Title: Method and device for controlling accelerator
Inventor: NAKAYAMA HISAHIDE
IPC: H05H13/04
Filed: 1990-04-16
Abstract: PURPOSE:To facilitate control of putting a lump of charged particles of a front stage ring upon a rear stage ring by making the frequency of a front stage high-frequency accelerating device identical to the frequency of a rear stage high-frequency accelerating device, and determining the emitting timing from the front stage ring and the incident timing to the rear stage ring from the phase difference between the two frequencies and implementation of conveyance delay on the beam transport path. CONSTITUTION:The frequency of a high-frequency accelerating device 20 of a front stage ring 2 is made identical to the frequency of a high-frequency accelerating device 21 of a rear stage ring 3, and the emitting timing of a lump of charged particles from the front stage ring 2 is determined according to the phase difference between the two frequencies. A delay from this emitting timing is made in the amount corresponding to the charged particle conveying time of a transport path 25, and thereby the incident timing to the rear stage ring 3 is determined. Even in case the acceleration frequency is changed for altering the acceleration, therefore, lump of charged particles conveyed from the front stage ring 2 can be put easily on a bucket of the rear stage ring 3.

Title: Non-contact rotor and signal transmission method, means and device for the rotor
Inventor: SHIGETOMI TAKASHI
IPC: G06F15/76
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To effectively arrange many lines on the same plane and to improve the packing density at a low cost by transmitting plural signals accordant with the number of electromagnetic connections via these connections which are secured between a balanced microstrip line of a rotor and a fixed balanced microstrip line. SOLUTION: Every phase shifter 301 adjusts the electrical length of every balanced microstrip line 300. The lines 300 are bonded on or embedded into a dielectric substrate 302. Then every shifter 301 is inserted between the lines 300 and adjusts the phase to change the apparent electrical length of the lines 300 and to shift the dead points of the lines 300. Thus, the communication is attained with desired signal frequency. In other words, an antenna line consists of the balanced microstrip lines 300 to reduce the leakage of bidirectional electromagnetic fields. As a result, many lines can be formed on the same plane in comparison with a case where a single microstrip line is used.

Title: Manufacture of semiconductor device
Inventor: TOYODA ARATA
IPC: H01L21/322
Filed: 1989-04-17
Abstract: PURPOSE:To put only substrates, predictors of which are kept within a standard, into the next process by measuring the recombination time of the minority carriers of a thermally treated semiconductor substrate and predicting the quantity of oxygen deposited after the completion of all processes midway of a manufacturing process. CONSTITUTION:When the recombination time tau of the minority carriers of each silicon substrate after the completion of a field oxide-film forming process is measured through an optical attenuation method and compared with the quantity of oxygen deposited (the difference of the interstitial oxygen concentration of the silicon substrates before charging to the manufacturing process of a semiconductor device and after the perfection of all processes) measured after the completion of all processes of the manufacture of a MOS type IC, both the recombination time and the quantity of oxygen deposited display extremely excellent correlation. Consequently, when tau after the field oxide-film forming process in which the reduction of tau is brought to a sufficiently stable state is inspected, the quantity of oxygen deposited of the substrate after the completion of all processes can be predicted midway of the processes. Accordingly, only the substrates, the predictors of the quantities of oxygen deposited of which after the completion of all processes are kept within a standard, can be put into subsequent processes.

Abstract: PROBLEM TO BE SOLVED: To provide a leakage detection method which can perform the detection of the leakage of a hot water supply system simply and besides accurately without needing tools or hands, and its hot water supply system. SOLUTION: A heat source 1 is connected to a hot water heater 30 by a supply pipe 23 and a return pipe 24, and it is connected to a bathtub 20 through a supply reheating pipe 21 and a return reheating pipe 22.

Furthermore, the controller 11 closes the hot water pouring valve 9 when the hydraulic pressure (pressure) gets over a specified value, and monitors the subsequent pressure of a water level sensor 10. Then, in case that the pressure detected with the water level sensor 10 falls down by a specified value or over within a specified time, the controller 11 judges that leakage is occurring in the circulation path for reheating.  Therefore, the detection of the leakage of the hot water supply system can be performed simply and with accuracy without needing tools or hands.

IPC: F15B11/08
Filed: 1994-05-12
Abstract: PURPOSE:To prevent the generation of shock, and thereafter to make the ordinary switching operation possible without adding the restriction by gradually operating the changeover of a switching valve at the time of starting, namely, the movement of an actuator at the time of starting. CONSTITUTION:When an operating valve 5 is operated to the wind-down side, the secondary pressure of a wind-down side pressure reducing valve 5b is supplied as the pilot pressure to a wind-down side pilot chamber 3b of a control valve 3 through a first position A of a changeover control valve 9 and a first pilot passage 11. The control valve 3 is thereby removed to the wind-down side so as to start the discharge of the oil. At this stage, since the oil of a secondary oil passage 7 is throttled by a throttle valve 10 and since the oil discharged from the first pilot passage 11 is divided to a pilot chamber 9a of the changeover switching valve 9, flow quantity of the oil to be supplied to the pilot chamber 3b of the control valve 3 is a little, and the spool of the control valve 3 is gradually moved. Consequently, since a winch motor l starts to gradually move in the wind-down direction, the generation of shock is eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide an energy feeding system to a variable load which can follow the variation of the load. SOLUTION: In a normal condition, an even energy is fed to a variable load 4 from an energy source 1 such as a fuel cell. When the energy necessary to the variable load 4 is smaller than that in the normal condition, an excessive energy is absorbed and stored to an absorption-storing-feeding means 5.

That is, the variation part of the load which cannot be followed by the energy source 1 is covered by the energy stored in the absorption-storing-feeding means 5. By such an energy regulation, the energy utilizing efficiency of all the system is improved.
