Filed: 1983-10-31
Abstract: PURPOSE:To align the axes of cores to each other accurately by making a position adjustment by jogging a microscope and a light source so that the microscope and light source has invariably the same position relation. CONSTITUTION:The light source 11 and microscope 14 are jogged and positioned in an (y) direction for vertical observation so that the light source 11, optical fiber 11, and microscope 14 are arranged vertically in a line.

Title: Optical receiver
Inventor: OIMURA KATSUHIKO
IPC: H04B10/60
Filed: 1984-09-29
Abstract: PURPOSE:To reduce easily and at a low cost an influence of a dark current of a photodetector by selecting a bias current of a reference voltage circuit so as to be smaller than a bias current of an amplifier, to the extent that a variation of a DC output voltage by a temperature variation of the reference voltage circuit becomes the same characteristic as a variation of the DC output voltage of the amplifier by a temperature variation of the dark current of the photodetector. CONSTITUTION:An optical receiver 10 is constituted of a photodetector 13, an amplifier 11 for amplifying an output signal of the photodetector 13, a reference voltage circuit 12 for generating a reference voltage, and also a comparator 14 for comparing an output of the amplifier 11 with the reference voltage from the reference voltage circuit 12. In the optical receiver, when a temperature rises, a bias current of the reference voltage circuit 12 is selected so as to be smaller than a bias current of the amplifier 11. In this way, a degree by which an output voltage of the reference voltage circuit 12 is varied in the direction of negative becomes high, and accordingly, a drop portion of the output voltage by a dark current of the photodetector is compensated by a larger variation portion in the direction of negative.

Abstract: PURPOSE:To accurately compute the remaining capacity of a battery by installing a remaining battery-capacity computation circuit in a battery pack, and installing a display unit which displays the remaining capacity of the battery in an electrically charged type equipment main-body or in the battery pack. CONSTITUTION:When a battery pack 1 is mounted onto a charger to subsequently charge a battery 2, a voltage corresponding to the magnitude of the charge current is generated in a current detection circuit 8, then A/D conversion is given to the generated voltage in a remaining battery-capacity computation circuit 9, the time product of the digital voltage is computed for each specified sampling cycle and these time products are sequentially added together, so that the amount of a charge of current given to the battery 2 is computed. When the battery pack 1 is mounted onto the equipment mainbody to subsequently feed a current to a load by the battery 2, a voltage corresponding to the magnitude of a current discharged from the battery 2 is generated in the current detection circuit 8, then A/D conversion is given to the generated voltage in the remaining battery-capacity computation circuit 9, the time product of the digital voltage is computed for each specified sampling cycle, and these time products are sequentially subtracted respectively from data of the pre-computed current amounts. The remaining batterycapacity computation circuit 9 continues to compute the remaining capacity of the battery 2 until a power supply switch is opened, and then the computation result data is fed into a display unit 10 so as to display the remaining capacity of the battery. The remaining capacity of the battery, can thus be accurately computed.

Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To enable connection to each point of an impurity diffusion layer through a uniform resistance by providing a contact opening part between an impurity diffusion layer and a wiring layer of a relatively high resistance. SOLUTION: A metallic wiring 1 is connected to a tungsten silicide wiring layer by a first contact 104. The tungsten silicide wiring layer is connected to a drain diffusion layer by a second contact 105. The first contact 104 and the second contact 105 are formed alternately and a metallic wiring is connected to a drain diffusion layer 107 through a resistance of a tungsten silicide wiring layer. An excess current is applied to an input/output terminal, and even if an MOSFET switches on by bi-polar operation, it is a tungsten silicide layer of high melting point that is directly connected to the drain diffusion layer 107 and a contact is not fused. Furthermore, since a resistance of a tungsten silicide layer enters the drain diffusion layer 107 from a metallic wiring in series, discharge current flowing during excess voltage application is limited and electrostatic breakdown strength is improved.
