Patent JP-S6321676-A (JP)
Title: Developing method
Inventor: KUREMATSU KATSUMI
IPC: G03G15/06
Filed: 1986-07-15
Abstract: PURPOSE:To obtain sharp picture quality which has no edge effect by arranging a magnetic pole position in a development area, producing an alternating voltage based on a developing bias voltage, and expanding a developer layer until it contacts the surface of a latent image carrier and carrying out development. CONSTITUTION:A developer 4 is agitated by the A-directional rotation of a sleeve 2 and toner T is charged electrostatically by friction against magnetic particles and the sleeve 2 and conveyed in the direction A while stuck on the sleeve 2 along with the particles M. The toner T is carried to the development area in the form of a uniform-thickness layer by the magnetic force between a doctor blade 10 and a magnet roller 3. When the development is not performed, the developer layer and the surface of a photosensitive drum 1 are held in a noncontacting state. When the development is carried out, developing bias voltages are applied from a DC power source 5 and an AC power source 6, so an alternating magnetic field is produced in the development area. The developer in the development area while restrained by the magnetic force of a magnetic pole N1 is expanded between the sleeve and drum to contact the drum surface on the average with time, thereby performing the development.

Title: Diaphragm pump for liquid
Inventor: ICHIKAWA MINORU
IPC: F04B43/06
Filed: 1979-12-21
Abstract: PURPOSE:To make smooth a pulsating flow by making the path part of a diaphragm pump to be resilient. CONSTITUTION:Upon lifting of a diaphragm 1, corresponding flow is supplied into a pump chamber 2 while simultaneously the resilient wall 7b constituting a part of a path 7 is bent upwardly as shown by a dushed line by the negative pressure to reduce the volume in said path. Upon lowering of the diaphragm 1, the liquid is pushed out by the function of a suction valve 3 and a delivery valve 4, but the path part 7 at the suction side below said suction valve 3 will continuously suck the liquid by the recovery operation of the resilient wall 7b. Consequently when properly setting the flexure of the resilient wall 7b, the pump will continuously suck the liquid even during delivery. Similarly the resilient wall 8b of the path part 8 at the delivery side will bend downwardly during delivery as shown by a dushed line, to increase the volume in the path, and deliver the liquid continuously by the recovering force of the resilient wall 8b during delivery of pump. Consequently the pulsating flow is smoothened.

Title: Robot-joint-angle detector
Inventor: HOSOKAWA YORIO
IPC: B25J19/02
Filed: 1985-07-29
Abstract: PURPOSE:To make it possible to detect the joint angle of a robot in a broad angle range highly accurately without necessity for returning to the original point at the time of the recovery of power failure, by combining a highly accurate angle type and a broad angle digital type, as an absolute type rotation detector. CONSTITUTION:The rotary position of a motor M is detected by a resolver RE 4' for every rotation. The number of rotation of the RE 4' based on the rotation of a joint shaft 2 of a robot 1 at an original point is detected by an encoder 4 (gears G1-G4 and pulse generators PG1-PG4) as an integer value. The output pulses of the encoder 4 are serially transmitted to a join angle operator 7 through a transmission unit 19. The joint angle is computed from the counted value outputted from a latch circuit 5 and the output of the RE 4'. At the time of power failure, when the joint shaft 2 is rotated by an external force, the generators PG1-PG4 and the like are rotated. When the power source is recovered, the RE 4' indicates the present absolute rotary angle. The generators PG1-PG4 output the ON and OFF signals for the present position. Therefore, even if the joint angle is rotated during the power failure, the present angle is shown when the power failure is recovered. Thus returning to the original position at the time of the recovery of the power source is not required.

Title: Construction of concrete footing for building
Inventor: NAKAGAWA ATSUSHI
IPC: E02D27/01
Filed: 1989-06-28
Abstract: PURPOSE:To eliminate assembling and removal of forms and to simplify execution of work by installing forms made from corrugated metal plates that are put facing each other and being connected with connecting hardwares with erection bars arranged therein, and by making the forms integral with concrete that is placed therein. CONSTITUTION:Forms 2 made from corrugated metal plates are installed facing each other, being firmly fixed with connecting hardwares 9, on levelling concrete 5 that becomes a base board for excavated pit. Then erection bars 7 are arranged at the inside of the forms 2 and concrete is placed therein. As occasion demands, reinforcing frames 8 may be used for assembling. After curing of the concrete, the forms become integral with the concrete, resulting in functioning the same as the erection bars 7 that are arranged in the concrete. Leaking out of mortar that happens in the case of net forms can be prevented, making finishing work unnecessary. Thereby simplified execution of work with shortened term of work becomes feasible, eliminating works for assembling the forms and removing the same.
