IPC: C10B21/00
Filed: 1981-07-29
Abstract: PURPOSE:To suppress the heat dissipation from the combustion chamber of a coke oven through the opening of the outer surface of the chamber and through the openable lid of the chamber, by inserting a refractory insertion having a  temperature measuring hole detachably into a through-hole extending through  the inner and the outer surfaces of the upper wall of the combustion chamber. CONSTITUTION:A refractory insertion 10 having a temperature measuring hole 10a is inserted detachably into the through-hole extending through the inner and the outer surfaces of the upper wall of the combustion chamber (hereinafter called as flue) 12 of a coke oven. During the normal operation of the coke oven, the refractory insertion 10 is inserted into the flue cylinder 2a to minimize the radiant heat radiated from the inner wall of the flue to the lower face of the flue lid 3, thereby suppressing the heat dissipation from the flue lid 3. In the case of measuring the temperature of the bottom of the flue 1 by opening the flue lid 3, the measurement can be carried out acdurately, the heat dissipation through the top opening of the flue cylinder 2a during the measurement can be remarkably suppressed, and the temperature measurement operation can be performed safely and easily.

Title: Start-stop method of multistage reversible pump-turbine
Inventor: OKADA MASAYASU
IPC: F04B15/04
Filed: 1979-09-19
Abstract: PURPOSE: To provide a smooth start or stop, by depressing water level at the time of clearing primary critical speed for reducing the hydraulic exciting force.  
     CONSTITUTION: As revolution draws near that of a primary critical speed, an air valve 17 is opened and water level around a runner 3 is lowered. As a result, the runner 3 idles. When the revolution is sufficiently reduced after clearing the primary critical speed with idling, an exhaust valve 19 is opened to exhaust air, the runner 3 is refilled with water, the hydraulic exciting force is reduced, and the multistage reversible pump-turbine which continues to be reduced in speed also after the water- refilling stage comes to a standstill. Thus this system can provide smooth start and stop of the pump-turbine.

Title: Image pickup element vibrating device
Inventor: HATACHI SHINJI
IPC: G03B13/32
Filed: 1986-05-23
Abstract: PURPOSE:To facilitate lens assembling and to reduce its cast by adopting the constitution in which a drive circuit board is arranged in parallel with the optical axis of an image pickup lens. CONSTITUTION:The drive circuit board 5 is arranged in parallel with the optical axis 3 of an image pickup lens 1a.

Title: Navigation system
Inventor: KAKIUCHI KUNIO
IPC: G01C21/34
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To obtain a navigation system by which the time required for a vehicle can be shortened, by a method wherein a bypass route which is not through a grade crossing is searched again when it is judged that the vehicle passing through the grade crossing in the closed time zone of the crossing. SOLUTION: In an operating-information acquisition part 11, operating information on a train is acquired from an operating control center or the like. The operating information refers to information which is used to compute a timing at which a grade crossing is closed such as the type, the position, the speed or the like of every train. When the train cannot be operated normally due to a disaster or the like so as to repeat a stop or the like, it is judged whether the grade crossing is closed for many hours, whether the train reaches a part just before the grade crossing or whether emergency information is issued. A timing at which the closing time and opening time of the grade crossing are computed is delayed in a range in which a vehicle can pass. Then, the closing time and the opening time of the grade crossing are computed.  When the computed time is for the present operating state of the train, taking into consideration a change after that, the transmission of information is awaited until the vehicle reaches the by-pass possible point (a turning point). A computing operation is repeated always on the basis of latest operating information, and the reliability of a navigation system is enhanced.

Title: Low-pressure rare gas discharge lamp device
Inventor: ADACHI HIROMI
IPC: G03B27/54
Filed: 1991-05-24
Abstract: PURPOSE:To achieve uniform, and high brightness in a simple and, low-cost structure by rectifying high frequency created by an inverter in full waves to apply it to a discharge lamp. CONSTITUTION:A high frequency AC inverter 15 is connected to leads for the cathode 10 and the anode 11 of a hot cathode low-pressure rare gas discharge lamp 12 via a diode bridge circuit 14 to form a lighting circuit 16. The high frequency AC output of the inverter 15 is rectified in full waves by the diode bridge circuit 14 and applied to the discharge lamp 12. At this time, because DC voltage is applied, movement streaks flow in a longitudinal direciton at a high speed without resting and still, because a pulsating current flows, lamp voltage and starting voltage are valued nearly to AC ones. It is thus possible to achieve uniform, and high brightness with the inverter and the diode bridge circuit in a simple, and low-cost structure.

Title: Noise blanker
Inventor: NISHI YUUJI
IPC: H04B1/10
Filed: 1981-07-31
Abstract: PURPOSE:To form a noise blanker with only a noise induction line and a switch circuit, by providing a noise induction line which receives the electromagnetic connection or electrostatic connection at an end to a noise generating source. CONSTITUTION:Both a mixer MIX and a filter BPF are a part of the main route of a radio receiver, respectively. A noise blanker NB consists of a noise induction line NIL and a switch SW. An end of the line NIL is extended to the position near a noise generating source NS so that the noise N can be picked up directly with the electromagnetic induction or electrostatic induction. The line NIL is independent from an antenna and extended to the position near the source NS through the inside of a car in the case of a car. For instance, the spark discharge caused by an ignition plug is induced electrostatically to the line NIL to turn off the switch SW. Thus the output of the MIX is not transmitted to and after the filter BPF.

Abstract: PURPOSE: To reduce NO x  density in exhaust gas discharged from sintering furnaces by forming a reduction layer in sintering beds by reducing blast volume and recycling exhaust gases, produced at the firing zone and cooling zone of furnace where no reduction layer os formed, into the fire layer including the reduction layer.  
     CONSTITUTION: Air mixed with recycled gas at mixer 18 is sent to wind box 8, and a required amount of the air is delivered through feed material bed F and a reduction layer is formed. Exhaust gases discharged from firing zone A and cooling zone B are gathered by sucking through suction pipes 7 and 4, and then the gases are sent to mixer 18. Exhaust gases produced at the middle zone of furnace are discharged through outlet of flue 21. By this procedure, exhaust gases discharged from the middle zone of furnace are remarkably reduced in NO x  density.
