Patent number: 6361685Abstract: The present invention relates to a method and an apparatus for fermentation of cattle dung or like organic waste material containing high percentage of water. In a method of accommodating a treating object material consisting of an organic waste material containing a predetermined quantity of water in a fermentor for fermentation, a method of the present invention comprises the step of granulating the treating object material in a nodular-shape before being accommodated in the fermentor for fermentation with the supply of warm air in starting of fermentation through manually communicating ventilation spaces formed between the surfaces of the adjacent granules of the treating object material. The percentage of water content in the treating object material before being granulated is controlled until a percentage of water content enough to permit granulation and aerobic fermentation is reached.Type: GrantFiled: July 14, 2000Date of Patent: March 26, 2002Assignee: Kabushiki Kaisha Dai-Ichi ConsultantInventor: Takahisa Shimada

Patent number: 5798625Abstract: A dc motor wherein a driving force thereof can be used effectively with a simple and compact mechanical construction and a motor controlling system which can control such a dc motor to be driven efficiently. The motor comprises at least two coils, and change-over means for changing electric connection of the coils to change over the motor, when power is selectively supplied to the coils, between a first mode in which the torque produced is relatively high and the rotational frequency is relatively low and a second mode in which the torque is relatively low and the rotational frequency is relatively high. The motor controlling system includes selecting means for automatically selecting one of the first and second modes to control the change-over means in response to a given condition of the motor.Type: GrantFiled: July 31, 1995Date of Patent: August 25, 1998Assignee: Minolta Camera Co., Ltd.Inventors: Junichi Tanii, Hiroshi Ootsuka, Toshihiko Taniguchi, Takahisa Shimada, Sadafusa Tsuji

Patent number: 5483310Abstract: A film cartridge includes a rewinding shaft for rewinding a film, a case having a film exit/entrance and accommodating the film rewound by the shaft therearound in a light-intercepted condition, and a locking mechanism for locking the leading portion of the film in the film exit/entrance in the vicinity thereof, so that the film does not get out of the cartridge more than a predetermined amount or get out of the exit/entrance carelessly. The shaft or a film feeding-out member in the cartridge is set in a predetermined position, so that the shaft or the member is immediately and smoothly connected with a corresponding member of a camera for accommodating the cartridge. A camera accommodates the cartridge to take the advantage.Type: GrantFiled: December 28, 1994Date of Patent: January 9, 1996Assignee: Minolta Camera Kabushiki KaishaInventors: Junichi Tanii, Takahisa Shimada, Masaaki Chikasaki, Sadafusa Tsuji, Yoshinobu Kudo
