Title: Cleaning device
Inventor: FURUICHI MASAYOSHI
IPC: G03G21/00
Filed: 1979-09-19
Abstract: PURPOSE:To make possible the maintenance of good cleaning performance by forming spiral grooves on a squeeze roller and carrying the toner on a blade plate further from the separating part steps of a photosensitive drum. CONSTITUTION:An elastic material roller 18 of sponge or the like which restores the original shape after it has been compressively deformed by a squeezing part 29 to squeeze out the absorbed excess developing solution expands rapidly upon passing a cleaning blade plate 22 and slides with the separating step parts of a drum 1, thus the remaining developing solution in the separating step parts is surely absorbed into the roller 18. Further, spiral grooves are provided to this roller 18 and the absorbed developing solution flows down from the roller 18 on the side opposite from the separating step parts, whereby the deposition of the toner in the separating step parts is prevented and the good cleaning performance may be maintained.

Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To stabilize the electrode formed on a photodetecting face of a solar cell element by forming an oxide film on the electrode surface. SOLUTION: A solar cell element 16 is set on a holder 2, a surface-treating gas produced by a structure treating gas producer 17 fed into a reactor chamber 19 to oxidize only the surface portion of 1×10<-3> -1×10<-1> μm thick of a photodetecting surface electrode, thereby forming an oxide film. If it is equal to or less than 1×10<-3> μm, its durability will be low, and if it is equal to or over 1×10<-1> μm, its solder wettability will be low. The surface treatment of the electrode forms a black thin film on the surface, and this stabilizes the electrode.

Title: Apparatus for testing bending fatigue of wire rope
Inventor: YANO TOSHIYUKI
IPC: G01N3/34
Filed: 1990-05-11
Abstract: PURPOSE:To perform fatigue tests at two portions simultaneously per rope by supporting both ends of a wire rope and reciprocating sheaves. CONSTITUTION:Rotation of a driving wheel 9 is converted by a coupling rod 8 into reciprocating motion of a movable mount 3 with sheaves 2a, 2b attached. A wire rope 1 rolled on the sheaves 2a, 2b is subjected to repetition of bending and stretching. Since the sheaves 2a, 2b freely rotate by themselves, they follow lateral reciprocating motion, and even when a direction is changed laterally, the wire rope 1 gives bending deformation without sliding on the sheaves 2a, 2b. Reciprocating speed of the sheaves 2a, 2b exhibits a since curve due to a crank mechanism so that smooth and rapid repetition can be done. In addition a severe test such as S-bending can be done by changing positions of the sheaves 2a, 2b. Since a part to be bent is a part to be in contact with a sheave, a single rope permits simultaneous fatigue tests on two portions.

Title: Braking control device for automated guided vehicle
Inventor: YOSHIDA KATSUHIKO
IPC: B60T8/18
Filed: 1994-06-03
Abstract: PURPOSE:To minimize and keep at a constant a braking distance by a command to brake by a mechanical braking device when a vehicle arrives at an end in a free running distance by making a combined deceleration of electrical and mechanical braking when the vehicle arrives at a braking start position. CONSTITUTION:When it is found by a distance recorder that a vehicle arrives at a deceleration start position, a relation between a distance and a speed to connect a target vehicle speed V1 at deceleration start and a free running speed V2 in a deceleration distance 6 is set in a braking control device. Based on a target deceleration curve 1, a deceleration upper limit allowable curve 2 and a deceleration lower limit allowable curve 3 to which upper and lower limit allowable values are added, respectively, are set up. Also a sufficient braking force cannot be obtained by a carrying load in electric braking, and a vehicle speed becomes faster than the vehicle speed of the target deceleration curve 1 and approaches the deceleration upper limit allowable curve 2. Then, when the vehicle speed reaches the same speed as that of the deceleration upper limit allowable curve 2, the braking control device acts a mechanical braking as well as electric braking. Thus the vehicle speed is decelerated remarkably to approach the deceleration lower limit allowable curve 3 so as to stop the action of the mechanical braking.

Abstract: PURPOSE:To take a high-accuracy measurement with simple constitution even when a surface to be measured is a rough surface by guiding reflected light from the surface to be measured to a self-pump type phase conjugate mirror(PCM) and reflecting the reflected light again by the surface to be measured. CONSTITUTION:The light emitted by a laser light source 1 is split by a beam splitter 2a into two. The reflected light which is passed through a frequency shifter 3 and reflected by a mirror 6, and then passes the frequency shifter 3 and the beam splitter 2a again is incident on a photodetector 7. The passing light, on the other hand, passes through a polarization beam splitter 21 and reaches a lambda/4 plate 5b to become circular polarized light, which is converged by an objective 8 and reflected by the surface 9 to be measured. Its reflected light passes through the objective 8 and lambda/4 plate 5b and is reflected by the polarization beam splitter 21 and branched by a beam splitter 2c into two. The reflected light is reflected by a PCM 20 and incident on the photodetector 7 reversely through the optical path. Then a phase difference meter 11 detects the phase difference between the interference output signal of the photodetector 7 and a reference signal and a computing element 17 processes it to measure the quantity of displacement of the surface 9 to be measured.
