Title: Dynamic balancer
Inventor: HORIUCHI TAKESHI
IPC: G01M1/36
Filed: 1987-12-25
Abstract: PURPOSE:To command the movement of a balance weights without contact and to facilitate maintenance and inspection, by using light signals. CONSTITUTION:A main body 1 of a balancer has the following parts: a moving mechanism, which moves balance weights 2a and 2b; step motors 3a and 3b, which drive the moving mechanism; and optical sensors 6a-6d, which receive light signal from light sources 5a-5d and control the step motors 3a-3b. The reference positions of the balance weights 2a and 2b and the positions of the balance weights 2a and 2b, when the balancer main body 1 is balanced dynamically as a unitary body, are obtained beforehand. A main shaft 7, on which the balancer main body 1 and a grindstone 8 are mounted, is rotated. The amount of displacement of the main shaft 7 when the main shaft 7 makes one rotation is measured. The amount of unbalance of the main shaft 7 is found based on the amount of displacement. The positions of the balance weights 2a and 2b for balancing are obtained. When the moving instructions for the balance weights 2a and 2b are transmitted from the light sources 5a-5d as light signals and the balance weights 2a and 2b are moved, the main shaft 7 can be dynamically balanced.

Title: Sling conveying holder
Inventor: HORIE HIROMITSU
IPC: B66C1/62
Filed: 1990-11-27
Abstract: PURPOSE:To open or close a holder with only rotation and vertical motion of a floating cam by lowering a device on a hanging load, pushing a contact plate upward, thereby having the floating cam rotated and lowered by a selector means, and making linkage so as to grasp the hanging load in operation. CONSTITUTION:When a holder 1 is shifted and situated on a hanging load 100 and then lowered, a hanging load top face 101 pushes up a contact plate 8 and a floating cam 70 goes up together with a piston member 7. During this upward motion, a cam operating surface 70a comes into contract with a side lower surface of a change-direction hook 63, but since this hook 63 is regulated of its rotation by a stopper 8, the cam 70 rotates around a shaft 71, and the one end is projected upward from a through hole 62 of a cam guidance plate 61. Next, when the holder 1 is pulled up with a sling wire, a casing 6 alone goes up, the cam 70 is inserted into space between guide plates 65, and rotation is regulated, thus it goes down. If so, both upper and lower links 23, 25 are also rotated, thereby pinching the hanging load 100 in between as access of a pair of holding arm 5. When the holder 1 is lifted up, these arms 5 are slung up in a state of holding the hanging load 100 in between.

IPC: H04N1/00
Filed: 1992-11-13
Abstract: PURPOSE:To surely implement picture recording processing by detecting a position of an oscillating guide acted by a progressing torque of a recording medium on a recessed circular-arc guide so as to activate the picture recorder thereby allowing the recording medium to be surely in close contact onto the recessed circular-arc guide with simple configuration. CONSTITUTION:Drive circuits 51A, 51B start a motor with a command of a scanning control section 52 to drive supply and feed rollers 13, 16 thereby leading a raw sensitive member S1 from a hopper 11 and carrying the member onto a photosensing drum 15. When the start part of the raw sensitive member S1 is pressed into contact with a guide plate 19 to lift up the plate 19, the motor is tentatively stopped, the lift-up of the guide plate 19 is sensed by a close contact sensor to recognize that the raw sensitive member S1 is in close contact onto an inner surface of the photosensing drum 15 and the result is informed to a scanning control section 52. Then picture information from a CCD 31 is recorded as a light beam via a picture processing section 32 by a command of the control section 52. Thus, the raw sensitive member S1 is surely in close contact with the inner surface of the guide and after it is detected, the recording is processed and the picture is surely recorded.

Title: Dft matrix data retaining method
Inventor: MORIKAWA MAKOTO
IPC: G06F17/14
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To reduce a storing capacity by removing element data that its own data can decide from other element data from two-dimensional discrete Fourier transfomration(DFT) matrix data so as to retain DFT matrix data from which this element data is removed. SOLUTION: Element data that its own data can decide from other element data is removed from DFT matrix data to retain DFT matrix data from which this element data is removed. For example, 8×8 DFT matrix data making prescribed element data a complex number are given to a data compression part 4 from a DFT processing part 2 as 2n×2m DFT matrix data. In this case, the part 4 removes each element data corresponding to F(2n-k1, 0), F(0, 2m-k2), F(2n-k1, m) and F(2n-a, 2m-b). In this case, k1 expresses a natural number smaller than (n), k2 and (b) express natural numbers smaller then (m) and (a) expresses a natural number smaller than (2n).

Title: Inner and outer separate type air conditioner for cooling and heating operations
Inventor: NAKAGAWA HIDEAKI
IPC: F25B1/00
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent a poor energization of a compressor from being carried out and enable a more precise air conditioning control to be attained by a method wherein an indoor side blower is stopped for several minutes at a later half of a re-energization prohibiting time of a compressor ranging from a stopped operation of the compressor to its recovering operation and thereafter the blower is stopped and a pressure balance control for the compressor is carried out. SOLUTION: In the case that an inner or outer separate type air conditioner is operated, its time is counted by a time counter after an operation of a compressor is stopped, both operation and stopping of the indoor blower are controlled in reference to the counted time. That is, the indoor blower is stopped for several minutes at a later half part of a re- energization prohibiting time of the compressor ranging from a stopped operation of the compressor to its recovering state, thereafter the indoor blower is operated again, thereby a pressure balance control for the compressor is carried out.  Or the indoor blower is stopped for several minutes at a former half part of the re-energization prohibiting time of the compressor ranging from the stopped operation of the compressor to its recovering state and the pressure balance control for the compressor is prevented from being carried out. With such an arrangement as above, a pressure difference between a high pressure and a low pressure is reduced and a poor energization of the compressor is prevented.

IPC: H01L31/10
Filed: 1989-12-19
Abstract: PURPOSE:To lessen an SPD in area, to dispense with a photometric amplifier, and to make a circuit small in scale by a method wherein an automatic focusing SPD is divided into three pieces, a central SPD is made slightly smaller than a near infrared LED image in width, and the sides of the central SPD adjacent to other SPDs are formed polygonal. CONSTITUTION:An automatic focusing silicon photodiode(SPD) is divided into three pieces, a central SPD is made slightly smaller than a near infrared LED image in width, and the sides of the central SPD adjacent to other SPDs are formed polygonal. Near infrared rays incident on a subject from a camera body side are reflected from it and focused into a near infrared LED image 5 on SPDs 1, 2, and 3 arranged on a camera body separate from each other by the length of a base line. For instance, even if the near infrared LED image 5 is shifted and focused as a near infrared LED image 5a, the LED image is projected on the SPD 2 nearly half as much in light volume and the traveling distance of the near infrared LED image 5 on one of the SPDs becomes longer as compared with a conventional one, but the SPDs 1-3 can be lessened in area as a whole.

Title: Manufacture of geographic model
Inventor: IDEMOTO HIROKO
IPC: G09B29/12
Filed: 1988-12-26
Abstract: PURPOSE:To improve accuracy and to shorten a manufacture period by performing NC machining based upon data generated by processing information on contour lines by a computer. CONSTITUTION:A contour line data input means 1 inputs the contour of the contour line to the computer and also inputs altitude and the scale of a drawing. A means 2 which calculates an area to be cut and the altitude corresponding to it calculates the area of the same altitude by judging the altitude of an adjacent contour line and a mountain or valley. The process moves to a means 3 which calculates the depth of cutting from the top surface of the contour line to be cut through the means 2. The means 3 calculates the depth of a certain area from the top surface to be cut with the altitude of the area and the scale of a model to be manufactured when a rough rectangular parallelepiped material assuming the cutting is performed in the area of high altitude from inside. Then an NC data generating means 4 generates NC data from the depth of the area to be cut.
