Title: Lighting system for position detector for unmanned carrier
Inventor: HATADA FUMIO
IPC: G05D1/02
Filed: 1988-02-19
Abstract: PURPOSE:To uniformize the light emitting quantity of each LED by giving a high voltage to occur by the energy accumulated at an inductance to many serially connected LEDs. CONSTITUTION:When a transistor (TR)2 is turned on, a current starts to flow at the serial circuit of an inductance 1, a TR2 and a resistance 6 and the terminal voltage of the resistance 6 rises. When the base potential of a TR9 rises and is higher than a reference voltage Vref given to the base of a TR7 accompanying to this, the TR9 is turned off and the TR7 is turned on. Accompanying to this, a TR10 is turned on, a collector becomes a low order, an oscillator 3 becomes the low order and the TR2 is turned off. The collector voltage is higher than a supply voltage VCC, the energy accumulated at the inductance 1 is discharged through the serial circuit of LED4, 4..., a high voltage is added to the serial circuit and a driving current flows. Thus, the light emitting quantity of each LED can be uniformized.

Title: Surface mounting type balun transformer
Inventor: WAKAMATSU SUSUMU
IPC: H01F19/06
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a surface mounting type balun transformer the mounting area of which is small. SOLUTION: This is a surface mounting type balun transformer, in which dielectric sheets carrying single spiral inductors L1 -L4 are laminated. Then, a capacitor formed between a capacitor electrode 3 and a ground electrode layer 6 is connected with an unbalanced terminal 4 in parallel with a primary balun line. That is, frequency characteristic can be adjusted so as to be made lower by the capacitor, and the strip line length of each spiral inductor L1 -L4 can be made shorter than λ/4. Thus, areas carrying the spiral inductors L1 -L4 can be reduced, and each sheet can be obtained with a small area. Then, when the dielectric sheets carrying the single spiral inductors are laminated, the mounting area can be made as small as possible.

IPC: B21D5/08
Filed: 1980-03-26
Abstract: PURPOSE: To apply a comparatively large rolling load in order to roll form a ribbed H-beam having the rib bent in a sharp curvature, by arranging three inner rolls against the loading point of the outer roll in order to share the rolling load.  
     CONSTITUTION: In a stand for applying a straightening process and a rib-forming process, a couple of upper and lower inner rolls IR is arranged against an outer roll OR 4 . In which, the inner rolls IR are constituted of three units, that is the middle inner roll IR c  located at the loading point of the outer roll OR 4 , and the inner rolls IR f  and IR r  located before and behind the middle inner roll IR c . Hereupon, the diameter of the left and the right inner rolls IR f , IR r  is made a little larger than that of the middle inner roll IR c  for the purpose to uniformly distribute the rolling load upon three rolls. Hereby, since the large rolling load to be applied to the middle inner roll IR c  is shared by the left and the right inner rolls IR f  and IR r , three inner rolls can endure the large rolling load so that a small sized, ribbed H- beam having the rib bent into a sharp curvature can be formed.

Title: Concrete placing method using plurality of nozzles on pipeline concurrently and device therefor
Inventor: MATSUI NOBUYUKI
IPC: E04G21/04
Filed: 1994-03-09
Abstract: PURPOSE:To eliminate a danger of clogging a pipe and efficiently place concrete independent of a concrete property, by providing main piping with a pressure sensor for branching a concrete flow to a nozzle via a flow dividing valve and detecting the pressure of a main pipe and a branch pipe. CONSTITUTION:The first to fourth flow dividing valves 8 are throttled to operate a pump P, and a pressure difference on the pressure gauges 20a to 20f of nozzles 9 are examined. When the difference is outside the range of the preset value, a drive device for the valves 8 is actuated, thereby averaging pressure values. Then, the averaged pressure value is transmitted to the arithmetic device of a control panel 25, thereby making judgement about a pressure difference between main pipe lines 7a and 7b. When the difference is outside the range of the preset value, the adjusting devices 18a and 18b of flow dividing valves 18 are adjusted. Then, nozzle pressure is examined and when the pressure is low, a screw drive device is actuated to adjust the flowrates of the valves 8. Also, the reduction of a total flowrate and the stop of a flow are effectuated by means of delivery control and solenoid valves 22a and 22b. According to this construction, concrete always flows in the main pipe 7 and the branch pipe, thereby ensuring freedom from a danger such as a property change or pipe clogging.

Abstract: PROBLEM TO BE SOLVED: To provide a discharge muffler shape to improve a silencing effect due to reflection and interference of sound rays. SOLUTION: Only in the region, where sound rays radially extending from a discharge port 8c serving as a starting point do not reach, of an annular region wherein the outer periphery of the boss part 8a of a bearing disc 8 and the inner periphery of the opening 15a of a discharge muffler 15 are positioned facing each other, an opening part 20 through which gas discharged from the discharge port 8c is formed between the outer periphery of the boss part 8a and the inner periphery of the opening 15a of the discharge muffler 15.  Since after the sound rays of a sound generated by pulsation occurring when gas is discharged through the discharge port 8c are collided with and reflected by one of the outer peripheral surface of the boss part 8b and the inner wall surface of the discharge muffler 15, the sound rays pass through the opening part 20, this structure increases damping of a sound due to interference and reduces the generation of operation noise.
