Title: Bag tear-opening device
Inventor: BAYER MANFRED
IPC: B65B69/00
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent continuos object hard tear from being caught in the gap between transporting elements to be wound up by arranging a plurality of shut-off and scraping pieces for covering laterally a part of the other transporting element relative to the movement direction to one transporting element of adjacent transporting elements. SOLUTION: A small gap 24 is interposed between the adjacent strips 7, 8 of a strip drum from the reason of manufacturing technique. A plurality of shut-off and scraping pieces 25 are disposed along the strips 7, 8 at mutual intervals. The scraping pieces 25 partially get covered in lateral direction on the strips 7, 8 adjacent every time to the other strips drum at right angles to the movement direction 27 of the strip drum. Thus, even if the continuous object hard to tear is wound up by the strips 7, 8 of a tear opening drum 4 and is apt to be drawn into a gap between the strip drums, it is prevented from being drawn in by the shut-off and scraping pieces 25.

Title: Spark plug cap
Inventor: KOSAKA KENICHI
IPC: H01T13/06
Filed: 1994-06-27
Abstract: PURPOSE:To prevent penetration of water and the like to a spark plug fixing hole by communicatively installing an atmospheric pressure adjusting chamber in an air vent communicating with a spark plug fixing hole to isolate the air vent from the outside air. CONSTITUTION:A thin rubber bellows-shaped atmospheric pressure adjusting chamber 21 is communicatively installed in an air vent 20 to absorb the atmospheric pressure change in a spark plug fixing hole 5. A spark plug cap 10 stores air expanded within the fixing hole 5 by self heating in starting of an engine through the air vent 20. When the atmospheric pressure within the fixing hole 5 drops by cooling after stop of the engine, air stored in the adjusting chamber 21 returns to the fixing hole 5. The air vent 20 and the fixing hole 5 are completely isolated from the outside, and penetration of water and the like is prevented. Since the adjusting chamber 21 is integrally formed with a head cover 6 and the fixing hole 5 is sealed so as to communicate only with the air vent 20, even in washing with high pressure water, water penetration from the air vent 20 to the fixing hole 5 is prevented. A contact part 9 of the cover 6 is closely fit to a projecting wall 8, and a closely contact part 7 is brought into contact with the inner wall of the fixing hole 5 by pressure.

Filed: 1984-07-13
Abstract: PURPOSE:To shorten the waiting time up to a set temperature of a laser diode when a primary power supply of a recorder is turned on again, by stopping and closing a fan and an opening respectively with a delay after turning off the primary power supply. CONSTITUTION:A recorder uses a laser diode unit as a light source for scan, and a temperature controller of this recorder is provided with a temperature detector 32, a comparator 33, a memory 34 and a controller 35. Then the temperature controller drives and controls a fan and a cover open/close device. The detector 32 measures the ambient temperatures and delivers the temperature information in real time to the comparator 33. While a comparison temperature for delay is stored in the memory 34 and also delivered to the comparator 33. In case said comparison temperature t deg.C is lower than an ambient temperature detected by the detector 32, the fan is driven continuously until the ambient temperature reaches t deg.C even after a primary power supply is turned off.

Filed: 1988-06-15
Abstract: PURPOSE:To indicate the availability of key operation corresponding to the degree of skillfulness of an operator by varying the discoloration time of a key which is touched according to the time intervals of a key touch. CONSTITUTION:When the operator depresses a key with a '1' display on a touch panel successively to a key with a 'C' display, a control part 13 finds the difference in key depression time between last key depression time which is set in a register 14 and the current key depression time of the '1' key. Then the time (t) which is the interval of key depression is found and then the control part 13 sets the current '1' key depression time in the register 14. The control part 13 finds the discoloration time when the key depression interval time is the time (t) by using a table (stored on the memory in the control part 13). When t2<t<t3, n2 is found as the discoloration time. Consequently, the control part 13 puts a screen display back in the original state after the '1' display key discolors for the time n2, so the key operation is performed according to the degree of skillfulness of the operator.
