Title: Automatic ticket examining machine
Inventor: TSUCHIYA SHINJI
IPC: G07B15/00
Filed: 1994-03-28
Abstract: PURPOSE:To handle noncontact ticket users and magnetic ticket users by operating a shutter so as to stop a magnetic ticket from being inserted into an insertion slot for a certain time once a sensor detects a user entering a ticket examination passage. CONSTITUTION:When the user enters the ticket examination passage without putting a noncontact ticket C2 close to a communication area (e) and one of sensors S1-S10 detects the entry, the shutter 6 is closed for the specific time. The closure time of the shutter 6 is set to a mean time wherein the user of the noncontact ticket C2 holds up the noncontact ticket C2 to the communication area (e). Thus, the insertion slot 1 is closed by the shutter 6 until a series of automatic ticket examining processes using the noncontact ticket C2 end, so a following user of a magnetic ticket C1 can not inserts the magnetic ticket C1 into the insertion slot 1. Consequently, the trouble that the magnetic ticket C1 of the following user automatically opens the gate for the precedent user is effectively prevented.

Title: Harvester for root crops
Inventor: YANO NORIHIRO
IPC: A01D25/00
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a harvester for root crops hardly raising the soil of a field upward by a colter of a digging device when digging and harvesting carrots in the field, hardly scraping in the soil by the tip part of a nipping and conveying belt even if the carrot is pulled out, excellent in pulling-out properties, and having a long-life nipping and conveying belt. SOLUTION: This harvester for root crops has a colter 27b of a digging device 5 constituted so that the angle θ between a ridge surface of a field and the colter 27b may form the right angle or an obtuse angle tilted forward. As a result, the soil is not scraped in by the tip part of a nipping and conveying belt 28a for pulling up the carrot A, because the soil at both sides of the carrot A is cut and divided, and dug by the colter 27b, but the colter 27b acts so as to push down the dug soil, and does not act so as to raise the soil. Further, the pulling up properties of the nipping and conveying belt 28a is hardly decreased, the damage of a pulling-up and conveying device 28 is decreased, and its life is elongated because the soil is not attached to the nipping and conveying belt 28a.

Abstract: PURPOSE: To make it possible to establish the relation between the rotating angle position of a video head and the position detection signal from a position detector by forming a delay signal as a data signal and storing this signal as a dynamic working value in a non-volatile memory. CONSTITUTION: This video tape recorder is composed of a head drum device 1, a head drum control circuit 2, a head switch 3, a video signal processing section 4 of the stage behind this switch, a test circuit 5 and the non-volatile memory 6. In such a case, the data signal is used as the delay signal. The data value of the data signal corresponds to the delay quantity to be set. The data signal is stored as the dynamic working value of the video tape recorder in the non-volatile memory 6. The delay signal is determined by a test circuit 5 disposed in the tape recorder by calculation or comparison processing. As a result, the setting of the phase depends upon the accuracy of the test circuit 5 and the test circuit 5 obtains the set accuracy with the accuracy in the period shorter than half a line period.

Title: Transfer device of slurry pump
Inventor: FUKUDA SHIYOUZOU
IPC: F16K11/02
Filed: 1981-05-28
Abstract: PURPOSE:To prevent an oscillation face from being abraded and extend the life of an osicllation plate by fitting a seal ring so as to be rotated around the circumference at one end of an oscillation pipe in relation with transfer actions of the oscillation pipe and by forcing the seal ring to rotate by use of oscillations of the oscillation plate. CONSTITUTION:When an oscillation pipe 14 fitted to one end of a cylinder 11 provided in parallel is swayed, the teeth 18a of a seal ring 18 is latched by a holdfast 21 and the seal ring 18 is rotated by one pitch of the teeth 18a. When the oscillation pipe 14 is swayed in the opposite direction, the holdfast 21 is merely raised upward along a slope of the teeth 18a on the seal ring 18, and as a result, the seal ring 18 is rotated by one pitch of the teeth 18a during one reciprocation of the oscillation pipe 14. Thereby, partial abrasion of the sliding face is prevented, and the life of a sliding plate 19 can be largely extended. Furthermore, any blended concrete of poor concrete ratio generated by the increase of gaps between the sliding plate 19 and the seal ring 18 or water for water washing can be pressure fed.

CONSTITUTION:A separation membrane made of ceramics is produced by charging superfine ceramic particles 1b produced in a CVD reaction pipe 2 between a creeping discharge electrode 5 and the electrodes 6 for migrating the particles and electrostatically sticking the superfine ceramic particles on the surface of the sintered porous bodies 14 and intactly heating and sintering the produced porous build-up layer 15 of superfine particles. By this method, since the diameter of the superfine particles is uniform, the membrane thickness and the diameter of extremely fine pore of the separation membrane made of ceramics after sintering are easily controlled and the membrane having fine pores of tentseveral Angstrom can be produced. Further as the superfine particles, all substances such as alumina, titanium oxide, silicon nitride and silica can be almost utilized.

Filed: 1982-05-14
Abstract: PURPOSE:To increase the resolution, by moving a moving exposure optical system forming an original image on a screen photoreceptor consisting of an endless belt in a speed slightly slower than that of the screen photoreceptor. CONSTITUTION:An endless belt screen photoreceptor 10 moving toward the arrow B is charged with a corona charger 14 and an image of an original 2 is formed on the photoreceptor 10 with a moving exposure optical system 3. This electrostatic latent image is formed on an insulation belt 18 with a modulated corona charger by taking the image of the original 2 as the latent image, developed with a developing roller 24 and copied and fixed on a copy paper supplied from a copy cassette with a corona charger for transposition 30. Since the movement of an exposure optical system is smaller than the speed of the screen photoreceptor, the mesh value of the photoreceptor toward the moving direction is larger than that to the broadwise direction, allowing to increase the resolution toward the moving direction.
