Patent number: 11971682Abstract: A cartridge includes a first unit including a photosensitive member, and a second unit including a developer bearing member and a force receiving portion, the second unit being configured to be rotatable about a first axis to move with respect to the first unit between a first position and a second position. In a state where the first unit is in a same posture as when an image forming operation is performed, the second unit is disposed at the second position by its own weight. The developer bearing member is configured to be rotatable about a second axis. When seen in the direction of the first axis, a first distance between the force receiving portion and the second axis is smaller than a second distance between the first axis and the second axis and a third distance between the first axis and the force receiving portion.Type: GrantFiled: April 10, 2023Date of Patent: April 30, 2024Assignee: Canon Kabushiki KaishaInventors: Hideki Kakuta, Toshiaki Takeuchi, Yu Akiba, Shuichi Gofuku, Tomofumi Kawamura, Yusuke Atsu, Joji Goto

Patent number: 5459585Abstract: An apparatus for storing high definition image signals capable of processing high definition image signals and low definition image signals using the same apparatus. A storage medium is provided with an interface of low definition image signals. High definition image signals are compressed, transformed into a format according to the specifications of the interface of low definition image signals and are then stored in the storage medium. The compressed image signals taken out from the storage medium are subjected to the format reverse transform for expansion to restore the original high definition image signals. The format-transformed compressed high definition image signals and the compressed high definition image signals taken out from the storage medium are transmitted over a transmission medium via low definition image interface and are, as required, stored in the storage medium or put to other processings, and are then expanded to restore the original high definition image signals.Type: GrantFiled: August 17, 1993Date of Patent: October 17, 1995Assignee: Hitachi, Ltd.Inventors: Hitoaki Owashi, Toshiaki Kawamura, Yoshizumi Watatani, Katsuo Mohri, Michio Ozawa, Hideo Arai, Kyoichi Hosokawa, Kazutaka Naka, Fuzio Okamura

Patent number: 5161388Abstract: Electric expansion valves are provided midway along liquid-side pipes connected to indoor units. Electric flow control valves are provided midway along gas-side pipes connected to the indoor units. The indoor units detect air-conditioning loads, and a capability of a compressor is controlled in accordance with the sum of the air-conditioning loads. At the same time, the opening degrees of the flow control valves are controlled in accordance with the individual air-conditioning loads of the indoor units. In the heating operation mode, a high-pressure-side pressure of a refrigeration cycle is detected. When the high-pressure-side pressure becomes a preset value or more, an expansion valve and a flow control valve corresponding to an indoor unit whose operation is stopped are opened to predetermined opening degrees.Type: GrantFiled: October 25, 1991Date of Patent: November 10, 1992Assignee: Kabushiki Kaisha ToshibaInventors: Yoshinobu Fujita, Toshiaki Kawamura, Tooru Kubo, Mitsunobu Maezawa

Patent number: 4959778Abstract: An address space switching apparatus has a group of conventional registers capable of storing address information and a group of additional registers capable of storing address information longer than the address information stored by the group of conventional registers. The register length of the group of additional registers is not restricted by the length of the group of conventional registers and is selected to be of a magnitude sufficient to define a desired operand address space. Information items stored in the group of additional registers such as a base address and an index value associated with the extended address space are selected when an operand address is to be generated so as to be appropriately employed for the address computation, thereby supplying address information having a length sufficient for the extended address space.Type: GrantFiled: September 30, 1988Date of Patent: September 25, 1990Assignee: Hitachi, Ltd.Inventors: Hiroo Miyadera, Toru Ohtsuki, Toshiaki Kawamura

Patent number: 4507934Abstract: In a refrigerating system comprising a compressor, a condenser, a capillary tube, and an evaporator, there are provided a check valve on an inlet side of the condenser for preventing a reverse flow of refrigerant from the condenser to the compressor, and a differential valve connected to a delivery side of the condenser. One port of the differential valve is connected with the delivery side of the compressor, so that the differential valve interrupts the flow of the refrigerant from the condenser to the capillary tube upon interruption of the operation of the compressor thereby to improve the operational efficiency of the refrigerating system when the system is started again.Type: GrantFiled: May 11, 1983Date of Patent: April 2, 1985Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Tatsuo Tanaka, Toshiaki Kawamura
