Title: Carrying lift
Inventor: MARUYAMA KUNIO
IPC: B66F7/02
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To reasonably prevent the generation of vibration and noise due to the looseness of a chain while always eliminating the looseness of the chain by interposing an elastic body in the compressed condition between a ratchet and a top surface of a main body case, and always energizing the ratchet upward. SOLUTION: When drawing of a chain 8 exceeds 1/2 of a pitch of a claw 73a of a ratchet 73, the ratchet 8 is moved upward by the restoring force of a coil spring 81 by a distance at 1/2 or more of the pitch of the claw 73a. The other push claw 72 in the non-latch condition is moved downward in relation to the ratchet 73 by a distance at 1/2 or more of the pitch, and latched with a claw 73a of a following ratchet 73. At the same time, the push claw 72 in the latch condition is moved downward in relation to the ratchet 73 by a distance at 1/2 or more of the pitch of the claw 73a so as to release the latch. With this structure, drawing to be generated in the chain 8 is always absorbed so as to optimally maintain the tensile force of the chain.

Abstract: PROBLEM TO BE SOLVED: To arbitrate plural bus acquisition requests by flexibly setting up the bus using priority of plural devices connected to a bus in accordance with the bus using states of respective devices. SOLUTION: A priority decision part 103 receives a bus acquisition request signal 106 outputted from each of devices connected to a bus, extracts a counter value 110 indicating the bus acquisition expression frequency of respective devices from an arbitration counter part 101 and the priority data 111 of respective devices which are previously set up in a priority setting register part 102 and decides the priority of respective devices. The decision part 103 decides a device having the largest counter value as a target to which permission for using the bus is to be provided. Then the decision part 103 sends the arbitration ID of the decided device to a system bus 105 and outputs a counter reset signal 107 for resetting the counter value of the device acquiring the bus to the counter part 101.

IPC: B41J2/055
Filed: 1989-01-10
Abstract: PURPOSE:To prevent excessive forces from being exerted on vibrators during a manufacturing process and enhance the yield of manufacture by a construction wherein the outer profile is present in the inside of the outer profile of a base material. CONSTITUTION:Both a rigid base material 34 and a piezoelectric element plate 33 are rectangular, and each edge of the base material 34 being greater than or equal to the corresponding edge of the plate 33. Therefore, a base- piezoelectric element plate couple 39 obtained by bonding the above two members has an outer profile located on the outside of the outer profile of the piezoelectric element plate 33, whereby the periphery of the plate 33 is protected. Thus, in a polishing step or the like, excessive forces can be prevented from being exerted on the plate 33 to break or damage the plate 33. Though the piezoelectric element plate 33, with a 100-300mum thick piezoelectric material layer and a 50-200mum thick metallic layer, is brittle and susceptible to cracking, a strength necessary for protecting the plate 33 can be secured by forming the base material by use of a material about 0.8-5mm thick. The plate 33 can be protected by setting the outer profile thereof on the inner side of the outer profile of the base material by 0-0.2mm.

Title: Electrophotographic sensitive body
Inventor: KUBO TAKASHI
IPC: G03G5/00
Filed: 1986-01-13
Abstract: PURPOSE:To obtain the titled body capable of completely eliminating an interference fringe pattern appearing in an image formation and a black spot point appearing in a reversal development by specifying a surface roughness of the photosensitive layer. CONSTITUTION:The surface roughness of the photosensitive layer in the average roughness Rz of ten point measurements in the standard length of 2.5mm is >=1/2 optical wavelength of a light source which is used for forming an image. The optical phase in the photosensitive body, namely the phase difference formed at the interface thereof is preferably >=1/2 of the optical wavelength lambdaof the optical source to obtain a sufficient effect of preventing the interference. Strictly, the phase difference formed at the interface is somewhat affected with refractive index of an adjacent layer, etc., but is mostly determined by the geometrically component, namely the surface roughness of a boundary surface. Thus, the phase difference necessary for preventing the interference fringe is sufficient to be >=1/2 of the wavelength lambda of the optical source for forming the image, thereby preventing completely the interference.
