Title: Photoreceptor driving device
Inventor: KAWABE MASAHIRO
IPC: G03G21/00
Filed: 1993-09-30
Abstract: PURPOSE:To prevent toner from entering between a photoreceptor and a driving roller by providing a cleaning means cleaning the inside of the photoreceptor in a photoreceptor frame. CONSTITUTION:This device is equipped with a spring 15 being a tension means installed between a photoreceptor arm 14 whose one end is turnably set on the photoreceptor frame 18 and whose other end is provided with a tension roller 3 and the frame 18, and a brush 20 forming the cleaning means scraping toner and paper powder, etc., in contact with the inner peripheral surface of the photoreceptor 4, and further preventing the toner and the paper powder, etc., entering the peripheral surface of the driving roller. In such a case, the cleaning means is disposed so as to cover the driving roller 1 inside the photoreceptor 4, and positioned so that the toner and the paper powder, etc., adhering to the inner peripheral surface of the photoreceptor 4 are not scattered to go around on the peripheral surface of the roller 1. The adhesion of the scattered toner or the paper powder, etc., from a developing roller and a cleaning blade is also prevented.

Title: Device and method for monitoring intrusion
Inventor: SAKAI YASUO
IPC: G08B13/196
Filed: 1994-09-13
Abstract: PURPOSE: To exactly detect only the intruder by detecting the intruder without using any sensor by judging the presence/absence of the intruder based on a transition pattern in the state changes of plural detection blocks. CONSTITUTION: A judge output control part 38 observes the conditions of the state changes of respective blocks stored in a third memory area 28 for prescribed time and decides the transition pattern in those state changes. Corresponding to the decided transition pattern, the presence/absence of the intruder and the presence/absence of any visitor are decided. When the presence of the intruder is judged, the judge output control part 38 activates a monitoring device 44 by transmitting a monitor ON signal and the image of the suspected person photographed by a CCD camera 10 is displayed from the monitor screen of the monitoring device 44. Besides, the judge output control part 38 activates a warning device 40 and an alarm tone is generated from this warning device 40.  On the other hand, when the presence of any visitor is judged, the judge output control part 38 next activates a calling device 42 and an indoor calling chime is rung.

IPC: F04B1/20
Filed: 1986-10-15
Abstract: PURPOSE:To ensure a good neutral characteristic, by making a thrust plate provided in a cam plate rotatable in free direction with respect to the cam plate. CONSTITUTION:An input shaft 7 for a cylinder block 6 is penetrated through through-holes 14 formed through a thrust plate 17 and a cam plate 12 and projected ahead of the cam plate 12.

Title: Method and equipment for reversible cold rolling
Inventor: KAJIWARA TOSHIYUKI
IPC: B65H16/10
Filed: 1986-10-15
Abstract: PURPOSE:To decrease the waste of scrap generation by constituting at least one reel of one unit each of the reels on the inlet side and outlet side of a rolling mill in such a manner that the reel can move at the distance between a reel drum and the rolling mill. CONSTITUTION:A stock 3 which is un-coiled from a stock un-coiling drum 25 is fed through a delivery roller 26 and a retainer 21 into the rolling mill 22. The stock contacts an upper work roll 6 and a lower work roll 7 in the rolling mill 22 and is thereby rolled. The rolled strip is taken up via an outlet side deflector roller 9 on the outlet side reel drum 24. The outlet side reel drum 24 and the inlet side reel drum 23 are positioned to the front ends of turning arms 27, 28, by which the distance from the rolling mill 22 can be changed. The length of the unrolled part existing between the drums 23, 24 and the rolling mill 22 is, therefore, shortened, and the waste of the scrap generation is decreased.

Filed: 1994-10-11
Abstract: PURPOSE: To reduce fatigue failure of a liner provided inside of a header pipe by providing drain boards of a specified height between water injection holes of a spray nozzle pipe and an inner wall of the header pipe. CONSTITUTION: Drain boards 6 having a height of 0. 5 or more times a diameter of a spray nozzle pipe 3 are provided between water injection holes 8 of the spray nozzle pipe 3 and an inner wall of a header pipe 1. In the case where a liner 5 is provided inside of the header pipe 1, the drain boards 6 are provided between the water injection holes 8 and an inner wall of the liner 5. Further, a cross section of the spray nozzle pipe 3 projected in a flow direction of vapor 2 is limited to 0.4 or less times an inner cross sectional area inside the liner 5. With such arrangement, flowing of spray water 4 on a side of the spray nozzle pipe 3 facing downstream in the flow direction of the vapor 2 is shut off to be again scattered in the vapor 2, thereby enabling preventing the spray water 4 from entering the liner 5.  Accordingly, evaporation of the spray water 4 is promoted, and generation of thermal stress on the liner 5 clue to drift of water flow can be prevented. Also, it is possible to reduce fatigue failure of the liner 5.

Title: Side air bag device for vehicle
Inventor: MIYAHARA TAKEHIKO
IPC: B60R21/217
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To protect an occupant's head even without forming a rib on a pillar garnish. SOLUTION: In this side air bag device, an easily deformable pipe member 12 is disposed in a position corresponding to an occupant's head H. Thereby, even if the occupant's head H strikes a pillar garnish 15, the deformation of the pipe member 12 absorbs a shock energy applied to the occupant's head H to protect the head H. Accordingly, it is not necessary to form a rib on the rear face of the pillar garnish 15 like before, and a clearance between the pipe member 12 and the pillar garnish 15 can be reduced to enlarge an in-cabin space.

Title: Microwave sample fixation apparatus
Inventor: MORI CHIHARU
IPC: G01N1/28
Filed: 1994-09-05
Abstract: PURPOSE: To provide a microwave sample fixation apparatus by which a sample can be fixed with high quality and in a short time by a method wherein a microwave irradiation operation is added to a chemical fixation treatment. CONSTITUTION: A fixation bottle 4 in which a sample has been immersed in a fixation liquid 5 is arranged and installed in a cooling liquid 6, and microwaves are sent out to the sample from the output face of an applicator 3 which is arranged so as to face the sample. On the basis of an irradiation characteristic, a part near the output face of the applicator 3 is irradiated locally, and the fixation of the sample is promoted. At this time, microwave energy which has been absorbed in the fixation liquid 5 is changed into thermal energy so as to raise the temperature of the fixation liquid 5. The raised temperature is discharged to the cooling liquid 6 through the fixation bottle 4, and the temperature rise of the fixation liquid 5 is thermally balanced to a certain extent.  The irradiation condition of a microwave generation part 1 and the discharge capability of heat from the fixation liquid 5 are set in such a way that the thermal balance does not exceed the upper-limit temperature of the fixation of the sample. In addition, when the cooling liquid 6 is cooled forcibly by an electronic cooling part 10, microwave irradiation energy is increased further, and the sample can be fixed quickly and with high quality.

Title: Form clamping apparatus
Inventor: TOYODA MINORU
IPC: B28B7/00
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To simply respond to a case wherein concrete products different in width are to be produced by moving the fixed position of a form by enabling the selection of a clamped state and released state of the form by rotating a pressure cam by a rotary means. SOLUTION: A pressure cam 6 is a disc member and flange parts 7 having a diameter larger than that of the disc member are integrally formed on both sides of the disc member. A shaft 8 being a rotary means is fixed to the pressure cam 6 and mounted on the support piece 13 fixed to a base 15 in a freely rotatable manner. The center X of the shaft and the center Y of the disc member are made eccentric and, since the disc member is rotated centering around the center X of the shaft, the disc member comes into contact with a clamping lever 5 to press the same downward or the disc member is separated from the clamping lever 5 or acts as a cam. Therefore, the clamping and releasing work of the form of a panel-shaped concrete product can be efficiently performed and, since the clamping part of the form can be moved, this clamping device is used in forms of products having various sizes.
