Publication number: 20240111236Abstract: An image forming apparatus includes a photosensitive drum, a charging member, a developing member, a transfer member, a brush, a drive unit, a control unit, and a memory. The charging member charges a surface of the photosensitive drum at a charging portion. The transfer member comes into contact with the photosensitive drum to form a transfer portion. The drive unit rotatably drive the photosensitive drum. The control unit controls the drive unit to perform an image forming operation. The memory stores information about the image forming operation. In a case where the image forming operation is performed and a non-image forming operation is performed after the image forming operation, the control unit performs control such that a switching operation for stopping the photosensitive drum after the photosensitive drum is driven and re-driving the photosensitive drum is performed a plurality of times based on the information about the image forming operation.Type: ApplicationFiled: September 22, 2023Publication date: April 4, 2024Inventors: SHINSUKE KOBAYASHI, TOSHIHIKO TAKAYAMA, KENSUKE UMEDA, AI SUZUKI

Patent number: 5453570Abstract: Disclosed is a karaoke authoring apparatus for mixing or authoring karaoke music data based on an electronic music sound source. The invention can analyze chronologically, in a sound reproduction block, the musical performance data expressed by a code such as MIDI code and has a pre-inserted event code, and will generate an interrupt in a timer circuit at a time interval based on the tempo instruction on the code. The invention can also acquire, as an individual file at the timing of the event code, an integrated value given by the timer circuit in accordance with the type of event, and combine and arrange these files in chronological order to calculate a time difference between consecutive event codes, for producing time data. The authored data allows color turning of the words of the music, page turning, presentation of the title of the music and a video image update which is performed accurately to the timing as planned, in synchronism with the musical performance.Type: GrantFiled: December 23, 1993Date of Patent: September 26, 1995Assignees: Ricoh Co., Ltd., Ricos Co., Ltd.Inventors: Toshihiko Umeda, Tomoyuki Tanaka, Masaaki Hamada, Yasuhiro Maruyama

Patent number: 5268904Abstract: In a method for controlling ISDN terminals connected to a passive bus conforming to an ISDN basic interface, the ISDN terminals being coupled to each other via a network, there are provided the following steps. A first step is to manage status of use of information channels in the passive bus by means of a communication server connected to the network. A second step is to send the communication server command data showing that the ISDN terminals will use the communication channels. A third step is to update management data showing the status of use of the information channels managed by the first step in response to receipt of the command data. A fourth step is to send updated management data showing the status of use of the information channels obtained after the command data is received to the ISDN terminals via the network.Type: GrantFiled: April 24, 1992Date of Patent: December 7, 1993Assignee: Ricoh Company, Ltd.Inventor: Toshihiko Umeda
