Filed: 1987-06-24
Abstract: PURPOSE: To improve the radiating efficiency of a cage type antenna without making the transmitting frequency band narrower, by cylindrically stretching outside conductors around a post and connecting the upper sections of the outside conductors with a central conductor, and then, adding guy wire loadings stretched from the upper sections of the outside conductors to the ground.  
     CONSTITUTION: Auxiliary antennas 16 are stretched at regular intervals around a central conductor composed of an iron post 12 and both ends of outside conductors composed of antenna loading wires 18 are connected with each other with a ring. Moreover, a guy wire 19 is stretched from each outside conductor to a prescribed location on the ground. At the upper section of this antenna, the outside conductors are short-circuited or connected by means of inductance L with the central conductor and power feeding is performed at the lowermost sections of the outside conductors. Therefore, a small-sized antenna having a sufficiently high radiating efficiency can be obtained without making the transmitting frequency band narrower. In addition, this antenna can be constructed with a little constructing work when an already existing post is utilized.

IPC: G02B6/12
Filed: 1985-07-17
Abstract: PURPOSE:To realize stable single vertical mode oscillation by a method wherein a photodetection element is formed adjacent to the active region of a laser with an insulation film in between and the position of the junction of the element is the same as the position of the active layer of the laser. CONSTITUTION:When bias voltage is applied to a laser part with a terminal 13 as positive side and a terminal 14 as negative side, single horizontal mode oscillation is generated in an active layer 4 directly above a groove. At this stage, reverse bias voltage is applied to the junction of N-type and P-type GaAs layers 10 and 11 with a terminal 15 as negative side against the terminal 13. Near-sight distribution of the light parallel to the junction plane of the active layer in a cavity is spread wider than the width of the groove and a part of the light distribution is absorbed by the junction of the N-type and P-type GaAs layers 10 and 11 through the SiO2 film 9 and an APC operation, which stabilizes light output of the laser, is carried out by using the signal of that absorption. The laser is a complex cavity laser which has three cavities l1, l2 and l3. A wavelength, whose gain distributions of three cavities interfere among them is selected. With this constitution, single vertical mode oscillation can be generated.

Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To avoid light emission defective parts caused by a light emitting element by variably constituting the relative position of a light emitting means and a slit. SOLUTION: The relative position of a light emitting device 0 and a slit 4 is made possible to freely set in a main scanning direction and a sub-scanning direction by a fixing member 8. The light emitting device 0 and the slit can be also constituted in a freely detachable manner. When a light emitting element partially short of quantity of light is present, an image is transferred to printing paper in such a state that a part insufficient in image formation is partially present because of the insufficiency of exposure. At this time, by moving the slit 4 in the main scanning direction and the sub-scanning direction to again perform printing operation, an image can be brought to a good state.  By this constitution, even if a light emission inferior part such as a flaw is generated in a light emitting part, utilization avoiding the inferior part can be performed and, therefore, good exposure can be obtained and good recording can be performed.

Inventor: YANAGIDA NOBUYOSHI
IPC: B23K9/23
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To reduce tensile residual stress by simple constitution by utilizing thermal shock strain. SOLUTION: By rapidly cooling a surface region whose temperature is raised by heat input of welding by jetting a coolant from a nozzle 11 to a region of the surface of a weld zone which is in the state of tensile stress, transient temperature difference is generated between the surface and a layer just under a surface layer. In this way, the tensile thermal shock stress is added on the surface layer, tensile strain is generated and also the surface layer is partially yielded. Next, by stopping cooling and raising the temperature, the thermal shock stress is eliminated. The surface of the weld zone is improved into a state where deformation is elastically recovered from the partially yield state and tensile stress is mitigated, or a compressive residual stress state.

Filed: 1980-11-10
Abstract: PURPOSE:To prevent wasteful power consumption by controlling the energizing of a boosting circuit for a strobe tube by using a time limit signal for a certain period outputted by a timer circuit of a camera. CONSTITUTION:A main switch 16 of a camera 10 is closed, and when a trigger switch 20 is closed after this, the signal of an H level is outputted for a prescrib ed period from the output end O of a timer circuit 18. When the output voltage of a boosting circuit 52 in a strobe device 12 arrives at the light emittable voltage of a strobe tube 68, a neon tube 64 emits light. Upon lapse of a prescribed period after closing of the switch 20, transistors 22, 24 are nonconducted, although shutter operation is not carried out. Therefore, a display control circuit 26 is de-energized and photometry is stopped; at the same time, the light emission of a display element 28 for exposure is stopped. The circuit 52 is de-energized, and the current from an electric power source 50 does not flow through the circuit 52; hence, wasteful consumption of the power source 50 is prevented.

Title: Multiplier
Inventor: YAMASHITA HIROMITSU
IPC: H03D3/02
Filed: 1984-07-25
Abstract: PURPOSE:To decrease greatly the numbe of component elements of a multiplier by controlling the level of the circuit current within the multiplier from outside and controlling the amplitude itself of the multiplication output. CONSTITUTION:The input signal supplied from a terminal 1 is applied to the bases of transistors TR9 and 12 which form the 1st and 2nd differential transistor pairs. While the signal passed through a phase unit 2 is applied to the base of a TR7 forming the 3rd differential transistor pair. These two signals are multiplied by three differential transistor pairs. The TR13 has its base connected to a variable resistor 24 and therefore applies the current accordant with the base voltage to the 3rd differential transistor pairs 7 and 8. Thus the amplitude of the multiplication output can be controlled through the control given to the base voltage of the TR13 by the resistor 24. Thus the use of attenuator is omitted to decrease greatly the number of component elements.
