

Filed: 1989-01-18
Abstract: PURPOSE:To execute an accurate transport of recording paper by providing a capstan roller for transporting recording paper at the downstream side of a platen roller and driving the platen roller while being driven by the capstan roller. CONSTITUTION:A platen roller 2 is driven by rotation of a DC motor by turning an electromagnetic clutch connected to the platen roller 2, and at the same time, a capstan roller 3 is driven by rotation of a stepping motor. If recording paper 36 is transported in a forward direction, the peripheral rotation of the platen roller 2 is set so that it is delayed without the recording paper 36 compared to that of the capstan roller 3. However, if the recording paper 36 is inserted, the platen roller 2 is dragged by the capstan roller 3 to reach the same peripheral speed as that of the capstan roller 3.

Title: Self-shrinkable wedge fixing rail gun and suppressing method of interrail rebounding force
Inventor: NAKAMURA SATOSHI
IPC: F41B6/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a rail gun to be excellent in assembly workability and maintainability. SOLUTION: Since, though an interrail rebounding force f1 intends to spread a pair of wedge members 8R and 8L to the outside, wedge surfaces 8a and 8b make contact with wedge surfaces 4a and 4b, a part of a force to spread a pair of the wedge members 8R and 8L to the outside is converted into a force f2 to press a pair of fixing steels 4T and 4B against each other for offsetting with each other. Since a need to use a number of bolts and effect fastening by a uniform force is eliminated, workability of assembly of a rail gun 100 is extremely improved. Further, since a need to effect re-fastening of a number of the bolts is also eliminated, maintainability is also remarkably improved.

Title: Light emitting element driver
Inventor: NAKAHARA TAKASHI
IPC: H01S5/042
Filed: 1988-01-22
Abstract: PURPOSE:To facilitate the avoiding of abnormal light emission of a light emitting element with a high accuracy at a low circuit cost and, further, suppress the deterioration of the performance of the light emitting device by a method wherein a current limiting means which limits a driving current applied to a switching means from a second electric source until a potential applied to a luminous power control means from a first electric source gets stabilized. CONSTITUTION:A current limiting means is composed of, for instance, a switching transistor TR2, resistors R10 and R11 and so forth. If a voltage V1 applied to the base of the switching transistor TR2 through the resistor R10 does not exceed a resultant potential 3, 4V of voltages VBE2 and VBE3 and a laser operation voltage VLD, the switching transistor TR2 is not turned ON. Therefore, even if the potential of the voltage V1 fluctuates, as far as it does not exceed the resultant potential 3, 4V, the light emitting operation of a semiconductor laser LD is restricted and, when the voltage V1 exceeds the resultant potential 3, 4V, a microcomputer 1 is already in a normal operation so that the possibility of abnormal light emission can be avoided.

Title: Manufacturing device for tape electrical wire
Inventor: KASAI TOSHIAKI

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing device for a tape electrical wire, which is high in laminating strength, is table in properties, concurrently can enhance a manufacturing efficiency by increasing the rotation speed of each roll, and also can avoid degrading the life of each roll. SOLUTION: A tape electrical wire and a reinforcing plate are held with pressure by means of metallic rolls 40a and 40b so as to be mutually welded. In this case, a gap between the rolls 40a and 40b is determined in advance in response to the rotation angle of the roll 40b, and concerning date is stored in a memory 64. In a laminating process for the reinforcing plate, the rotation angle of the roll is detected by a rotary encoder 60, the gap between the rolls is thereby determined by a controller 65 based on the detected value of the rotation angle and data from the memory 64, and when the gap between the rolls is found to have been larger than a reference value, a signal permitting the roll 40a to be moved to the direction that the gap is made small is outputted to a pulse driver 62.  On the contrary, when the gap between the rolls is found to have been smaller than a reference value, a signal permitting the roll 40a to be moved to the direction that the gap is made larger is outputted to the pulse driver 62. By this constitution, the gap between the rolls can thereby be kept constant.
