Title: Thermal head
Inventor: KATO YOSHIMASA
IPC: B41J2/335
Filed: 1988-02-10
Abstract: PURPOSE:To achieve prevention of a printing concentration characteristic from deterioration caused by a gather of paper refuse, and damage and wear of a protective film by smoothly feeding thermosensible paper in printing and recording, by a method wherein an end surface in contact with a heating resistant band part of a conductive layer is formed in a tapered state to have a smooth surface. CONSTITUTION:For instance, a TaSiO resistor layer 2 of 0.1mum and an Al conductor layer of 1mum are formed by coating on a surface of a ceramic substrate 5 to which a heat accumulating layer 4 is attached, and then, they are successively processed by chemical etching so as to become a pattern corresponding to a heating resistant band part 6. Then, positive type photoresist is used as an etching mask. An etchant where a mixed solution of 5:3:1:1 in phosphoric acid, acetic acid, nitric acid, and water is mixed with 1% NH4F is heated at 45 deg.C and aluminum is etched. By mixing of above-mentioned NH4F, a penetration speed to an adhesive surface between the resist and Al of the etchant can be adjusted, a taper angle alpha of conductive tapered parts 7a and 7b can be controlled, and said angle alpha is preferably 20-40 degrees. Then, when a protective film 3 is formed by using Si3N4 of 5mm, since the heating resistor part is smoothly formed, pulse life can be prolonged.

Title: Magnetic field induction generator-motor
Inventor: KUWANO MITSUO
IPC: H02J7/00
Filed: 1998-01-04
Abstract: PROBLEM TO BE SOLVED: To prevent the speed of the magnetic fields of a field system and the speed of the rotating magnetic field of an armature from being saturated to a certain degree so that electricity is continued to be generated by means of a generator and a generator-motor, by joining a SI thyristor with the switching circuit gate of the generator. SOLUTION: In a power generating apparatus, a SI thyristor is connected with the switching circuit of a generator 8. As the result of the SI thyristor being installed in the switching circuit, switching from off state to on state is performed in one millionth second. Therefore, amplifying effect can be obtained thanks to an avalanche amplifying phenomenon caused by collision of electrons accelerated at reverse voltage with the electrons of semiconductor. Further, since the SI thyristor switches from off state to on state in one millionth second, the speed of the magnetic fields of a field system 1 and the speed of the rotating magnetic fields of an armature 4 is not saturated to a certain degree, and the generator 8 keeps on sensing any change in magnetic fields and further rotating.

IPC: G21C7/10
Filed: 1990-02-09
Abstract: PURPOSE:To entend the life of a control rod and to reduce the length thereof by providing a hole wherein a plug supporting a B4C pellet on the upper surface thereof and permitting liquid metal and He gas to pass is sealed to a lower end plug by solder to the end part on the side of the lower end plug of a cladding tube. CONSTITUTION:A B4C pellet 1 is arranged to the plug 10 provided in a cladding tube 2 hermetically sealed by plugs 3, 4 to be almost held to a vacuum state to constitute a control rod. When this control rod is mounted in a nuclear reactor to be heated to predetermined temp., high temp. solder 13 is melted to fill the tube 2 with liquid Na 11 to form the same constitution as a liquid metal sealed type control rod. When the operation of the nuclear reactor is further advanced, Na 11 is successively discharged to the outside from the hole 12 of the lower end plug 4 by the He gas 5 generated by the combustion of the pellet 1 and the tube 2 is perfectly filled with the gas 5 before long. The gas 5 is inferior to Na 11 in heat conductivity but the pellet 11 becomes thick in this stage by swelling to narrow the gap between the pellet 1 and the tube 2 and, therefore, the temp. of the pellet 1 is suppressed so as to be lower than the m.p. thereof. Therefore, the life of the control rod can be extended and the length thereof can be reduced.

Title: Control device for air-fuel ratio of engine
Inventor: TAKEBAYASHI HIROYUKI
IPC: F02D45/00
Filed: 1991-02-26
Abstract: PURPOSE:To improve responsibility to the slippage of a air-fuel ratio by determining whether learning value having learned before leaving a learning domain is used as it is or new learning value is established basing on the length of a time for which the control domain of the air-fuel ratio stays in a domain except the learning domain after leaving the learning domain. CONSTITUTION:A previously established learning domain is kept as a map, and learning value is computed on the slippage of the air-fuel ratio of an air-fuel mixture detected by an airflow sensor 20a and O2 sensor 26, and time having elasped after escaping after the learning domain until shifting to it again is measured. When the measured time is judged to be shorter than previously established time, a fixed air-fuel ratio control is executed using the learning value obtained by the previous judgement, and on the other hand, the longer a term having elasped after escaping from the learning domain until entering the learning domain again becomes, the more the frequency of the use of the learning value obtained by the previous computation is reduced. Finally the width of injection pulse is computed on the above learning value for giving a control signal to an injector 11, and the fuel conforming to the above value is jetted.

Title: System for determining orbit of spin type artificial satellite
Inventor: KOSAKA YUTAKA
IPC: G01S13/88
Filed: 1992-02-18
Abstract: PURPOSE:To improve the precision of doppler data and that of determining an orbit of an artificial satellite by filtering off a sinusoidal wave which is the factor of generated according to offsets of the antenna mount position in a spin type artificial satellite. CONSTITUTION:An orbit determining means 3 determines an orbit of an artificial satellite on the basis of distance measurement data 2 made up of doppler data 1 and the like. A sinusoidal estimating means 4 estimates a sinusoidal wave which is an error signal superposed on the doppler data 1 from a difference between the doppler data 1 and an orbit determined value determined by the orbit determining means 3 and filters off a sinusoidal wave estimated by the sinusoidal estimating means 4 from the doppler data 1 with superposed error signal. Doppler data with error signals filtered off serves again as the input data for orbit determination in the orbit determining means 3. Since an orbit can be determined by using doppler data including no large error signal, precision of orbit determination can be improved.

Title: Manual transmission
Inventor: KUKIHARA TAKEAKI
IPC: B60K23/02
Filed: 1995-01-10
Abstract: PURPOSE: To enable a vehicle to be driven forward up a hill simply by operation of two pedals by mounting a one-way clutch in the input-shaft system of a manual transmission. CONSTITUTION: A one-way clutch 1 has its outer ring secured to a nonrotating portion (transmission casing 2 and the like) and its inner ring secured to an input-shaft system (including an input-side main spindle or auxiliary shafts that are normally coupled to the main spindle, or a clutch shank). An output- shaft main spindle 4, even when exerted with rotational forces from the external, receives only an external force in the direction for rotating the input-side main spindle 3 in the proper rotation direction (rotation direction of prime mover); when the gear is in the neutral position, the output-side main spindle is free to rotate in any directions.  When the clutch 5 is released and the gear is engaged for forward motion, the vehicle cannot be reversed; i.e., the vehicle is prevented from reversing even without operation of the brake pedal and so can be started to move on a gradient simply by operating two pedals, i.e., the clutch and accelerator pedals after setting of the gear. If the gear is set for reverse, the vehicle can be reversed up a hill simply by operation of the clutch and accelerator pedals and is in no danger of moving forward.
