Patent JP-H0669723-A (JP)
Title: Yagi antenna
Inventor: YASUDA TAKESHI
IPC: H01Q19/28
Filed: 1991-03-28
Abstract: PURPOSE:To electronically rotate directivity by electronically adding auxiliary elements so that the sizes of non-feeding elements to be constituted equivalently correspond to a waveguide and a reflector so as to change them. CONSTITUTION:The non-feeding elements 1 arranged before and behind the feeding elements 2 at prescribed intervals are constituted so that the auxiliary elements 3 which are added to the tips by electric insulation can be made intermittent by control elements 4. The control elements 4 are fitted to the non- feeding elements 3 installed before and behind the feeding elements 2 so that the elements are inversely conducted. When positive voltage is impressed on the elements 4 through a conductor 5, one element is added with the auxiliary element 3 so as to operate as the reflector and the other operates as the waveguide since the auxiliary element 3 is not added to it. Thus, the antenna has directivity in the direction of the element to which the auxiliary element 3 is not added. When negative voltage is impressed, the element to which the auxiliary element 3 is added is inverted and therefore directivity is also inverted.

Title: Discharge lamp lighting device
Inventor: KIDO SHOJIRO
IPC: H05B41/24
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent the excess output in a step-up circuit in control mode switching by installing a means which conducts switching of a target value of output power or output current earlier than the switching of a threshold value in the switching operation of a PWM control part for conducting duty control of a switching element and a peak current control part. SOLUTION: When the lighting state of a discharge lamp is moved from a starting state to a stable state, the switching of a target value Vref1 of output current in a PWM control part 6 is relatively preceded than the switching of the reference value Vref2 of switching current Ip in a peak current control part 7. Concretely, a delay circuit 7d such as an integrating circuit of RC is installed at reversely input end of a comparator 7b of the peak value control part 7, and timing of the reference value Vref2 switched to be actually inputted to the comparator 7b is delayed.

Title: Measurement of phase error for magnetic disc medium
Inventor: OHARA SHUICHI
IPC: G11B5/84
Filed: 1987-05-29
Abstract: PURPOSE:To cancel a phase difference between main and subgaps, by arranging secondary higher subgaps at positions set at equal distances from the main gap on both sides thereof to add up signals obtained from the subgaps. CONSTITUTION:Subgaps 2 are arranged at an equal distance on both sides of a main gap 1 along the radius of a disc. A recording/reproducing circuit is connected at both ends of a coil produced by connecting windings 4a and 4b of the subgears 2 in series, reproduction signals from subtracks 13a and 13b are added up with a coil to make a reference signal and a phase error of a recording medium is measured on the basis of this signal. Thus, a signal can be obtained with the phase the same as a signal of the main gap by adding reproduction signals obtained from the subgaps. A reference signal is generated following the signal, thereby removing adverse effect due to a positional deviation between the main and subgaps.

Title: Recording device
Inventor: NAKAZAWA AKIRA
IPC: B41M5/00
Filed: 1990-05-25
Abstract: PURPOSE:To make the title device in simplified, compact design with voltage for recording lowered by applying the voltage to an intermediate electrode for formation of protrusion for electric conductive ink in a timing not being lag behind the voltage-applying to an electrode. CONSTITUTION:An ink protrusion 11 is formed by applying a pulse A in 0.3ms duration at 200V to an intermediate electrode 6. Then a pulse B in 0.7ms duration at 500V is applied to an optional electrode 2 in a timing not earlier than the application of the pulse A, and thereby the ink is made to fly for recording. The reason why the applied voltage that is normally required to be at 800V for applying to the electrode can be reduced to 500V for execution of the recording is formation of the ink protrusion that is made by applying the voltage to the intermediate electrode 6. The application of the voltage to the intermediate electrode 6 may be made at as low level and for a short period of time as mentioned above. The voltage application to each of the electrodes is made by recording commands given through a control circuit 12. The recording is made with an ink supply roller 1, recording paper 3, and a screen 4 moved in the direction indicated by the arrows.

IPC: G01N27/20
Filed: 1984-06-28
Abstract: PURPOSE:To find the staining of an insulator in its early stage by connecting the ground side of the insulator to a steel tower through a conductor, and detecting the staining of the insulator from a leak current which flows through the conductor. CONSTITUTION:An insulator string 10 to which the conductor 11 and a single- mode optical fiber 12 are fitted is fitted to the steel tower 3 selected so as to detect the staining of an insulator 1. The conductor 11 is coiled and connected at one terminal 11a to the cap 1a of the ground-side insulator 1 and to the steel tower 3 at the other terminal 11b; and the single-mode optical fiber 12 is run through the coiled conductor 11 and both its terminals are connected to the detecting device body provided at a proper position of the steel tower 3. When the insulator 1 is stained more and a leak current flowing through the conductor 11 increases, magnetostriction effect occurs in a magnetostrictive material 13 such as an Ni-Co alloy covering the optical fiber 12, and consequently the optical fiber 12 is strained axially, so that the light beam propagating in the optical fiber shifts in phase.

Title: Automatic controller
Inventor: OUCHI SHIGETO
IPC: B21B37/00
Filed: 1985-06-21
Abstract: PURPOSE:To attain the highly accurate and stable control with an automatic controller by using a multi-variable control means and switching this control means to a PID control means if the controlled variable has a big difference from a target amount. CONSTITUTION:When the tension between rolling stands 1 and 2 has fluctuation by some reason, this fluctuation is detected by tension detectors 16 and 26. Then the differences between detected tension levels sigma1 and sigma2 and their target values are sent to tension controllers (MZR)15 and 25 as well as to a multi- variable control circuit 50. Switches 17 and 27 are usually closed and the highly accurate control is performed based on the optimum control logic. When big differences exist between levels sigma1 and sigma2 and their target values, the control may possibly unstable with the optimum control logic only. Thus switches 17 and 27 are opened together with switches 18 and 28 closed respectively for execution of the PID control.

Filed: 1988-06-01
Abstract: PURPOSE:To prevent the drop of splashed fuel on a fan, by a method wherein, in the vaporizing device of a vaporization type liquid fuel combustion device, the vaporizing surface of a vaporizing cylinder is formed in a taper in which the size thereof is increased in the direction of the flow of air for vaporization in a vaporizing cylinder. CONSTITUTION:A vaporizing surface 34 of a vaporizing cylinder 19 is formed in a taper in which the size thereof is increased in the reverse direction to that of the flow of air for vaporization or that toward a combustion fan 29 in the drawing. In this constitution, a shock force when atomized fuel from a shake-off plate 24 is collided with the vaporizing surface 34 is decreased because of the vaporizing surface 34 being formed in a taper, and re-splashing occasioned by collision is suppressed. Further, even if the fuel re-splashes, it is collected to the downstream side of an air flow for vaporization and is suppressed from splashing of it to the combustion fan 29 side. This constitution enables prevention of flying of fuel.
