Title: Incandescent lamp
Inventor: YOSHIIKE RYOJI
IPC: H01K1/26
Filed: 1990-02-26
Abstract: PURPOSE:To improve luminous efficiency and miniaturize an incandescent lamp by covering the interior of a glass bulb with a selective translucent reflector permeating the visible light from a filament and reflecting the infrared light, and fixing part of the translucent reflector on one of a pair of lead wires. CONSTITUTION:A cylindrical selective translucent reflector 17 is coaxially coupled with a slack on the outer periphery of a filament 13, the center section of a fitting plate 18 is inserted and fixed to one lead piece 14a, and the selective translucent reflector 17 is fixed to the lead piece 14a. A selective translucent reflecting film 17b permeates the visible light among the light emitted from the filament 13 and reflects the infrared light to return it again to the filament 13, thus the filament 13 is heated to increase its temperature, and luminous efficiency is improved. Heat conduction is reduced when a bulb 12 is heated, thus the bulb 12 is not required to be made large-sized. Luminous efficiency is improve, and the bulb 12 can be miniaturized.

IPC: H04B10/548
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To enable one photoelectric converter to receive signals from many terminal stations without deteriorating the quality of the signals. SOLUTION: Optical communication equipment modulates signals transmitted from terminal stations 11-1n into subcarrier signals having different frequencies and converts the subcarrier signals into intensity-modulated light by means of photoelectric converters 3 having different light emitting wavelengths and the intensity-modulated signals are received by means of the photoelectric converter 8 of a center station 7 through an optical fiber. The number (m) of simultaneously receivable waves of the converter 8 is smaller than the number (n) the intensity-modulated light rays.  Each terminal station 1 has a pulsed light emitting function which emits intensity- modulated pulsed light modulated by a subcarrier signal for time division multiplexing having a frequency different from that of the above subcarrier signals by modulating the transmitted signals into the subcarrier signal for time division multiplexing in addition to a function which continuously emits the intensity-modulated light of the transmitted signals. The emission of the pulsed light is performed in accordance with the time slot of a time division multiplex system at every subcarrier signal for time division multiplexing and the photoelectric converter 8 always simultaneously receives intensity-modulated light equal to or less than the number (m) of simultaneously receivable waves.

Filed: 1990-02-23
Abstract: PURPOSE:To enable fine-patterning so that print resolution is improved by delaying the energization and heat generation of the second row of thermal resistance elements using a drive circuit by time equal to a distance over which the second row of thermal resistance elements are displaced from the first row of thermal resistance elements. CONSTITUTION:A wiring electrode 11 is formed on an insulating substrate, and thermal resistors 12 are connected to the wiring electrode 11. In this case, the first row of thermal resistance elements 14 of the thermal resistor 12 are aligned in a straight line of a main scan direction, and the second row of thermal resistance elements 15 are arranged between the first rows of thermal resistance elements 14. In addition, the second row of thermal resistance elements 14 are arranged in a straight line of a main scan direction X in such a way the they are displayed by an integral multiple of a feed pitch of a subscan direction Y. Thus wiring electrodes 11 are patterned as described above. Subsequently, thermal resistors 12 are aligned in a non-linear pattern like the wiring electrodes 11. Therefore, if the film thickness of the wiring electrode 11 connected to the thermal resistor 12 is not large, the width of the line becomes large and the space becomes small. For this reason, the size of thermal dots becomes large and the interval between dots becomes narrow. After all, a high density pattern is realized.

Abstract: PURPOSE: To reduce the consumption of motive power in a device for operating a cargo box lifting/lowering valve and a motive power pick-off unit with a single operating lever, by switching off the motive power pick-off unit in a neutral position on the way of shifting of the valve.  
     CONSTITUTION: A valve 5 is shifted to a neutral position through a wire 9, a bell crank 8, etc. and a rocker member 14 is swung to a chain line position when an operating lever 7 is displaced from a position (a) to another (b) as the valve 5 for controlling a hydraulic cylinder 6 for moving up a cargo box up and down is in a lower position and a motive power pick-off unit 1 is disconnected as shown in Fig. At that time, a shifter 2 is not moved because a link member 17 coupled to the shifter is bendable. When the operating lever 7 is displaced to another position (c), the valve 5 is shifted to an upper position and the shifter 2 is operated through the link member 17 whose bending motion is restricted by a stopper 20. At that time, the motive power pick-off unit 1 is connected.

Abstract: PURPOSE:To enable to read in the required information exactly at a given time from the device to be controlled, by making the CPU read in the operating status information from the reception device to be controlled, through the display of the time measuring means provided with CPU for a given time elapsed. CONSTITUTION:After CPU stores the diagnostic data to the main memory unit MM, the start instruction is transmitted to the diagnosed device to be controlled U2 at time point t2. The device U2 reads out the diagnostic data from the unit MM via the path 3 at the period absent in real time information processing instruction, operates as self-automatically, and stores the operating status information Si to the register REG. The information Si changes to S1, S2... and becomes Sn at the time point t2n and this is stored until the time point t2(n+1). CPU starts the diagnostic timer TM at the time point t2 and when the timer displays the elapse of time T0 while the device U2 stores the information Sn, interruption is made and the information Sn is read in from the register REG. Thus, CPU can read in the required information Sn surely without impairing the real time information processing.
