Title: Measuring method for length of steel plate
Inventor: SATOU TAKASHI
IPC: G01B7/04
Filed: 1980-08-07
Abstract: PURPOSE:To measure length at high accuracy by measuring from the first maximum point of rolling pressure far from the bite-in end, and making the length to the final maximum point of rolling pressure far form bite-off end effective length. CONSTITUTION:When the boundary between the bite in end crop part and effective part is rolled by rolls 12, 14, a maximum point of rolling pressure is generated in driving and driven sides. The maximum point is detected by comparators 32, 32A. The detected signal far from the bite end is detected by an AND circuit 54. The signal is sent to a top crop length counter 48 and pulse number corresponding to bite end crop length is integrated and stored. Comparators 32, 32A makes count until bite off. When the bottom of the steel plate 10 comes out from the work roll, signals are sent to counters 38, 38A and 50, and pulse number corresponding to bite- off end crop length of driving and driven sides is integrated. On the other hand, pulse number corresponding to the length from the top to bottom end of the steel plate 10 is integrated in the total length counter 50 and sent to a steel plate length arithmetic unit 56. Thus, crop length and effective length of the steel plate 10 are calculated.

Title: Ink type wire dot printer head
Inventor: YAMASHITA OSAMU
IPC: B41J2/305
Filed: 1986-05-13
Abstract: PURPOSE:To constantly stabilize the behavior of a wire to inhibit the occurrence of ink-splash during printing, by disposing a cylindrical wire damper for regulating the vibration of the wire at the intermediate portion of the wire. CONSTITUTION:Current passing to a coil 16 leads a plunger 14 to be attracted by a yoke frame 17, a working plate 13 comes into impingement with a wire pin 12 to project a wire 10 in the direction of a platen 20, thus an ink from an ink adhesion guide 6 is transferred to a recording paper. Immediately after the ink is transferred, the current is turned OFF, which results in the return of the wire 10 by a return spring 11. Thus, the working plate 13 and the wire pin 12 again come into impingement with each other at an angle to the wire sliding direction; thus causing the occurrence of the vibration in the wire 10. This vibration energy is absorbed into a cylindrical wire damper 8 disposed at the intermediate portion of the wire, therefore, the wire 10 moves stably in the sliding direction thereof. In this manner, the generating of ink-splash can be prevented to obtain a stable printing quality.

Title: Method for detecting tail end of photoreceptor sheet in electro-photographic device
Inventor: OGAWA TETSUYA
IPC: G03G5/10
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To securely detect the tail end of a photoreceptor sheet without alteration of an optical sensor and a tail end mark by taking up the photoreceptor sheet at the time of the rotation of a photoreceptor drum in a direction opposite to that used during printing, and normally rotating the photoreceptor drum one or more times after taking it up. SOLUTION: In order to take up a photoreceptor sheet 3, a signal processing means 7 turns on a reverse rotation drive signal, thereby rotating a photoreceptor 1 reversely. Upon the completion of the take-up of the photoreceptor sheet 3, the signal processing means 7 turns off the reverse rotation drive signal to stop the reverse rotation of the photoreceptor 1. Immediately after the stop of the reverse rotation of the photoreceptor 1, the signal processing means 7 turns on a normal rotation drive signal to rotate the photoreceptor 1 normally. At the time, a value obtained by counting by a timer when the photoreceptor 1 makes one rotation is set T, and the measurement of an elapsed time T by the timer is monitored during the normal rotation.  Then, upon the measurement of the elapsed time T by the timer, the signal processing means 7 turns off the normal rotation drive signal to stop the normal rotation of the photoreceptor 1.

IPC: F04B17/06
Filed: 1988-05-04
Abstract: PURPOSE:To utilize wave energy to a maximum, by a method wherein check valves opened toward the down-stream side are respectively situated in a suction and a delivery passage, a guide and a cylinder, coupled to each other, are held on an inclination sea surface, and an inclination angle is regulatable. CONSTITUTION:A wave height amplified by a wave collecting device 11 enters through a wave intake port 4 to the interior of a caisson 1a, and is collided with a float 1 to press it toward the cylinder 2a side. This action moves a piston 2 and discharges sea water in the cylinder 2a through a delivery pipe 9. When water entering through an intake port 4 is moved backward from the interior of the caisson 1a, a float 1 and the piston 2 are slipped down under their own weights through the inclining caisson 1a and cylinder 2a and stopped. In this case, sea water is sucked through a suction pipe 8 to the cylinder 2a. In order to take in enough wave energy, the period of reciprocating movement of the piston is changed by changing a pump shaft center inclination angle thetato perform a water fed action in linkage with a wave period to improve efficiency.

Abstract: PURPOSE:To carry out an effective operation of an ammonia denitration device even in the low-load operating condition with a low exhaust temp., by furnishing a valve on a bypass exhaust passage, which is to lead exhaust gas to the ammo nia denitration device while bypassing the turbine concerned. CONSTITUTION:A turbine 7 and a blower 3 are rotated by exhaust gas, and suction gas with a high pressure is fed to the body 1 of a Diesel engine 1. The exhaust gas having passed the turbine 7 is led to an ammonia denitration device 6.
