Patent number: 6503550Abstract: A method for controlling the temperature of edible dough to efficiently and promptly control the dough temperature without adversely affecting the working environments, to operate them for a long period of time, and to apply them to any type of a mixer. The method for controlling the temperature of the edible dough during a kneading step includes a step of kneading the edible dough. During the kneading of the edible dough, the method includes a step of introducing a predetermined amount of gas having a predetermined temperature and a predetermined humidity into a mixer. It is preferable that the gas for controlling the temperature of the edible dough has been prepared and kept in advance at a predetermined temperature and humidity, and is then introduced into the mixer on demand. It is also preferable that the gas is circulated and re-used without being discharged out of a system in which the mixer operates.Type: GrantFiled: October 23, 2000Date of Patent: January 7, 2003Assignee: Ajinomoto Co., Inc.Inventors: Takao Suganuma, Yasunobu Hasegawa, Kiyoshi Usami, Akisato Tsukada, Takahiro Kuratani, Kazutaka Takahashi

Patent number: 5983937Abstract: First to third openings are formed stepwise in a rotor side wall portion of a flow control valve disposed in a hot water circuit. Third positions (a) and (b) are established between a first position in which a first communication passage for communication between inlet and outlet pipes of the flow control valve is fully closed and a second position in which the first communication passage is fully opened. A duty control is performed so that the rotor reciprocates repeatedly among the above four positions. In this way, in the flow control valve for controlling the amount of the fluid flowing in the fluid passage, the valve colliding noise, the water hammer noise, and the temperature variation in the heating heat exchanger can be reduced.Type: GrantFiled: February 4, 1997Date of Patent: November 16, 1999Assignee: Denso CorporationInventors: Masamichi Makihara, Kiyoshi Usami, Yoshio Miyata

Patent number: 5408841Abstract: A compressor is prevented from the problem of seizure at start-up even when return of lubricant to the compressor is delayed. In such a refrigerant cycle, a bypass passage bypasses an expansion member and an evaporator. The bypass passage opens for a predetermined time when the compressor starts. The predetermined time is dependent upon external temperature, the compressor speed, compressor capacity, etc.Type: GrantFiled: March 9, 1994Date of Patent: April 25, 1995Assignee: Nippondenso Co., Ltd.Inventors: Takashi Fujiwara, Kiyoshi Usami, Yasuyuki Nishi, Shigeo Numazawa, Hiroshi Kishita

Patent number: 4449622Abstract: An electromagnetic clutch is disposed between a drive source and a driven device for connecting and disconnecting the drive source to and from the driven device, respectively. The electromagnetic clutch includes a body rotatable by the rotative power from the drive source and an armature faced to, but normally spaced from the rotatable body. An exciting solenoid when energized moves the armature into an engaging position where the armature is attracted and urges against an end face of the rotatable body. A bearing is disposed between a fixed member of the driven device and the inner peripheral surface of the rotatable body for rotatably supporting the rotatable body on the fixed member. A cylindrical cover member is fixedly mounted, independently of the bearing, on a portion of the inner peripheral surface of the rotatable body between an axial end face thereof and the bearing.Type: GrantFiled: May 20, 1982Date of Patent: May 22, 1984Assignee: Nippondenso Co., Ltd.Inventors: Reijiro Okano, Kiyoshi Usami

Patent number: 4432446Abstract: An electromagnetic coupling apparatus for interrupting power transmission is disclosed in which a terminal of a magnet coil for attracting an armature to a rotary body is connected with an electrical terminal of an electric connector directly outside of a fixing member without using a lead wire or the like therebetween. A stopper is secured in direct contact or with a small gap to a recess formed at part of the fixing member, thus preventing the rotation of the yoke including the magnet coil.Type: GrantFiled: May 26, 1981Date of Patent: February 21, 1984Assignee: Nippondenso Co., Ltd.Inventors: Reijiro Okano, Kiyoshi Usami
