Title: Connecting method for optical fiber
Inventor: KIYONO MINORU
IPC: G02B6/30
Filed: 1986-05-19
Abstract: PURPOSE:To shorten the time required for connection/separation of an optical fiber and an optical device, by interposing a connecting unit between the optical device and the optical fiber, and making the connecting unit which has connected the optical fiber adhere closely to the optical device. CONSTITUTION:When propagation constants of light beams of two pieces of single mode optical waveguides, for instance, an optical waveguide 12 and an optical waveguide 42 are equal or extremely similar, the light beam can be propagated from one optical waveguide to the other optical waveguide by making the side face adhere closely. That is, by interposing a connecting unit 4 between an optical device 1 and an optical fiber 2, and connecting the optical waveguide 12 and the optical fiber 2 through the optical waveguide 42, the optical fiber 2 can be connected without polishing an optical fiber joint surface of the optical device 1. Also, the optical waveguide 12 and the optical fiber 2 can be easily connected and separated and for instance, the time required for evaluating a characteristic of the optical device 1, etc. can be shortened.

Title: External component for watch and its manufacture method
Inventor: WAKABAYASHI YUTAKA
IPC: G04B37/22
Filed: 1994-05-27
Abstract: PURPOSE:To contrive high hardenability and improvement of mirror reflection in a titanium-made watch. CONSTITUTION:In a watch high hardenability and improvement of a mirror is contrived by using material which contains iron of 0.5%wt or more in titanium. Furthermore, mirror face finish and surface coating treatment can be made easy by making an average crystal grain diameter 40mum or less. The mirror reflection can be improved by using titanium alloy wherein iron is contained in the watch and contriving the high hardenability and the fineness of the crystal grain diameter. Furthermore, since the watch is made of titanium and iron alloy, skin allergy can be prevented.

Title: Centrifugal impeller
Inventor: NISHIDA HIDEO
IPC: F04D29/28
Filed: 1977-09-28
Abstract: PURPOSE: To improve the efficiency of a centrifugal impeller, by extending the center and side plates on a disc outside the outer diameter of vanes and fitting radial ribs to the extended center and side plates for giving kinetic energy to the boundary layer.  
     CONSTITUTION: The fluid flow is strained to the circumferential and width direction at the vane outlet 4a of an impeller 1, but the circumferantial strain disappears due to the mingling immediate downstream the vane outlet 4a and the circumferential flow is evenly distributed at the impeller outlet 1a. As for the width direction, since the kinetic energy is given by means of ribs 10 to the fluid with low flow rate on the side of side plate 3 and to the fluid in the boundary layer on the side of center plate 2, the flow is also evenly distributed being agitated. Consequently the fluid flow at the impeller outlet 1a ia quite even. Since the flow is even at the outlet of vaned diffuser 7, the flow angle concides with the vane angle along entire length of the width direction, thus almost eliminating the incident loss in terms of the theoretical air flow. This means an improvement in the efficiency

Title: Communication control system between processors
Inventor: TOMINAGA YOSHINOBU
IPC: G06F13/38
Filed: 1984-06-06
Abstract: PURPOSE:To attain direct access to main control processor for the communication area of the memory of a sub ordinate control processor by sending a request for communication from the main control processor and placing the subordinate control processor in a termporary stop state. CONSTITUTION:The main control processor MPU sends communication request information to the subordinate control processor SPU1. The subrodinate control processor SPU1 sends communication ready information to an information line m1 and holds itself in a temporary suspending stop state. The communication ready information of the information line m1 opens a bus gate BG1 corresponding to the subordinate control processor SPU1. Consequently, the main control processor MPU attains direct access to the memory M1 of the subordinate control processor SPU1. When the communication ready information of the information line m1 is ceased, the bus gate BG1 is closed and the communication ready information of the information line l1 is also ceased. Thus, communication control over all subordinate control processors SPU1-SPUn is performed.

Title: Semiconductor integrated circuit device
Inventor: NAKAO HIROOMI
IPC: H03K19/00
Filed: 1986-05-19
Abstract: PURPOSE:To speed up a circuit test by comparing an expected value preset in a storage element with an output from a logic circuit in the titled circuit and giving the result to a fault detection terminal. CONSTITUTION:A pattern is set to each shift register latch SRL 3 through a shift bus SP sequentially from a shift input terminal SIO at the test. An expected output pattern set to the SRL 3 is an input pattern to a logic circuit to the input of the SRL 3. In setting the expected output pattern to the SRL3, the output through the circuit 2 is fetched in the SRL 3 of the output of the circuit 2. When the data input signal differs from the expected value, that is, a fault exists, a fault signal level is 1 in the SRL 3 at the output side to turn on a fault detection switch 4. Even when even one switch 4 is turned on, a signal appearing at a fault detection terminal FOO goes to 1 and the fault is detected. Since the result is given immediately to a terminal FOO, the test time is reduced.

Abstract: PURPOSE:To increase driving torque and to attain a favorable accelerating condition by using the target rotating speed for transition time different from that for the steady time when acceleration is not sufficient, and the value of parameter related to a driver's demand for acceleration is larger than a reference value. CONSTITUTION:During operation of an engine, in CPU not shown, a value of parameter related to a driver's demand for acceleration is detected, for example, a throttle opening theta is detected by a throttle opening sensor 52. A reference value theta0 for the throttle opening theta is set as a function of a car velocity. Subsequently, while an acceleration pedal 50 is stepped into largely, if theta>theta0 continues more than designated time, the target rotating speed for transition time is selected as the target engine rotating speed instead of the target rotating speed for steady time. According to the thus selected target rotating speed, a flow control valve 38 is controlled, and an escape valve 32 is controlled to adjust line pressure Pl to the minimum value for avoiding a slip of a belt 26 of a stepless speed change gear 10.
