Title: Production of tert-butyl alcohol
Inventor: KURAGANO MORIMASA
IPC: B01J31/00
Filed: 1984-05-02
Abstract: PURPOSE:To obtain advantageously the titled compound in reacting isobutylene with water in the presence of a cation exchange resin in many stages, by increasing the 4C concentration to be fed to the second reaction zone to a value higher than that in the first reaction zone with a distillation zone provided between the first and the second reaction zones. CONSTITUTION:Isobutylene or a hydrocarbon containing the isobutylene is reacted with water in the presence of a cation exchange resin in many stages to produce the titled compound [tert-butyl alcohol (TBA)]. In the process, a reaction mixture 3 obtained from the first reaction zone (A) is separated into the unreacted raw material 9 and an aqueous solution 4 of the TBA in a distillation zone (B) to feed the former 9 to the second reaction zone (B), and part 6 of the latter 4 is fed to the first reaction zone (A) and/or the second reaction zone (B). In this step, the composition is decided to give a uniform phase of the TBA-water- 4C hydrocarbon mixture near the raw material feed inlet in both reaction zones (A) and (B). The 4C concentration in the above-mentioned mixture to be fed to the second reaction zone (B) is higher than the concentration of the mixture to be fed to the first reaction zone (A) to advance smoothly the reaction and afford the aimed compound in high selectivity and yield.

Title: Semiconductor nonvolatile memory device
Inventor: HAGIWARA TAKAAKI
IPC: G11C17/00
Filed: 1986-04-18
Abstract: PURPOSE:To obtain a metal nitride oxide semiconductor (MNOS) type memory element having a high working speed and a high density of integration by a method wherein a memory matrix is formed by assembling the MNOS element formed with a polycrystalline silicon gate and a switching MOS transistor. CONSTITUTION:A transistor on the left side is an MNOS element and a MOS transistor on the right side is a switching transistor. These transistors are consti tuted by forming an Si3N4 film 15, a very thin SiO2 film 17, and a gate insulat ing film 20 on a p(n) type Si substrate 11. Also, each of gate electrodes 18 and 19 consists of polycrystalline silicon. Consequently, as the word wire of the memory matrix is turned to polycrystalline silicon, an Al wiring can be used for a data wire, and also as there is switching transistor, it is unnecessary to form the MNOS element into an offset structure. Moreover, the area of a memory cell can be made small, signal lag time is made short, and a high speed operation can be achieved.

Title: Power generation system burning on fowl droppings
Inventor: MORISANE KIYOSHI
IPC: H02N11/00
Filed: 1988-04-08
Abstract: PURPOSE:To make the most of combustion energy of fowl droppings effectively, by dehydrating and drying raw fowl droppings and by burning them up as fuel in a combustion furnace. CONSTITUTION:A generation system temporarily stores raw fowl droppings in a storage tank 1 and supplies them to a hydroextractor 2 to dehydrate not more than 70% of water. The dehydrated water is put to a sewage disposal 5 and drained off. Then the dehydrated fowl droppings are supplied to a dryer 6, forced to dry in not more than 25% of water and taken out from the end of a kiln. The effluent gas is then exhausted outside through a dust collector 8 and a fan 9. The dried fowl droppings are then supplied to a combustion furnace 10 and burnt up as fuel. 40%-70% of the burnt gas is fed back to the abovementioned dryer 6 and the remaining burnt gas is supplied to a boiler 14 of the next process to make it a heat source. Thus the high-pressure gas is obtained, which rotates a steam turbine 16 through a steam separator 15 and generates the power with a generator 17.

Title: Spark plug structure for petroleum combustion device
Inventor: KATSUMATA KOJI
IPC: F23Q3/00
Filed: 1994-03-31
Abstract: PURPOSE:To enable a stable electrical discharging and ignition to be carried out even if a wick having a superior electrical conductivity or a wick stained with tar is used. CONSTITUTION:An electrical discharging electrode 3 is arranged in opposition to a side surface of a wick 2 installed at a clearance of a wick storing cylinder 1. An opposing electrode 4 is oppositely arranged upwardly against the electrical discharging electrode 3 and then an insulating member 5 is arranged between the side surface of the wick 2 and the electrical discharging electrode 3. Due to this fact, even if the wick 2 is stained with tar or made of raw material having a superior electrical conductivity, the insulating member 5 prevents an electrical discharging from being applied to the wick 2 having a superior electrical conductivity, resulting in that an electrical discharging is performed between the electrical discharging electrode 3 and the opposing electrode 4, a positive ignition can be attained.

Title: Image display device
Inventor: KAWAKAMI KATSUYUKI
IPC: H01J29/88
Filed: 1994-04-26
Abstract: PURPOSE:To reduce an electric field radiated from the front face of the image display device. CONSTITUTION:In order to cancel an electric field 60 to be radiated from the front face of a cathode-ray tube(CRT) 1, an output voltage 12 converting the waveform of a pulse voltage 8, which polarity is reverse to that of a pulse voltage 7 in a horizontal cycle to be provided from a terminal T3 of an induction coil fitted to a flyback transformer inside a high voltage deflecting circuit through a differentiation circuit 11 is impressed to an electrode 4 fitted to a radiation-proof band 5 of the CRT 1. Since this electric field waveform 60 and an electric field waveform 15 generated from the radiation-proof band 5 are canceled each other by impressing the waveform converted voltage 12 according to this method, the electric field 60 radiated from the CRT 1 is effectively reduced. Thus, the electric field radiation from the CRT can be effectively reduced by impressing the voltage of the reverse polarity to the cancel electrode for the electric field radiated from the front face of the CRT.

Title: Communication controller
Inventor: SHIOMI TOMONORI
IPC: H04L12/40
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain a communication controller that realizes two-way communication which does not give disturbances on a transmission signal of other communication controllers or a transmission signal of other system or not receiving disturbance, even if the gain of a 1st transmission line fluctuates. SOLUTION: When communication is stated from a slave station 2 to a master station 1, the slave station 2 sets a signal transmission level based on information of a transmission level of preceding communication stored in a transmission level memory 22 and then sets a signal transmission level, based on the information of a transmission level notified from the master station 1 for succeeding communication. Thus, even if the gain of an incoming transmission line 4 fluctuates, the signal transmission level of the slave station 2 is corrected to a proper value for each communication.

Title: Method and device for increasing wall thickness of thin-walled cylindrical body
Inventor: TANAKA HARUMA
IPC: B21D19/16
Filed: 1983-05-23
Abstract: PURPOSE:To increase the wall thickness of a thin-walled cylindrical body to about twice the thickness of a blank plate with one stage by relieving the bulging when said body is axially compressed while pressing the same with a segmental die thereby increasing the thickness. CONSTITUTION:The operator lifts an upper die 23 together with an attaching body 29, inserts a thin-walled cylindrical body 11 to a male die 21, and descends the die 23 to engage the top end of the body 11 with a step 25. A segmental die 27 is inward pressed toward the radial direction by the force generated when both upper and lower dies 23, 24 approach each other. When the die 23 moves further downward, the body 11 is forced to contract axially and the dies 27 are forced to expand but the force set by a die cushion via a cushion pin 28 is acted toward the central part and therefore the bulging is suppressed. When the die 23 descends further, the die 24 is pressed by the slope 26 of the die 27 and is descended. The die 27 escapes to the outside while maintaining the specified pressure. The thickness of the cylindrical body is successively increased in the part made after said die escapes.
