Title: Corrosion-proof process for pipe-jointed section
Inventor: HATSUTORI SHINICHI
IPC: B29C65/48
Filed: 1979-04-05
Abstract: PURPOSE: To perform an efficient corrosion-proof work of a joint section and to ensure an improved corrosion-proof effect, by a method wherein a tube is constituted such that an outer layer consists of a heat contraction layer and an inner layer consists of a heat melt layer, and a joint section covered with the said tube is heated.  
     CONSTITUTION: A heat melt resin 2b (hot melt) is uniformly coated on one surface of a resin made sheet 2a having a given thickness and a heat contractibity. A two- layer sheet so formed is bent into a cylindrical shape, the both ends abutted on to each other being welded together to form a tube 1. An outer layer A consists of the sheet A and an inner layer B consists of the heat melt resin 2b. A pipe 8 and a pipe 9 are then welded together by a solder 6, the tube 1 being inserted onto the joint section 7 to cover it. Heating the tube 1 results in melting the inner layer B of the tube 1 and also in contracting the outer layer A. The contractive force causes the inner layer B (hot melt) to be completely closely adhered between the joint section 7 and the outer layer A of the tube 1.

Abstract: PURPOSE:To make construction simple and to make possible stable development by making the magnetic brush by the magnetic toner roughly equal to the moving speed of sleeve surface in a developing device which rotates a magnetic roll and a nonmagnetic sleeve in the same direction. CONSTITUTION:A magnetic roll 1 and a nonmagnetic cylindrical sleeve 2 are both rotated in the (x) direction; for example, 1 is at 1,000r.p.m., and 2 at less than about 50r.p.m. A layer of the magnetic toner of a constant thickness is formed to (x) direction on the sleeve surface from the leading end of an elastic member 4 contacting the sleeve 2 in its longitudinal direction by said member 4. On the other hand, a magnetic brush layer 32 which is transferred out in the (x) direction and can follow up the rotating magnetic field of the magnet roll is formed from the layer 31, and the layer 32 is in the direction opposite to the moving direction of the sleeve and its speed is roughly equal. When the layer 31 extends in the (x) direction and arrives at a nonmagnetic plate 34, the toner goes to the back of the plate 34, and the plate is moved in the (u) direction by the magnetic force to the toner, whereby the replenishment of the toner is stopped.

Title: Tape residual display device
Inventor: BABA TATSUJI
IPC: G11B27/17
Filed: 1992-02-27
Abstract: PURPOSE:To display a tape residual even when a tape thickness is not known. CONSTITUTION:The rotative cycles Ts and Tt of a supply side reel 11S and a winding side reel 11T are calculated by pulses outputted from reels FG12S and 12T at a microcomputer 15. The ratio ra of the area size of a tape T remaining on the supply side reel 11S is calculated against the sum of the area size of the tape T remaining on the supply side reel 11S and the area size of the tape T wound on the winding side reel 11T using the rotative cycles Ts and Tt. Then, a display control circuit 16 is controlled and the tape remaining quantity is displayed in a bar corresponding to the ratio ra. Also, the microcomputer 15 is provided with table showing the relation between the rotative cycle of the supply side reel 11S and remaining time and when the remaining quantity is more five minutes, the display control circuit 16 is controlled and the time of the tape remaining quantity is displayed. Thus, even when the tape thickness is not known, the tape remaining quantity is displayed well.

IPC: B61L23/14
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To preclude the necessity of holding an interval toward a preceding train to more than a required extent by calculating a speed restriction pattern for which the vehicle performance of a subsequent train is considered on the basis of the position and speed limit information of the preceding train loaded on the subsequent train and transmitted from a ground installation and making an operational control within the range of a speed limit pattern. SOLUTION: Information collected by new ATC ground stations 1a, 1b, 1c are converted to radio signals and transmitted to train operational devices 10a, 10b of trains 9a, 9b on the rail way. The train operational devices 10a, 10b that have received information from a new ATC ground station 1, catch this information as security signals, and calculate speed limiting signals (speed limiting pattern) for which the performance of own train itself is taken into account in the security part inside of train operational devices 10a, 10b. Then, on the basis of this speed limiting pattern, running control by means of automatic train operational function (ATO function) is practiced while holding a running interval distance to the preceding train. Next, information from train group 9a, 9b are transmitted to new ATC ground stations 1a, 1b, 1c through radio stations 2a, 2b, 2c.

Abstract: PROBLEM TO BE SOLVED: To execute copying without retrial of copying in the case of a memory-over state where image data of an original cannot be stored. SOLUTION: In the case that a setting switch of a memory residual quantity check is open (step S2), when a residual quantity check switch is closed in the step S1, a mean value of original sizes in all originals whose copying is reserved is calculated (step S3).

When the mean value of the original sizes is higher than the memory residual quantity in the step S4 and a forced release switch that tentatively stops the function by the judgement of the user is closed (step S5), the copying is accepted (step S2), and when the forced release switch is open, the copying is rejected (step S6) and the processing is terminated.
