Patent JP-S61145821-A (JP)
Title: Semiconductor super-lattice device
Inventor: MASHITA MASAO
IPC: H01L21/20
Filed: 1984-12-20
Abstract: PURPOSE:To suppress change of electrical characteristic before and after the irradiation of light at a low temperature and allows increase of electron concen tration by setting a mol ratio (x) of aluminum (Al) to 0.2 or less not including 0 and executing the N-type doping only to the Al1-xGaxAs layer. CONSTITUTION:A device is formed by the super lattice having a period with the structure that the N-type doping is carried out to AlxGa1-xAs (x<0.2) 3 which assures activation energy of N-type dopant as small as several meV and activation coefficient of 100% at a room temperature and the doping is not carried out to AlAs 32 having comparatively small activation coefficient. In general, AlxGa1-xAs (x>2) does not allow the electron concentration to exceed a constant value even when a large amount of N-type dopant is doped. For example, when x=0.5, the maximum value is 10<18>cm<-3> or less. Meanwhile, according to this super lattice structure, the electron concentration of 10<18>cm<-3> can be obtained and instability due to a large time constant in change of elec tron concentration by light irradiation at a low temperature can be eliminated (because a mol ratio of Al x>2 is not used).

Title: Method and instrument for measuring convergence and its adjustment supporting device
Inventor: YANO KIYOSHI
IPC: H04N9/28
Filed: 1991-10-16
Abstract: PURPOSE:To make it possible to measure misconvergence, to reduce the price of a device and to shorten a measuring time by executing the color discriminating processing of a measuring pattern picked up by a black-and-white camera and finding out a line center position in each color. CONSTITUTION:A video signal from a cross pattern generating circuit 1 is displayed on a color cathode ray tube 3 as a black-and-white cross pattern 4. An image processing circuit 6 digitizes image information in an one-frame period obtained from the black-and-white camera 5 by 64 gradations and stores the digitized image data in a frame memory 9. A CPU 7 executes convergence measuring processing based upon measuring algorithm using the image data. Other green and blue fluorescent dots are discriminated from positional relation with a specified fed fluorescent dot, the arithmetic processing of the image close to the center is executed in each color and then, the line center dot is found out to of each fluorescent compute the quantity of misconvergence. Since convergence measurement can be attained only by one image fetching the measuring time can be shortened and the price of the device can be reduced.

Title: Side rotor driving mechanism in oil free system vane type fluid machine
Inventor: NAKAMURA MITSUO
IPC: F04C18/344
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To provide an oil free system vane type fluid machine having the constitution that a vane does not slidingly move even at low speed time by synchronizing rotation of a rotor and a side rotor in a vane fluid machine having a structure that this side rotor, the vane and the rotor rotate together by enclosing and constituting the side rotor in a side cover.

Title: High frequency discharge-pumped laser
Inventor: EGAWA AKIRA
IPC: H01S3/0975
Filed: 1986-11-12
Abstract: PURPOSE:To match a high frequency power source with a laser tube through a coaxial cable, by connecting an inductance element in parallel with the high frequency power source side of the coaxial cable in order to decrease an electrostatic capacity component of the coaxial cable and decreasing a value of a capacitance element. CONSTITUTION:In a matching circuit in which a high frequency power source 1 is matched with a laser tube 4, an electrostatic capacity Q2 component of a coaxial cable 3 in connection length l is decreased by the use of a coil 23 in order to decrease an electrostatic capacity Q1 value of a capacitor 21. Because the electrostatic capacity Q2 of the coaxial cable 3 grows larger in accord with an increase in the connection length l of the coaxial cable 3, an inductance value of the coil 23 needs to be increased in accord with the length of the coaxial cable 3. Thus, while an output voltage of a high frequency power source 1 is much raised, an impedance Z0 can be properly matched with an impedance Z and so the output power of the high frequency power source 1 can be effectively supplied to the laser tube 4.

Title: Screw compressor and freezing device
Inventor: OTSUKA KANAME
IPC: F25B49/02
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a screw compressor improved in efficiency in loading with a partial load, and to provide a freezing device showing the effect of an economizer circuit even in a partial load area. SOLUTION: An inverter 22 controls the rotating speed of a motor 27 so as to control the capacity of a screw compressor body 21. Since the screw compressor-? body 21 is not provided with a slide valve, even when loading with a partial load, in the condition that compression chambers C1, C2 are sealed, the coolant is injected to the compression chambers C1, C2 from an economizer passage. Consequently, even if the coolant is injected to the compression chambers C1, C2, capacity of the suction coolant is not reduced. When loading with a partial load, the number of revolution of the motor 27 and the screw rotor 33 are small and cooling effect with the coolant injected from the economizer passage is showed without reducing the capacity of the suction coolant gas to the compression chambers C1, C2, and efficiency when loading with a partial load is improved.

Title: Starter for passenger guard device
Inventor: OGAWA HITOSHI
IPC: B60R21/16
Filed: 1990-10-05
Abstract: PURPOSE:To greatly enhance operating reliability of a device by generating a bit reversing error when a collision decision threshold value is read in from a memory means, and recovering a true collision decision threshold value when the result of a parity check becomes 'no'. CONSTITUTION:A G sensor 2 is connected to CPU 1 via an A/D converter 21 and a switch 3, which is installed at a vehicle front portion and arranged to be closed upon collision, is also connected to CPU 1. At the time of collision, the CPU 1 reads the deceleration of the vehicle from the G sensor 2 via the A/D converter 21 and integrates this speed value. This integrated value is then subjected to low frequency filtering and the CPU 1 reads a collision decision threshold value added with a parity from a mask ROM 4 to perform a parity check, thereby confirming the correctness of this value. In the case of 'no', a true collision decision threshold value is obtained with reference to a correction table. Next, this collision decision threshold value is compared with the above integrated value. When the latter exceeds the former, the collision is detected to output an ignition signal to an ignition circuit 6 so as to develop an air bag.
