Title: Treatment work for head of in-site concrete pile
Inventor: MAEDA ATSUMI
IPC: E02D5/34
Filed: 1985-08-27
Abstract: PURPOSE:To make the treatment work of pile head easier by a method in which a bucket is attached to the inside pile head portion of a reinforcing bar cage, extra-banking concrete is poured from the hole of the bottom plate of the bucket into the bucket, and when the concrete becomes semi-hardened, the bucket is lifted up to discharge the concrete.

Title: Center clamp bushing
Inventor: MINAMITANI YASUO
IPC: H01B17/26
Filed: 1989-07-21
Abstract: PURPOSE:To obtain a center clamp bushing whose variation in center clamp power is small, and whose assembly is easy with a good sealing property, and whose inside cooling ability is good by dividing a center conductor into two in a shaft direction, and by elastically connecting them together by an elastic body. CONSTITUTION:A center conductor 1 in an expansion chamber 6 is divided into two parts, A and B in a shaft direction. Each parts thereof is elastically connected to one another by an aggregate of an elastic body 11 such as a spring and an elastic connector 13. By the working of the elastic body 11, an equivalent spring constant of the center conductor 1 can be decreased, whereby variation in center clamp power due to thermal expansion can be reduced. Stability in sealing and the mechanical strength of the bushing can thus be maintained, and the structure is simplified for easy assembly. Since the positioning of the spring is not regulated, the upper end, etc., of the center conductor can be soaked in an insulating oil and can be cooled, whereby conductivity can be improved. For a lead elevating type center clamp bushing, the center conductor is replaced with a center pipe, and the same effect can be obtained.

Title: Fully automated washing machine
Inventor: SANO SOICHI
IPC: D06F33/02
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To shorten operating time by estimating the draining condition of fully automated washing from draining time between tow predetermined levels of water in a draining stroke if the amount of clothing is large or if the amount of clothing is large and the quality of cloth is such that it is likely to bear water, and setting the intermittent operation control time of a dewatering stroke to be short if the draining condition is good. SOLUTION: When detection of the amount of cloth or both the amount and quality of cloth indicates that the amount of clothing is large or that the amount of clothing is large and that the quality of the cloth is such that it is likely t bear water, the draining condition of fully automated washing is estimated from draining time between two predetermined levels of water during a draining stroke, and if the draining condition is good the intermittent operation control time of a dewatering stroke is set to a short one. When the draining condition of the fully automated washing is good irrespective of the amount and quality of clothing, the intermittent dewatering time of the dewatering stroke shortens and therefore the electric energy consumed ca be reduced because of reductions in operating time and motor current-carrying time.

The color copying machine 1 decides whether or not copying is possible by each personalized setting, when it is possible, copying is performed and, when it is impossible without any sheet of paper of a corresponding type or kind, error display is performed. Thus, the operability is improved and a great amount of setting data and image data can be stored.

Title: Liquid level detector
Inventor: TAKATORI HIROAKI
IPC: G01F23/14
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To stably and accurately detect a liquid level becoming a predetermined level by switching proximity to or separation from a reed switch by a magnet mounted at a snap action mechanism in response to a snap action. SOLUTION: This liquid level detector 11 switches a proximity to or a separation from a reed switch 36 fixed to an operation chamber 26 by a magnet 37 mounted at a snap action mechanism 30 in response to a snap action. Accordingly, a diaphragm 20 is displaced according to a pressure change of a pressure chamber 25 due to a liquid level change in a tank. When an operating shaft 28 is moved at a set value or more, the mechanism 30 is snapped, and the magnet 37 is switched from the proximity to the separation from the switch 36. Thus, when the level becomes a predetermined level, the magnet 37 is set to be switched so that the level can be sensed.  In this case, since the switch 36 is changed in its operation by a magnetic field change of the magnet 37, the detector 11 can accurately detect the level stably to the level change due to a fluctuation of the tank without continuity fault due to dust or the like.

Title: Position measuring instrument
Inventor: TABATA MITSUO
IPC: G01B11/00
Filed: 1985-08-30
Abstract: PURPOSE:To measure the position of a measurement surface precisely by controlling electric power supplied to a light irradiation part corresponding to the quantity of reflected light in addition to the standardization of the output of a detector by a divider, and canceling variation in the quantity of reflected light even when the reflection factor of a surface to be measured is different greatly. CONSTITUTION:Reflected light 59 from the surface of a sample 30 is image-formed on the photodetection surface of a semiconductor position detector 53 which uses known lateral light effect. The detector 53 outputs unbalanced signal from its couple of output terminals on the basis of the displacement of the irradiation position of a light spot on a thin resistive film. The detection signals are processed by an adder 54, a subtracter 55, a divider 56, etc., and inputted to a position measuring circuit 58 to obtain an output corresponding to the position of the surface of the sample. The output of the adder 54 is compared 57 with a set value and a light source driving circuit 47 is controlled 48 to adjust the electric power, thereby controlling the quantity of light of a light source 41. Consequently, the output of the adder 54 reduces the input dynamic range of the divider 56 into a constant range to perform arithmetic with high precision and even if the reflection factor of the sample surface is different greatly, the position of the sample surface is measured without any deterioration in precision.
