Title: Optical multiplexer device
Inventor: WATANABE HIDEO
IPC: G02B6/122
Filed: 1985-04-03
Abstract: PURPOSE:To reduce the side of a device and easily adjust respective elements, and to eliminate the need for readjustments during use by converging light beams from plural laser light sources on one point by a grating lens provided on a top surface waveguide plate. CONSTITUTION:The light beams from the semiconductor lasers 1-3 are converted on one point P1 through an optical waveguide layer 4B on the substrate 4 and the grating lens 5. The lens 5 consists of parts 5A-5C having gratings which are sectioned corresponding to incidence positions of the light beams 1a-3a and differ in pitch and direction from one another, and the incident light is diffracted, converged on the point P1 and made into parallel light through a collimator lens 6. Therefore, the plural light beams are multiplexed extremely easily and respective elements need not be positioned with high precision; and the light sources are adhered directly, so the device is reduced in size.

Title: Light emission module
Inventor: KASHIWAGI KEIZO
IPC: G02B6/42
Filed: 1989-03-24
Abstract: PURPOSE:To input a stable light signal to an optical fiber which differs in core diameter without adjusting the current of a light emission diode by tapering the inner peripheral surface of a receptacle so that the diameter increases gradually from the insertion end part for the light emitting diode, and further making the external diameter of a ferrule proportional to the core diameter of the optical fiber. CONSTITUTION:The inner peripheral surface of the receptacle 11 is tapered so that the diameter increases gradually from the insertion part for the light emitting diode 12 to the insertion side for the optical fiber 14; and the external diameter of the ferrule 13 is proportional to the core diameter of the optical fiber 14. Consequently, the photodetection angle of a light signal inputted to the optical fiber 14 can be held constant irrelevantly to the difference in core diameter. Therefore, even when optical fibers 14a and 14b which differ in core diameter are used selectively, the light signal which has the same intensity can be inputted. Thus, without necessilating to adjust the current of the emitting diode 12, the stable light signal can be inputted by using an optical fiber with the different core diameter thereof.

Title: Transformer for high frequency heater
Inventor: NAKAMURA MASAMI
IPC: H01F27/30
Filed: 1990-03-20
Abstract: PURPOSE:To reduce the number of input windings and to reduce size, weight and cost of a transformer by disposing the winding by avoiding a gap of a U-shaped magnetic cores of the same material and shape. CONSTITUTION:Magnetic cores 4, 4' are formed of U-shaped cores of the same material and shape. Input windings 1 are mounted by avoiding the gap positions of the U-shape cores, and the gap is located at the intermediate between the winding 1 and a high voltage secondary winding 2.

Title: Broadcast signal detecting circuit
Inventor: FUJITA MASAHIRO
IPC: H04N5/44
Filed: 1980-05-29
Abstract: PURPOSE:To ensure accurate detection of a synchronous signal regardless of severe fluctuation of the field intensity, by integrating a synchronous signal passed through an analog switch that is controlled by a BLK pulse (blanking flyback pulse) and controlling a switching circuit with the integrated synchronous signal. CONSTITUTION:A synchronous signal of which DC components are interrupted by a capacitor 16 is supplied to the drain of an FET15. The FET15 is controlled by the BLK pulse which is applied to a gate. On the other hand, the both-end terminals voltage of a capacitor 19 is higher than the base-emitter voltage of a transistor (TR)21 in case a synchronous signal is supplied. Thus the TR21 is turned on. The TR21 is turned off with no input of synchronous signal. As a result, the broadcast signal is detected stably regardless of a severe fluctuation of pulse duration.

Abstract: PURPOSE:To solve the safety and durability problems of electrical parts caused by the moisture-condensation around the driving part of an electrode-driving apparatus without complicating the mechanism of the apparatus, by introducing the exhaust air from the fan for the cooling of the condenser of a refrigerator to the driving apparatus. CONSTITUTION:The titled high-frequency thawing apparatus is composed of the thawing chamber 1 containing the material 7 to be thawed, the high-frequency oscillator 10 to supply high-frequency energy, a pair of heating electrodes 5,6 radiating high-frequency radiation, the electrode-driving apparatus 9 to drive the heating electrodes vertically, and a refrigerator to introduce chilled air into the thawing chamber 1. In the above apparatus for the dielectric thawing, the air exhausted from the fan 13' for the cooling of the condenser 12' of the refrigerator is guided to the electrode-driving apparatus 9. Since the air blasted to the apparatus 9 is heated by the heat taken from the condenser 12', the temperature decrease of the apparatus 9 by the thermal conduction through the driving shaft 8 can be avoided and the moisture-condensation around the apparatus 9 can be prevented. Consequently, the safety of the apparatus against the moisture-condensation around the electrical parts can be improved.

Title: Noncontact-type radiating fin
Inventor: NAGASHIMA KENICHI
IPC: H05K7/20
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a noncontact-type radiation fin which eliminates the use of an adhesive by a method wherein heat which is generated from a heating element is conducted to the radiating fin not by a heat conductor but by radiation. SOLUTION: A heating element 101 is supported by a plate 106. The heating element 101 generates heat, and the heat is conducted to a radiating fin 102 as primary radiation 104. In addition, the heat is conducted further to another radiating fin 102 as seconday radiation 105 from the radiating fin 102 which receives the primary radiation 104. Thereby, the heat which is conducted to the radiating fins 102 from the heating element 101 is dissipated finally to the open air which flows toward a direction 103. In this manner, even when the radiating fins are not brought into direct contact with the heating element by using an adhesive, the heat which is generated from the heating element can be dissipated with good efficiency to the open air from the radiating fins.

Title: Traffic lane running-away alarming device

Filed: 1993-03-30
Abstract: PURPOSE:To hold a part forced out from a traffic lane to be always constant, and to attain stable traffic lane running-away alarm by changing the one-dimensional picture element coordinates of the traffic lane so that the vehicle part force out from the traffic lane to be always constant at the time of the generation of the alarm. CONSTITUTION:A signal processing means binarizes the picture signal of the traffic lane obtained from a line camera by a threshold value Th, and searches picture element coordinates a1 and a2 of the both side traffic lanes from the picture element position of a horizontal center line. Then, the picture element coordinates a1 and a2 are converted into picture element coordinates b1 and b2 according to a speed detected by a speed sensor. That is, when the speed is higher than the state of the binarized traffic lane picture signal, the traffic lane picture signal is converted from the actual traffic lane (dotted line) into the virtual traffic lane (actual line), and the picture element coordinates are narrowed from a1 and a2 to b1 and b2. On the contrary, when the speed is lower, the picture element coordinates b1 and b2 are widened. Then, a distance between the traffic lane and a vehicle is searched, and when the distance is less than a constant value, and a winker is not operated, an alarming device is energized.
