Title: Sheet material conveying and stacking device
Inventor: KITAHARA YOSHIHIKO
IPC: B65H39/11
Filed: 1994-12-14
Abstract: PURPOSE: To improve the function and reliability of this device by providing an air blow-off part for jetting air so as to deliver a sheet material which is fed to a sheet material stacking means to the top surface of a sheet material precedingly fed to and received by the sheet material stacking means under a floating condition. CONSTITUTION: A sheet material S on the conveying endless belt 22 of a sheet material conveying unit 16 is suction-held by the operation of a suction fan 22 for stable conveyance. A part of exhaust discharged from the air blowing-off port of the suction fan 22 passes through a fan duct 22A and is blown off from an air blowing-off part 22B on the front side of the sheet material kicking-out part A of a conveying unit 16. As a result, when the sheet material S conveyed by the sheet material conveying unit 16 is delivered to a sorting bin N from the kicking-out part A, blown-off air (c) is brought into contact with the back surface of the sheet material S being delivered, so that the sheet material S is delivered onto the sorting bin N in a non-contact condition with the top surface of the stacked sheet material Sa.

Title: Optical disk recording and reproducing device
Inventor: KARITA YOSHIHIRO
IPC: G11B20/10
Filed: 1993-12-27
Abstract: PURPOSE:To successively record and reproduce plural zones by providing a couple of PLL oscillators, and preparing a data clock for a next zone during the operation of one oscillator and switching the oscillator. CONSTITUTION:The synchronous signal from an optical disk 1 is inputted from a synchronous signal extracting circuit 10 to the 1st PLL oscillator 14 to generate a data clock, which is sent to a data demodulating circuit 8 and a data modulating circuit 9. The data clock is sent to a frequency divider 11 to generate the synchronous signal for a next zone with a proper frequency division ratio, and the signal is inputted to the 2nd PLL oscillator 15 to prepare a data clock after zone changing. When the recording or reproduction of the current zone ends and the sector mark of the next zone is detected, switches 12, 13, and 16 are switched over. A data clock for recording and reproduction matches the reproduction speed of a new zone and the recording and reproduction can be performed from the starting sector. At the same time, the oscillator 14 and 15 are reset, and the data clock generated by the oscillator 15 is made to pass the oscillator 14 to prepare the data clock for the next zone.

Title: Water leakage detecting method for pipe
Inventor: TAKEHARA YUKIHISA
IPC: F17D5/02
Filed: 1990-11-28
Abstract: PURPOSE:To correctly detect a leaking pipe at a high speed without causing corrosion on the pipe by putting an iron sulfate or phosphoric acid chemical in the pipe as a tracer, and analyzing the water quality of the leaked water. CONSTITUTION:When water leakage 13 occurs on either a sea water pipe 10, a process discharge pipe 11 or an industrial water pipe 12, an iron sulfate solution 16 is put in the intake section 15 of the water feed pump 14 of the pipe 10. S, Fe components in the leaked water 13 are analyzed with anatomic absorption photometer each time a preset period elapses. If the S, Fe concentration indicates a high value after a preset period elapses, it is judged that water leakage occurs on the pipe 10. The presence of water leakage is detected on the pipes 11, 12 by the same method. Iron sulfate is a corrosion-proof chemical, and no corrosion is caused on the pipe. The leaking pipe can be simply detected at a high speed.

Title: Light source controller for image input device or the like
Inventor: TANAHASHI MARIKO
IPC: H04N1/04
Filed: 1990-11-29
Abstract: PURPOSE:To decrease the fluctuations in a light emission quantity by the tube surface temp. of a light source by setting the target tube surface temp. of the light source at a temp. at which the differential coefft. to the temp. of light emission brightness is min. CONSTITUTION:A temp. setting means sets the target temp. of the tube surface at the temp. at which the differential coefft. to the temp. of the light emission brightness of a fluorescent lamp is min. Namely, while the brightness changes just by (x) in a range of A deg.+ or -alpha if the target tube surface temp. is set at A deg. in Fig., there is a change of (y) (y>x) at other temp. (for example, B deg.+ or -alpha) and the A deg. is eventually the temp. at which the change is least. The A deg. is the position where the differential coefft. is zero and the target tube surface temp. is set at this position. The change in the light emission brightness by a change in the tube surface temp. of the fluorescent lamp is minimized in this way.

IPC: H01C10/00
Filed: 1987-12-28
Abstract: PURPOSE:To eliminate the friction between the bent section of a coil spring and the adjacent spring section and thereby to prevent the bent section from breaking, by providing on a rotor with a hole section cut obliquely downward at an acute angle to the direction of returning of rotor due to the force of a coil spring, and by inserting into the hole section the bent section of the coil spring formed in the same direction as that of the hole section. CONSTITUTION:Through a rotor 3 connected with the lower end of an shaft 1, a hole section 10 is formed obliquely downward at an acute angle to the rotor 3 returning direction (in the direction D shown by the arrow) by the force of a coil spring 8, and the bent section 8a of the coil spring 8 formed in the same direction as that of the hole section 10, is inserted into the hole section 10. When the repulsive force of the coil spring 8 works on the joint section of the bent section 8a and the hole section 10 in the case that a lever 4 is rotated by an external force, the bent section 8a receives force in the direction (in the direction E shown by the arrow) where the bent section 8a is inserted into the hole section 10, and the bent section 8a does not come off the hole section 10. This eliminates the partial friction between the bent section 8a and its adjacent spring section 8b too, and enables preventing the breakage of the bent section 8a.
