Title: Steam turbine by-pass device
Inventor: HASEGAWA HIROYUKI
IPC: F01K9/04
Filed: 1988-03-23
Abstract: PURPOSE:To prevent water hammer in a condenser by providing each detection means for the enthalpy and the flow rate of steam in a high-pressure steam by-pass pipe, a computation means for the enthalpy after the mixture of cooling fluid, and a control means for a cooling fluid quantity. CONSTITUTION:The energy of by-pass steam is obtained from the enthalpy and the flow rate of steam in a high-pressure steam by-pass pipe 70, which have been obtained from each signal detected by a pressure transmitter PX1, a temperature transmitter TX1, and a valve opening transmitter VX1. The energy of cooling fluid is obtained from TX2, TX2, VX2 in the same way, and the energy of the fluid is obtained after these energies are mixed together. Then the energy of the fluid after the mixture is compared with a known energy acceptable by a condenser 40, so that the excessive and the insufficient valve opening of a cooling fluid quantity control valve 84 is obtained by computation. And whether the temperature of the fluid after the mixture is accepted by the condenser 40 or not is judged, so that the valve opening of the control valve 84 is controlled in advance. This way results in the cancellation of delay in detecting the temperature and the pressure of the device concerned, so that water hammer and the like can be prevented.

Patent JP-2000265429-A (JP)
Title: Fence
Inventor: ZENIN HIDEO
IPC: E04H17/16
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a fence for stably radiating the light and excellent in visibility by forming a light emitting part by arranging a self-light emitting element in an upper part of columns erected at proper intervals on the ground surface. SOLUTION: A column cap 1 is fitted to and installed on the upper end of a column 7. A light emitting part 5 installed in this column cap 1 radiates the light from the upper end of the column 7 to improve visibility of a fence. When a solar battery is used as a power source, generated electric power is stored in a storage part, and a self-light emitting element emits the light by supplying the electric power stored in this storage part to the self-light emitting element of the light emitting part. Thus, the fence can be installed in a power source nonexistent place, and since the self-light emitting element semipermanently emits the light in the night, installation is facilitated, and the fence can be stably used over a long period. When the self-light emitting element of the light emitting part 5 arranged in an upper part of the column 7 is made to flashily emit the light at an interval of 2 to 5 times/sec, visibility is enhanced, and the self-light emitting element can be used for many hours by saving electric power.

IPC: H01J37/22
Filed: 1978-06-06
Abstract: PURPOSE: To simplify the focusing of the center part of a photographing field by allowing the center of the photographing field to agree invariably with the center of a small fluorescent plate even if tilting.  
     CONSTITUTION: Rotary disc 23 is rotated to turn gear 21 via crown gear 22 in the direction of arrow F, so that arms 14a and 14b will rotate around axes 15a and 15b by pin 24a in the same direction. In this case, since stopper 26a and lever 25 gear with the rotation of gear 21, large gear 17 will not rotate. Therefore, since gear 19 rotates gearing with fixed gear 19 at the same time as gears 19 and 18 rotate in the same direction, gear 18 rotates in the direction of arrow G, so that small fluorescent plate 11 will tilt as shown by one-dot chain line (b). Here, when axial centers  of rotary axis 12a and support axis 15a, and an intersection point with light axis Z  on the surface of small fluorescent plate 10 are denoted by D and E, and C, equalizing distance DE to distance DC positions the center at point C' on light axis Z  even if small fluorescent plate 10. Consequently, the focusing of an electron-beam  image can be attained by using loupe 27.

Title: Vertical magnetic recording and reproducing device
Inventor: WATABE HIROYUKI
IPC: G11B5/17
Filed: 1984-04-06
Abstract: PURPOSE:To make recording and reproducing operations at high frequency bands under a condition where no bad influences, such as waveform distorsion, etc., occur, by closing the circuit of a non-used winding out of plural windings woud around the auxiliary or main magnetic pole of a magnetic head with a prescribed resistance value. CONSTITUTION:At the time of recording mode, a luminance signal Y and chrominance signal C inputted in terminals 11 and 13 are converted into a rectangular wave of a prescribd level at a limiter 16 after passing through a mixer 15 and the rectangular wave becomes a record signal having a fixed electric current through a recording amplifier 17 and constant-current circuit 18. The signal is supplied to the winding of an auxiliary magnetic pole 20 and vertically and magnetically recorded on a tape by means of a main magnetic pole 21 facing the auxiliary magnetic pole 20. At the time of reproducing mode, signals reproduced from a tape become luminance signals Yand chrominance signals C through an amplifier 24 and demultiplexer 25. The luminance signals Y and chrominance signals C become reproduced video signals when mixed at a mixer 31 after they are FM-demodulated at FM demodulators 27 and 29 and the reproduced video signals are sent out from an output terminal 32. By closing the circuit of a non-used winding 40 or 50, interference between plural windings wound around one magnetic pole 20 is eliminated and, threfore, recording and reproducing at high frequency bands can be performed without having any peculiar impedance and phase characteristic.

Title: Method for adjusting access of communication system
Inventor: MEEDEI EMU NASEI
IPC: H04L12/28
Filed: 1990-03-20
Abstract: PURPOSE: To eliminate unfairness between stations by making each station maintain an access request queue representing temporary mutual relation and giving every station a different delay for an access request to be inputted to the access request queue. CONSTITUTION: When a detecting means 49 detects that an external request count is 0 on a bus B, a local request being on standby in a buffer 51 is gated by a gate 53. At the same time, a value which is just sent and inserted into an FIFO request queue 41 through a line 55 is marked as a local request. Each work station is provided with a delay element 71 in addition to the FIFO request queue 41. The delay is so selected that the propagation time of a slot from an access point 67 to an entry 69 of a bus A becomes equal among all the stations of the system. Consequently, each station is given an equal chance.
