Patent number: 9931718Abstract: A pair of upper and lower pressure rollers 3, 4 is disposed so that their axes 15, 16 are tilted in a horizontal plane in respective directions opposite to each other with respect to a straight line perpendicular to a welding line of a joint portion J. The pressure rollers 3, 4 are positively driven by corresponding electric motors 63, 64 to thereby roll the joint portion. Thus, steps defined at the joint portion can be smoothed and a step gradient can be reduced to ensure a high degree of joint strength. Thus, it is possible to prevent a step portion from being interfolded into the base material of the meal plates 5, 6.Type: GrantFiled: July 11, 2008Date of Patent: April 3, 2018Assignee: PRIMETALS TECHNOLOGIES JAPAN, LTD.Inventors: Shinichi Kaga, Noriaki Tominaga, Takehiko Saito, Mitsuru Onose, Yasutsugu Yoshimura, Hirotoshi Tagata, Yujiro Watanabe, Satoru Zenitani, Ikuo Wakamoto

Patent number: 8474280Abstract: A deviation calculating unit 42 calculates a deviation between an internal temperature detected by a temperature sensor 35 and a target temperature provided from a target temperature setting unit 41 for each predetermined time period. The deviation is integrated by a deviation integrating unit 46. When the integrated value exceeds a predetermined reference value, a rotational speed of an inverter motor that drives a compressor is increased. Therefore, for example, even if an internal temperature temporarily rises because a door is opened temporarily and outside air flows into a storage compartment, because there is no sudden change in the integrated value of the temperature deviation and the rotational speed of the compressor does not react in an oversensitive manner and rapidly increase. Consequently the control is stable. Thus, an unnecessarily oversensitive response to a sudden change in an internal temperature can be prevented, enabling operation at a higher efficiency.Type: GrantFiled: February 26, 2007Date of Patent: July 2, 2013Assignee: Hoshizaki Denki Kabushiki KaishiInventors: Naoshi Kondou, Akihiko Hirano, Shinichi Kaga, Masahide Yatori, Hideyuki Tashiro

Patent number: 8365543Abstract: A liquid refrigerant from a compressor and a condenser is alternately supplied to a cooling device for the freezing room 27F and an evaporator for refrigeration room through a three-way valve, so as to conduct the cooling of a freezing room and a refrigeration room. When the thermal load condition of a refrigerating cycle is light, the three-way valve switches to the “F side opened-state” after the compressor is stopped, and thereby conducting pressure balancing, without the liquid refrigerant flowing into the evaporator for refrigeration room. A cooling storage, wherein from one compressor a refrigerant is selectively supplied to multiple evaporators, is constituted so as to prevent one evaporator side from becoming a supercooled state, and furthermore, quickly conduct pressure balancing after stop of the compressor.Type: GrantFiled: March 12, 2007Date of Patent: February 5, 2013Assignee: Hoshizaki Denki Kabushiki KaishaInventors: Naoshi Kondou, Akihiko Hirano, Masahide Yatori, Shinichi Kaga, Hideyuki Tashiro

Patent number: 8209991Abstract: The liquid refrigerant from the compressor 20 and the condenser 21 is alternately supplied to the cooling device for the freezing room 27F and the evaporator for the refrigeration room 27R through the three-way valve 24, so that the freezing room and the refrigeration room are alternately cooled. Here, the ratio of the refrigerant supply time to each evaporator is controlled based not on a deviation between a target temperature set for each storage room and an actual storage room temperature measured in each storage room, but on an integrated value obtained by integrating the difference of these deviations. In a cooling storage, in which from one compressor a refrigerant is selectively supplied to multiple evaporators respectively disposed in multiple storage rooms of varied thermal loads, a one-storage room cooling mode is prevented from being unnecessarily switched to a alternate cooling mode.Type: GrantFiled: March 13, 2007Date of Patent: July 3, 2012Assignee: Hoshizaki Denki Kabushiki KaishaInventors: Naoshi Kondou, Akihiko Hirano, Masahide Yatori, Shinichi Kaga, Hideyuki Tashiro

Patent number: 7975497Abstract: In a refrigeration unit including a variable performance compressor driven by an inverter motor, a sensor is configured to detect a physical amount corresponding to a refrigerant pressure on the high-pressure side of a refrigerant circuit. A measured value of the physical amount is compared with a first reference value corresponding to a first predetermined pressure of the refrigerant and a second reference value corresponding to a second predetermined pressure lower than the first predetermined pressure. A protective operation can start if the comparison result indicates that an actual refrigerant pressure is higher than the first predetermined pressure. The performance of the compressor can be gradually lowered if the comparison result indicates that an actual refrigerant pressure is between the first predetermined pressure and the second predetermined pressure.Type: GrantFiled: June 27, 2007Date of Patent: July 12, 2011Assignee: Hoshizaki Denki Kabushiki KaishaInventors: Shinichi Kaga, Akihiko Hirano, Takeshi Ueda
