Title: Laminated integrated waveguide device and its production
Inventor: IMOTO KATSUYUKI
IPC: G02B6/13
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a laminated integrated waveguide device that an optical integrated circuit with a high integration degree and high dimensional accuracy can be realized, and to provide its production method. SOLUTION: Since waveguide layers having various characteristics and functions can be laminated into a multilayered state, an optical device with a high integration degree can be realized in a small substrate area. The upper faces of core layers 3-1, 3-2 consisting of a photobleaching material and of clad layers 4a-1, 4b-1, 4a-2, 4b-2 on both sides of the core layers 3-1, 3-2 can be made flat, and the upper clad layers 5-1, 5-2 on the clad layers 4a-1, 4b-1, 4a-2, 4b-2 can be also made flat. Each waveguide layer is isolated from others by a UV-cut layer 6-1 to prevent UV rays from transmitting. Thus, the waveguide layers 7-1, 7-2 consisting of a photobleaching material can be formed into a multilayered state.

Title: Synchronous motor exciter
Inventor: WADA EIKICHI
IPC: H02P1/50
Filed: 1977-11-02
Abstract: PURPOSE: To perform synchronous pull-in at optimum timing by detecting the mimimum slip and the optimum phase at the start of a synchronous motor.  
     CONSTITUTION: The exciting power of a synchronous motor 3 is obtained by connecting an excitation power supply 7 to a rotary exciter 4 through a magnetic field contactor 6. The timing to close the magnetic field contactor 6 is determined by setting up a detector 8 to detect frequency and phase and inputting both the output signal of an AC speed generator 5 which is directly connected to the axis of rotation of the motor 3 and revolves and the voltage signal which is removed from the system power voltage by a voltage current transformer 1, respectively. The number of poles of the AC speed generator 5 which is directly connected to the above-mentioned synchronous motor 3 is same as that of the synchronous motor 3 and the relative position of a mechanical stator also matches. This matches the frequency and phase of the system power voltage and those of the occurrence voltage of the AC speed generator when the synchronous motor reaches the synchronous r. p. m.. As a result, a desired synchronous pull-in can be performed.

Title: Incoming call processing system
Inventor: KOYAMA MITSUKAZU
IPC: H04B7/26
Filed: 1988-05-27
Abstract: PURPOSE:To attain the incoming call processing from a general subscriber telephone network subscriber to a mobile station subscriber even at the most frequent time by sequencing the priority of an incoming call from the general subscriber telephone network to an extension in order of a speech extension and then a connection processing extension. CONSTITUTION:Since there is no idle extension in a speech extensions 51, a main control section 6 registers a connection processing extension number to the end of a reservation queue part 61 in the reception state with respect to a call signal coming to the connection processing extension 52 and increases the processing priority every time the head is processed. When the signal reaches the head of the reservation queue part 61 and an idle speech extension 51 is found out, a closing command and an extension designation pickup command are sent to a speech channel unit 71 to be connected to the idle speech extension 51. Then the speech channel unit 71 closes a DC loop and a call signal from the general subscriber telephone network is replied by the extension designation pickup. Thus, the incoming call processing from the general subscriber telephone network subscriber to the mobile station subscriber is applied even at the most frequent time.

Title: Rectifier for pumped-in water vessel
Inventor: GOTOU KIYOUJI
IPC: F04B23/02
Filed: 1978-10-25
Abstract: PURPOSE: To make flow near a suction zone uniform, prevent an air blown vortex and an underwater vortex and improve the suction performance of a pump, by fitting the body of the pump or a suction pipe with a rectifying plate which divides the flow in a water vessel into an upper and a lower portions.  
     CONSTITUTION: A rectifying plate 6, which divides the flow in a water vessel 1 into an upper and a lower portions, is attached to a pump 3 or a suction pipe 4. An appropriate gap is set between the rectifying plate 6 and the wall of the water vessel 1. The plate is so placed in the vessel that water flows freely between the upper and the lower portions because of the gap. Only when the lower portion flows at lower pressure, the upper portion passes through the gap between the rectifying plate 6 and the wall of the water vessel 1 to only supplement the flow of the lower portion. At that time, the upper portion flows very slowly. Therefore, flow separation and vortexes hardly take place in the downstream part of the suction pipe 4. On the other hand, the lower portion is made directional by the rectifying plate 6 and exerts an effect to smoothly conduct the flow.

Abstract: PURPOSE:To inversely transform the direction of an image picked up picture by providing the light receiving element of two-dimensional arrangement, the vertical transferring means and the horizontal transferring means of a photoelectric-converted signal and a controlling means to switch the transferring direction of one of the vertical and the horizontal transferring means. CONSTITUTION:An up-down counter 11 counts an input clock, and determines the ascending or the descending of it according to a switching control signal from an external part. A multiplexer 12 gives a pulse to a horizontal selection line 8 according to the counted result of the counter 11, and the multiplexer 12 becomes operable during the input of a selecting pulse, and generates the pulse in prescribed sequence so as to turn on vertical MOS switches 3. An accumulated charge signal is transferred vertically. Similarly, horizontal MOS switches 6 are turned on in the prescribed sequence by the pulse of the multiplexer 14, and the accumulated charge signal is transferred horizontally. By switching the sequence in which the switches 3 or 6 are turned on by the up-down counter and the multiplexer, i.e., the vertical or the horizontal transferring direction, by external instructions, the direction of the image picked up picture is reversed.

Title: Direct current regulated power supply circuit
Inventor: NAKAJIMA AKIO
IPC: G05F1/56
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To protect an output transistor(R) from being damaged by a loss generated from the output TR by providing this DC regulated power supply circuit with a drive current suppressing means and suppressing a driving current in accordance with the increment of inter-terminal voltage between input and output terminals. SOLUTION: A low loss type DC regulated power supply circuit 20 connecting a PNP type output transistor (TR) Q1 between an input terminal P1 and an output terminal P2 as a through element is constituted of two chips of the TR Q1 and a control circuit A0 attained by an integrated circuit integrating remaining circuit elements. A drive current suppressing circuit A5 is connected between terminals P11, P13 in the circuit 20, and when the voltage Vi-o between the input and output terminals P11, P13 is boosted more than a previously determined value, the circuit A5 forces a base driving circuit A4 to lead in a driving current Id. Consequently the power loss of the output TR Q1 when the voltage Vi-o is high can be suppressed and the output TR Q1 can be protected also at the time of output short-circuit.

Title: Automatic light quantity controlled flash light emission device
Inventor: NAKAYAMA YASUO
IPC: H02M3/135
Filed: 1978-10-27
Abstract: PURPOSE:To eliminate the generation of unnecessary light radiation and make possible optimization of light quantity control to the subject of a short distance by flowing the current recharging a commutating capacitor to the specified route right after cutting-off of an element which controls a discharge lamp. CONSTITUTION:The discharging current of a main capacitor MC at right after the turning-off of a switching element SW1 flows so as to charge a commutating capacitor CC and a commutating charge accumulating capacitor Cd to the polarity opposite from the initial one by way of a switching element SW2 having an impedance sufficiently lower than that of a discharge lamp Xe, resulting in that no current flows to the lamp Xe at all. Hence, the light emission time of the lamp Xe coincides with the period since the element SW1 conducted and the lamp Xe started emission until the element SW2 conducts and the element SW1 is cut off, thus accurate light quantity control is made possible.
