Title: Heat exchanger cooling fan for automobile
Inventor: EZAKI NOBUYUKI
IPC: F04D29/38
Filed: 1989-08-30
Abstract: PURPOSE:To shorten a driving torque so as to form good mixed flow having layout property, by forming the front surface shape of a blade serving as swept back skew extending from the bottom part to the top thereof, and forming the rotating locus of the blade side surface so that a windward is formed symmetrically with a leeward to the center shaft thereof. CONSTITUTION:The front surface shape of a blade 33 is formed serving as a swept back skew which sweeps back in the reverse direction of the rotating direction A of the blade 33 extending from the bottom part to the top thereof, while the rotating locus shape formed on the side surface of the blade 33 is formed so that a windward is formed symmetrically with a leeward to the center shaft of the rotating locus. It is thus possible for flow at the pressure surface of the blade 33 to move easily in a skew flow direction, and enable a blade backward flow to make the skew flow without increasing an installing angle. Even if an engine or the like for obstructing air flow is arranged on the backward of a cooling fan, it is possible to circulate air efficiently so as to improve the fan efficiency and shorten a fan driving torque.

Inventor: SUI AKIRA
IPC: E21D9/12
Filed: 1987-09-09
Abstract: PURPOSE:To improve the yield of material and reduce man-hours in the above- captioned screw for ground boring equipment by winding a plurality of layers of different quality square steel materials spirally around a rotatable mandrel to weld them integrally with each other. CONSTITUTION:A high hardness long square material is wound spirally around a rotatable mandrel in hot working to form a inner diameter side screw 2. Then, a hard square steel material is wound around said screw to form a outer diameter side screw 1. Both screws 1, 2 are welded integrally with each other on portions where earth and sand slide and then the mandrel is withdrawn. Further, both screws are inserted into an outer pipe and welded to the inner surface of pipe to provide an outer pipe type boring screw. Thus, the yield of material is improved and man-hours are reduced.

Title: Drain structure of fuel tank for large heavy machine
Inventor: GONDA TETSUO
IPC: B60K15/03
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To provide the drain structure of a fuel tank for a large heavy machine to open and close a drain pipe simply in a short time and besides hardly soil the hands of a worker during draining. SOLUTION: During draining of fuel in a fuel tank 20, when a cock 23 arranged in the midway part of a drain pipe 22 coupled to a fuel tank 20 is turned to the opening side, fuel in the fuel tank 20 is discharged from a discharge port 22a through the drain pipe 22. As noted above, opening and closing operation of the drain pipe 22 is practicable through simple one action and in a short time. Besides, since a cock 23 does not close a discharge port 23a like a plug a and is of a valve structure wherein in the midway of the drain pipe 22, a fuel flow pipe is closed or opened, there is no fear of the hands of a worker being soiled by fuel flowing out through the discharge port 22a during draining.

Title: Weight measuring instrument for moving vehicle
Inventor: MATSUMOTO SHOICHI
IPC: G01G19/03
Filed: 1986-09-25
Abstract: PURPOSE:To measure the weight of a moving vehicle by picking up an image of the license plate of a vehicle which passes on a weight measuring instrument from a fixed position. CONSTITUTION:An ITV camera 6 at the fixed position picks up the image of the license plate 5 of the vehicle 1 and inputs an electric signal C indicating the size of the license plate 5 to an arithmetic unit 8 through an image processor 7. The unit 8 operates the signal C to decide whether or not the vehicle 1 is on the weight measuring device 2 within a range suitable for weight measurement from the size of the plate 5, and then outputs a measurement period signal D to a weight arithmetic unit 4. The unit 4 inputs a weight signal A from a signal converter as an effective signal in a period specified by the signal D, and calculates and outputs the weight of the vehicle 1 as a vehicle weight signal E. Thus, the weight of the vehicle is measured automatically without stopping the vehicle on the device 2 temporarily.

Abstract: PURPOSE:To improve image forming speed by determining a space between a recording paper and the following recording paper to be fed, and varying the timing of recording paper feeding start according to the paper-to-paper space at the time of consecutive image formation. CONSTITUTION:The ROM of a main body control part 53 stores paper-to-paper three spaces l1-l3 and data D1-D3 to determine them; the distances l1-l3 are selected for the preceding recording paper S1 which is carried in a direction shown by an arrow and for the recording paper S2 which waits at a resist roller 15. When the single side of recording paper S1 is printed and the paper S1 is discharged and the space reaches l1 with data D1, the recording paper S2 is printed at the highest speed with a single side printing mode by driving a roller pair 15 and a paper feeding roller pair 14. When single-side printing is performed on the following paper S2 and then it is carried to a job separator 4, printing is performed on the recording paper S2 by restarting the paper at the time when the space reaches l2 by means of the data D2. In a double- sided printing mode, after single sided printing is performed on both the recording papers S1 and S2, they are carried to a double-sided unit; then, printing is performed by restarting the recoding paper S2 at the time when the space for paper reaches l3.

Title: Code converting circuit
Inventor: OSUMI MASAKO
IPC: H03M5/16
Filed: 1985-10-08
Abstract: PURPOSE:To remove a code error from an output binary signal even if a noise is generated in a ternary signal by controlling level detection alternately so that the detection of one level discriminating signal is inhibited at the timing that a prescribed level signal is detected from the other level discriminating signal. CONSTITUTION:In accordance with a level discriminating signal 104 sent from a comparator 2 and a control signal 108 inputted from a control circuit 4, a data storing circuit 5 outputs a level signal corresponding to the discriminating signal 104 as a level signal 106 only at the timing that the signal 108 is in the H level. Thereby, the signal 106 in the H level is detected by the storing circuit 5, and when the signal 106 is turned to the L level, a level signal output function through the storing circuit 5 is inhibited through control action based upon a control circuit 4. The level output function is transferred to the storing circuit 6 side and an unnecessary signal due to the level discriminating signal 104 is cut off and is not outputted from the storing circuit 5. A noise included in a discrimination signal 105 outputted from a comparator 3 is also similarly removed and is not outputted from a storing circuit 6.

Filed: 1982-12-21
Abstract: PURPOSE:To extend the life of a tape and prevent the tape from sticking to a rotary head cylinder and reduce the power consumption of a device, by controlling the rotation and the stop of a rotary head part interruptedly in the state where the tape is wound around the cylinder at the tape running stop time. CONSTITUTION:When a VTR is set to a stop mode, a microcomputer 11 starts an m-minute timer and stops a cylinder motor for m-number of minutes to wait for the next input. Tape running (recording, reproducing, quick traversing, rewinding, or the like) or tape unloading is inputted. When one of them is inputted, the VTR is returned to a normal running mode or the like. If it is not inputted for (m) minutes, an l-minute timer is started, and a turn-on command is issued to a cylinder motor to rotate it, and the device waits for the input. If there are no inputs for (l) minutes, a loop counter is counted up by one. When the counted value of the loop counter is smaller than a certain value (a), the m- minute timer is started again, and the cylinder motor is stopped to wait for the input, and the same operation is repeated. When the counted value of the loop counter becomes the value (a), the tape is unloaded, and the power of the device is broken after completion of unloading.
