Title: Brushless dc motor
Inventor: GOTOU MAKOTO
IPC: H02P6/28
Filed: 1982-06-10
Abstract: PURPOSE:To stably and effectively drive in full-wave a brushless DC motor and to prevent the oversaturation of a drive transistor by controlling the energizing time operating state of the second drive transistor group so that the operating voltage at the energizing time of the first drive transistor group becomes the prescribed value. CONSTITUTION:The first feedback loop (current feedback loop) is composed of a current controller 21, the first selector 22, the first drive transistors 5-7, a coil current detecting resistor 26, and a resistor 27, and is operated so that a coil current detection signal Va is equalized to a command signal V1. The second feedback loop is composed of an operation detector 41, the second selector 61, and the second drive transistors 8-10, and the energizing time operating voltage detection signal V4 of the first drive transistor is equalized to the reference voltage V2. The output signal 71 of the speed detector 70 at the motor starting time is small, but the coil supply current Ia is corrected in response to the command signal V1 in response to the signal 71 and the output current i7 of the detector 41, thereby preventing the oversaturation of the first drive transistors 5-7.

IPC: F15B1/02
Filed: 1984-05-21
Abstract: PURPOSE:To improve the response of cylinder at start by providing an auxiliary accumulation chamber filled with gas between an accumulator and cylinder and opening a valve for communicating between the auxiliary accumulation chamber and conduit tube simultaneously with opening of pressure oil valve.

Title: Method for inspecting semiconductor device
Inventor: NISHIDA SHIGERU
IPC: H01L21/66
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To detect defects of wiring members with a high positional resolving power. SOLUTION: A laser beam output from a laser light source 1 is changed to a pulse form by a pulse signal from a pulse drive control part 11. At this time, a pulse width of the laser beam output is made equal to or shorter than a thermal diffusion time constant of a wiring member of a sample 5. A pulse cycle is set to be longer than the thermal diffusion time constant so that a laser irradiation part when the laser beam is turned on immediately before turned off can obtain a sufficient cooling time while the laser beam is off. A sampling signal is sent to a sampling and hold circuit 14 synchronously with the pulse signal from the pulse drive control part 11. A current signal from a current-detecting part 7 is sampled and held with a timing based on the sampling signal.  The sampled current signal is converted to a digital signal by an AD converter 8 and sent to an image-processing part 9.

Title: Exhaust gas decomposing device
Inventor: TAMAURA YUTAKA
IPC: C01B32/50
Filed: 1990-04-16
Abstract: PURPOSE:To efficiently decompose carbon dioxide by providing a means for detecting the activated state of a decomposer, activating the decomposer in a low-temp. chamber and bringing the activate decomposer into contact with a gas contg. carbon dioxide. CONSTITUTION:A decomposer 1 consisting of an iron oxide such as magnetite is placed in a chamber 2, the chamber 2 is held at 200-350 deg.C, and the magnetite is transformed into an oxygen-deficient state. A gas contg. carbon dioxide is then introduced into the chamber 2, the carbon dioxide is catalyzed by the oxygen-deficient magnetite to form magnetite and carbon, and the carbon is successively deposited on the surface of the magnetite 1. Since the carbon dioxide decomposing function is deteriorated when a large amt. of carbon is deposited, the activated state of the decomposer 1 is detected by a detection means, and a signal is raised. Thus, carbon dioxide is efficiency decomposed in this way to prevent the warning of the earth's atmosphere.

Filed: 1981-06-29
Abstract: PURPOSE:To operate correctly left parts of a system, by reflecting the state of dissidence to the system when contents of configuration controlling information, which respective devices have, do not coincide among >=2 devices. CONSTITUTION:Devices A and B have configuration controlling registers CFRa and CFRb where configuration controlling information indicating systems, to which devices A and B belong, are stored. Judging circuits Ja and Jb discriminate systems, to which devices A and B belong, on the basis of configuration information in registers CFRa and CFRb and discriminate whether powers of devices B and A of each other are turned on or not on the basis of power-on state indicating signals.

Title: Telephone set
Inventor: HORIBE KOICHI
IPC: H04M1/673
Filed: 1988-04-26
Abstract: PURPOSE:To prevent a wrong dialing to a specific telephone number due to a mischief of a child or the like by devising that the dialing is regulated to a predetermined registered telephone number. CONSTITUTION:A registration button 2 is depressed, a dial number subjected to dial regulation is inputted from a dial 1, stored in a dial storage circuit 4 to turn on a dial regulation button 6. After off-hook, when a dial number subject to dial regulation is inputted by using the dial 1, the dial number is stored once in a dial storage circuit 3 and compared with a dial regulation number registered in advance by a discrimination circuit 5. When the result of comparison shows disabled dialing, a logical '1' is outputted to a logic gate 8. On the other hand, when the dial regulation button 6 turned on, a logical '1' is outputted to the logic gate 8 from the button 6. Thus, the logic gate 8 NANDs the both outputs and since a logic '0' is sent to a dialing circuit 7, the dialing circuit 7 sends no dial number to a line 9. Thus, the dialing is regulated.

Title: Electronic instrument panel
Inventor: KATOUGI KOUZOU
IPC: G12B11/00
Filed: 1984-05-22
Abstract: PURPOSE:To obtain excellent visual recognition by the optimum contrast display, by automatically changing the luminance of the display part of an instrument panel in correspondence with the brightness of the outside of a vehicle cabin. CONSTITUTION:An oscillated output A of an oscillator 4 has a wavelength shown by (a) in the Figure since ON-duty represents a specified rectangular wave. As a result, an output voltage B of a DC-AC converter 3 has positive and negative waves shown in (b). The output voltage B of the converter 3 is supplied to a fluorescent lamp 2. Therefore, the fluorescent lamp 2 emits light at every pulse of the voltage B, i.e., at every edge part of the rectangular-wave output A. The width of the pulse of the voltage B has a constant value determined by circuit constants. The amount of light emission of the fluorescent lamp 2 at every pulse of the voltage B becomes constant. The amount of light emission of the fluorescent lamp 2 per unit time is proportional to the light- emitting frequency per unit time, i.e., the oscillating frequency of the oscillator 4. Meanwhile, the oscillating frequency is changed by the amount of incident light to a photoelectric conversion element 5, i.e., brightness of the outside of the cabin. Therefore the luminance of a display panel 1 is automatically changed in response to the brightness of the outside of the cabin, and the display at the optimum contrast can be always performed.
