Title: Method and device for grounding detection
Inventor: YASUKAWA SABURO
IPC: H02H7/26
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To obtain a high precision ground detection device which is not influenced by tap change of a PC earth system. SOLUTION: Ground detection sensors 3 are provided at a plurality of positions of a distribution system 2 which has a main transformer 1 whose neutral is earthed with a Pedersen Coil(PC) 4 with taps 4a. Zero phase voltages V0 and zero phase currents I0 which are detected by the respective sensors 3 are received by ground detection circuits 102 to detect the ground and judge the direction. If the polarity of V0-I0 phase difference (for instance 90±) with V0 as a reference is (+), it is judged that the ground point is on the terminal side and, if the polarity is (-), it is judged that the ground point is on the power supply (transformer) side. A frequency with the phase difference is evaluated is not lower than a system resonance frequency determined from a reactor L and a ground capacitance C.  For instance, the frequency is within a frequency region which is not lower than a maximum system resonance frequency when L of the PC 4 is minimum.

Title: Information communication system
Inventor: MIYAMOTO KOUICHI
IPC: H04L69/40
Filed: 1981-12-07
Abstract: PURPOSE:To execute an efficient countermeasure at a transmitting source when a transmission destination is impossible for reception in a facsimile communication network, by recording transmitted information at the transmitting source. CONSTITUTION:A terminal device 1 when receiving a command sent from a terminal device 1' as an answer to a transmission notice decodes the contents of a command stored in a buffer to decide on whether the device 1' is possible of reception or not. When possible, information at an input part is transmitted to the device 1' through a modulating circuit. The device 1' starts a printer on receiving the information to perform recording operation based upon the received information. On the other hand, when a control part decides that the device 1' is not ready, a switch is changed over to input information from a line 8 and the information at the input part is sent to and recorded on the printer.

IPC: C21D1/00
Filed: 1987-08-07
Abstract: PURPOSE:To carry out cooling causing no coloring at the surface of a metal and requiring merely low cost of equipment, by bringing a coolant in which alcohol and surface active agent are used in combination with water into contact with a metallic material. CONSTITUTION:A coolant is prepared by incorporating, by weight, 1-<10% of alcohol and 0.1-10% of surface active agent into water. This coolant is brought into contact with a metallic material to cool the metallic material. It is preferable that a reducing gas is also brought into contact with the metallic material in the course of the above procedure. Aliphatic alcohol, etc., such as ethanol and hexanol, are used as alcohol, and, as surface active agent, a nonionic, cationic, or amphoteric surface active agent is used. By this method, bright cooling is enabled and this material becomes capable of meeting the recent demand for the elimination or simplification of equipment for removing coloring at the surface of a metallic strip.

Title: Sublimable thermal transfer image receiving sheet
Inventor: NOGAWA CHIHARU
IPC: B41M5/382
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent an inadvertent cutting-out of an image receiving sheet in the case of the sheet is folded and to maintain suitable image receiving performance by penetrating broken line-like perforated lines through the sheet in which an image receiving layer is arranged on a surface of a sheet-like support, and dividing the sheet into a plurality along the perforated lines. SOLUTION: Broken line-like perforated lines penetrating from a front surface to a rear surface of the sublimable thermal transfer image receiving sheet are formed on the sheet, and the sheet is divided into a plurality along the perforated lines. In this case, the perforated lines are set, for example, in a zigzag state, or formed in broken line-like or solid line-like state without zigzag state. That is, the perforated lines are formed suitably in combination by the broken line and the solid line of the zigzag state and the broken line and the solid line without zigzag state. Thus, if the sheet is folded due to a certain reason, the sheet is effectively prevented from being inadvertently cut out, and the sheet is simply cut out when required. Accordingly, image receiving performance of the sheet can be maintained suitably.

IPC: B29C45/17
Filed: 1986-08-26
Abstract: PURPOSE:To make it possible to easily scrape off and discharge heat resisting engineering plastic and to easily change over resin to general-purpose engineering plastic or general-purpose resin by a method wherein the changeover of resin is done by once changing over to low viscosity resin, the range of molding temperature of which overlaps with that of the previous resin and which contains filler such as glass fibers or the like. CONSTITUTION:After the finish of molding, the resin in a hopper 6 is discharged from a discharge hole 6a. Next, a mixture of high fluidity grade resin and glass fibers (displacement resin) is employed as low viscosity resin containing filler such as glass fibers or the like and charged in a temporary displacement resin storage device 11. Next, the action time for resin changeover, the rotational frequency of a screw, the back pressure of the screw, the temperature of a heating cylinder during the resin changing-over action and the molding temperature of a general-purpose resin, which is the aimed-at resin of the resin changeover, are set through the operating panel 20 of a controlling device 10. After that, general-purpose resin is charged in the hopper 6 and the resin changing-over action is started by the switch of the operating panel 20. Next, when the temperature of the heating cylinder 1 reaches the set temperature, a resin feeding device 13 feeds the replacement resin through a resin drop hole 14 into the interior 1a of the heating cylinder 1. At the same time, the rotation and injection of the screw 2 are repeated by the command of a screw action controlling CPU 23, resulting in easily chaning-over resin to the replacement resin.

Inventor: KASHIWA SHIRO
IPC: F25B1/00
Filed: 1994-07-18
Abstract: PURPOSE:To shorten a time until a refrigerant system is stabilized and improve a reliability in operation of a compressor. CONSTITUTION:When a heating operation is carried out, each of condensing temperature Tc, evaporating temperature Te and refrigerant discharging pipe temperature To is detected by each of temperature sensors 11, 10 and 13, respectively. Then, a target discharging pipe temperature Tm is calculated to perform a discharging pipe temperature control. Concurrently, a sub-cool control target value SET.SC is calculated in reference to a difference between a target discharging pipe temperature Tm and a refrigerant discharging pipe temperature To in a discharging pipe temperature control with a second degree of opening control means 22b. The sub-cool control target value SET.SC is varied in response to an amount of circulation of refrigerant (for example, an operating frequency of a compressor 1) and concurrently a correction is performed with a variation in the refrigerant discharging pipe temperature To. Then, a degree of opening of an electrical expansion valve 4 is carried out in order to cause it to approach against the calculated sub-cool control target value SET.SC (a sub-cool control). With such an arrangement it is possible to shorten time in which a relative humidifying operation is carried out.
