Patent JP-S56134841-A (JP)
Title: Switch mechanism
Inventor: TOUDOU AKIRA
IPC: H03J1/16
Filed: 1980-03-25
Abstract: PURPOSE:To prevent slippage of a set frequency, by controlling the lock of the tuning knob by the locking means in relation to switching of the switch. CONSTITUTION:Knob 14 is pressed upward against spring 17. The lock of dial knob 15 is released, and power of the sound amplifying part is turned on to set the whole of the receiver to the operation state. While pressing knob 14 upward still, dial knob 15 is moved to perform the tuning operation. After the completion of the tuning operation, knob 14 pressed upward is released. Then, knob 14 is pressed downward by the deflecting force of spring 17, and detaining piece 16 at the lower end of knob 14 is brought into contact with dial knob 15 to lock it. Consequently, dial knob 15 is prevented from moving to generate slippage of the tuning point. By downward movement of knob 14, switch 12 is turned off to cut off the power supply path of the sound amplifying part, and thus, the receiver is set to the emergency alarm broadcast holding state.

Title: Distance detection apparatus for vehicle
Inventor: KIKUCHI HAYATO
IPC: G01S17/93
Filed: 1994-03-09
Abstract: PURPOSE:To detect only a distance up to an object existing within a required range, to enhance the responsivity and the measuring accuracy of a distance detection apparatus and to prevent a malfunction by a method wherein the detection angle range of the distance detection apparatus is reduced according to a rise in the running velocity of a vehicle. CONSTITUTION:As the running velocity V of a vehicle 9 rises, an electronic control unit 131 operates a detection angle range theta by means of an operation expression which contains the velocity V and the transverse acceleration alphaof the vehicle as well as the set time (t). Then, the transmission and the transmission stop of individual transmitters 111 to 11N are controlled so as to satisfy the angle range theta. Consequently, a distance up to an object which is deviated from a revolvable range is not detected meaninglessly, and the number of detection data can be reduced. Thereby, the data processing time of the distance detection apparatus can be shortened, its responsivity can be enhanced, and a possibility that a malfunction is generated can be lowered. In addition, when a detection range is reduced, the number of detections with reference to the object within the detection range is increased, and the detection accuracy can be enhanced due to an averaging effect.

Inventor: HATTORI JUN
IPC: H01P5/12
Filed: 1991-03-05
Abstract: PURPOSE:To easily and continuously set the power distribution ratio by having only to adjust a phase shift angle of a variable phase shifter. CONSTITUTION:When a power is supplied to an input terminal 20 while a phase angle of a variable phase shifter 28 inserted between directional couplers 12, 14 interconnected by a main transmission line 16 is set zero, the power is not outputted to an output terminal 22 but outputted to an output terminal 26 only. Moreover, when a power is supplied to the input terminal 20 while a phase angle of the variable phase shifter 28 is set to pi, the power is not outputted to the output terminal 26 but outputted to the output terminal 22 only. Thus, the distribution ratio of the power outputted from the output terminals 22, 26 is regulated by adjusting optionally the phase angle of the variable phase shifter 28 is set within 0-pi.

Title: Production of porous oxide sintered compact
Inventor: TSUCHIYA WATARU
IPC: C04B38/02
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To obtain a porous oxide sintered compact with fine and uniform pores at low cost by feeding a mold of desired shape with a solution of a complex prepared by adding an amino acid to a metal nitrate followed by heating the solution to its boiling point or higher and then sintering the resultant porous body. SOLUTION: This porous oxide sintered compact, which is an alumina sintered compact 30-70% in porosity, is obtained by feeding a mold of desired shape with a solution of a complex prepared by adding an amino acid to a metal nitrate in such an amount as to be 0.3-2.5 molar times the total mols of the metallic element (not specified, provided that the corresponding nitrate clan be prepared; e.g. Al, Ni, Zn), followed by heating the solution to eliminate the solvent to effect self-combustion of the residuals and instantaneously generate large quantities of gases such as carbon dioxide and nitrogen to produce a fine porous body with mold shape which is then sintered at a temperature proper for the corresponding material characteristics. In the above process, the amino acid serves as a fuel for the combustion as well as contributes to improving the solubility of the nitrate.

Filed: 1992-02-26
Abstract: PURPOSE:To make it possible to diagnose the NN-virus infection of fish by detecting the antibody of anti-brain-cell necrosis NN virus in the serum of fish by an immunological means. CONSTITUTION:As a specimen, the serum of fish is used. The serum is sampled from the fish. The fish serum can be used in the intact state. However, it is preferable to pick up 1gM fraction and to use the serum because the sensitivity is improved. The immunological means is not especially limited when the means is the immunological measuring method utilizing antigen-antibody reaction, and there are an ordinary competition method and the like. For example, when the competition method is adopted, the anti-NN-virus antibody in the specimen and a specified amount of the insolubilized anti-NN-virus antibody are made to react competitively with a specified amount of the NN-virus antigen, which is labeled with label agent. Then, the insolubilized NN-virus antibody and the label antigen are separated. Thus, the anti-NN-virus antibody in the specimen can be detected by measuring the label activity of either of the antibody or the antigen.

Title: Dimension measuring instrument
Inventor: KOYANAGI HIDEO
IPC: G01B11/02
Filed: 1988-02-22
Abstract: PURPOSE:To accurately measure the dimensions of an object to be measured irrespectively of the position of the object by providing a parallel ray projecting means, light receiving lens with a diaphragm, photoelectrically converting section, and signal processing means. CONSTITUTION:A photoelectrically converting section 5 is provided on the outside of the image forming position of an object to be measured within a moving extent 3a-3b. Ratios of the full-shadow section and half-shadow section in the output of the photoelectrically converting section 5 are respectively different when the object to be measured is at the farthest location and nearest location of a light receiving lens 4. When the waveforms are compared, the full-shadow section becomes larger and the half-shadow section becomes smaller at the nearest location. The width of the half-shadow section is proportional to the distance between the light receiving lens and the image forming position. Therefore, the dimensions of the object 3 to be measured can be measured by utilizing the sizes of the full-shadow and half-shadow sections through the lens 4 with a diaphragm by projecting parallel rays of light on the object 3 from a light source through the lens 4.

Air is exhausted from a exhaust pipe 106, the heating is executed for 1 hour at 250 deg.C, and the exhaust pipe 106 is sealed to terminate the sealing.  The volume shrinkage is generated on the alloy of the electrode by the deposition of the intermetallic compound at 320 deg.C, and the compressive strain caused by the difference in the thermal expansion coefficients between that of the substrate and that of the alloy is relaxed, so that the occurrence of projections is inhibited.
