Title: Zoom lens
Inventor: INATOME KIYOTAKA
IPC: G02B15/16
Filed: 1981-11-30
Abstract: PURPOSE:To obtain a zoom lens of about F3.5-F4.8 and f=36-102mm. which has a small diameter of the front lens and high performance, by using 4 groups of lenses (positive, negative, negative and positive from the side of a subject), shifting monotonously and independently the 3rd group toward the subject when the 1st and 4th groups are moved in a body toward the subject and giving the numerical definition to the relation of focal distance among these 4 groups. CONSTITUTION:A zoom lens is provided with the 1st positive group G1, the 2nd negative group G2, the 3rd negative group G3 and the 4th positive group G4 successively from the side of a subject. The G1 is linked with the G4 and shifted in a body for variable magnification from a wide angle through a telephoto range, and the shift of an image surface is compensated with a shift of the G3. An excessive telephoto ratio is prevented at the telephoto terminal, and the diameter of the front lens can be reduced since the diaphragm shifts in a body with the G3. In case the focal distances of G1-G4 are set at f1-f4, respectively, the definitions shown by equations (1)-(3) are given to prevent the deterioration of each aberration as well as to attain a compact structure of a zoom lens.

Inventor: ISHIKAWA KATSUHIKO
IPC: F23D11/44
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To decrease preheating time and remarkably reduce offensive odor upon ignition or the generation of white smoke under low room temperature in a liquid fuel combustion device. SOLUTION: A liquid fuel combustion device comprises an exciting coil 17 for applying a magnetic field 17a to and heating a vaporizing part 12 and a burner part 23 for burning fuel gas vaporized in the vaporizing part 12 which is provided in the magnetic field 17a generated in the exciting coil 17. The vaporizing part 12 generates heat by itself so that it can decrease time required for fuel to reach temperature at which it can be vaporized more remarkably than an indirect heating by a heater or the like. At the same time, the burner part 23 provided in the magnetic field 17a generates heat by induced current to raise temperature and obtain optimum ignition temperature. Thus, the burner part is smoothly and rapidly ignited so that the propagation of flame is urged to the entire surface of a flame hole part.  Accordingly, the propagation of the flame is immediately completed so that the exhausted unburnt air-fuel mixture is decreased and offensive odor upon ignition or the generation of white smoke at low room temperature can be remarkably decreased.

Title: Heterojunction bipolar transistor
Inventor: KOBAYASHI SHINJI
IPC: H01L21/331
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To provide compatibility to both high-speed operation and reliability of an HBT. SOLUTION: An emitter layer 3 is constituted of InGaP or multilayer including InGaP. As a material of a base layer 2, InxGa1-xAs which is composed so that its In-mixture rate x on the emitter layer 3 side becomes lowest and the rate gradually increases toward the collector layer 1 side is used. Since this HBT uses InGaP for its emitter, the layer including As is not exposed, leakage of As is prevented and high reliability can be obtained. In addition, use of InxGa1-xAs gradual variation in composition for the base shortens the base travel time, increasing the operating speed of the HBT.

Title: Control circuit of inverter for single and linking operations
Inventor: HATTA YASUNORI
IPC: H02M7/48
Filed: 1990-07-20
Abstract: PURPOSE:To compensate an instantaneous fluctuation of a power system by providing a synchronous correction circuit which detects the amount of fluctuation of in-phase components and quadrature components separately from each other on the basis of an output voltage vector of an inverter and adding them to outputs of a voltage regulator and a phase regulator of a synchronous throw-in control system. CONSTITUTION:A synchronous correction circuit 50 detects an instantaneous fluctuation on the basis of an output voltage vector of an inverter, and therefore in-phase components and quadrature components which are detected represent differences between a speed of change of the instantaneous fluctuation and response speeds of two regulators. Accordingly, these differences are added to outputs of the two regulators and an output voltage of the inverter 1 changes in synchronization with the instantaneous fluctuation of a power system. Accordingly, a stable state of synchronous throw-in can be obtained, while a stable synchronous operation can be executed with the voltage regulator and the phase regulator maintained in a fixed-value control state which is intrinsic for a PI regulator.
