Title: Steering shaft lock
Inventor: SHIBAZAKI KAZUO
IPC: B60R25/02
Filed: 1979-10-23
Abstract: PURPOSE: To cause the turning manipulation of a steering handle incapable and prevent a car from being burglarized, by allowing the handling of extraction of a key to stop a lock lever into notched parts in a fixed member even if the steering handle is located at any position.  
     CONSTITUTION: At work of locking a steering shaft, if a key inserted into a cylinder lock A is successively moved turning from its on-position to lock-position and then extracted, a cylinder 3 is also shifted with the key by the amount of a clearance B simultaneously a rotor 8 is also moved backward. Then an engaging lever 15 provided in a slide cylinder 10 fixed to the rotor 8 is also simultaneously moved backward, and this causes the release of stopping a lever 5 to the engaging lever 15 thus the lever 5 is reset to the position as shown by a full line along a sloped face 8c of the rotor 8. Simultaneously with the above, a lock lever 6 is stopped to any of the notched parts 7aW7d in a fixed member 7 secured to a steering shaft 22 by a spring 18 thus to perform the lock work of the steering shaft 22.

Title: Operation of blast furnace
Inventor: NAITO MASAAKI
IPC: C21B5/00
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To improve the quality of molten iron by limitedly charging reduced iron having small grain diameter into the peripheral part of a furnace in the radial direction of the furnace to set high an ore/coke ratio by utilizing the reduced iron having small rain diameter, particularly the reduced iron having fine grain. SOLUTION: Into the peripheral part of the furnace in the radial direction of a blast furnace in which iron ore and coke are charged from the furnace top part and hot blast, etc. from tuyeres is blown to execute iron-making, reduced iron having small grain diameter is limitedly charged. The reason why the reduced iron together with the raw material iron ore are charged therein, is that the reduced iron is unnecessary to be reduced and can be charged into the peripheral part of the furnace. Further, the reason why the reduced iron is charged into the peripheral part of the furnace, is because the ventilation at the center part of the furnace is kept in a good condition and the center flow of gas into the furnace is promoted by raising the filling ratio of the reduced iron into the peripheral part.  The grain size of the reduced iron having small grain diameter is set to <=1/3 of the average grain diameter of the coke. This reason is because the ore/coke ratio is set to high by raising the filling ratio of the reduced iron and particularly, the reduced iron having fine grain of <=5 mm which can be imported at a low cost and can raise the filling ratio of the raw material, is used.

Title: Dc/dc converter
Inventor: ISHIKAWA HIROYUKI
IPC: H02M3/155
Filed: 1994-05-26
Abstract: PURPOSE:To perform DC-DC conversion with an improved power efficiency by operating a control circuit when supplying power to a heavily loaded circuit and stopping the operation of the control circuit when only a lightly loaded circuit operates for operating an oscillation circuit. CONSTITUTION:In the case of lightly loaded operation, a flip-flop FF19 is set to '1' and power is supplied to a ring oscillation circuit 7 so that the circuit operates. At this time, no power is supplied to a PWM control circuit 6 and hence the circuit 6 does not operate. When the voltage of an output terminal 4 is less than a reference output voltage, the output of a comparator 10 stops, a switch circuit 9 is turned on, and power is supplied to the ring oscillation circuit 7, thus turning ON/OFF a transistor 5 with a specific oscillation cycle and increasing an output voltage toward a reference output voltage. In the case of a lightly loaded state, the FF19 is reset and the output is stopped. The transistor 5 is switching-controlled by the PWM control circuit 6 and the voltage of the output terminal 4 is maintained to be a reference output voltage.

Title: Liquid crystal microcapsule and liquid crystal display element using the same
Inventor: IWANAGA HIRONORI
IPC: C08L101/12
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal microcapsule having a nature that its hue changes continuously by capsulating dichromatic dyestuff molecules and liquid crystal molecules by a high-polymer material and coloring this high-polymer material to the hue different from the hue of the dichromatic dyestuff molecules. SOLUTION: This microcapsule is formed by microcapsulating the dichromatic dyestuff molecules and liquid crystal molecules 2 by the high-polymer material 3 contg. isotropic dyestuff molecules 4. Namely, the microcapsule has the structure in which the liquid crystal phase dissolved with the dichromatic dyestuff 1 exists in the outside wall of the polymer consisting of the high-polymer material 3 colored to the prescribed color by the isotropic dyestuff. The microcapsule has the nature that its hue changes continuously as voltages are successively added. For example, substractive color mixing of yellow and blue is resulted and the display is black at the time of impressing the voltage in the case where the outside wall of the polymer is colored blue and the dichromatic dyestuff of yellow is used.  Further, the dyestuff molecules rise increasingly as the voltage is impressed and, therefore, the yellow weakens and the hue approximates continuously to blue.

Inventor: KOBAYASHI HIROYUKI
IPC: C23G1/14
Filed: 1990-05-25
Abstract: PURPOSE:To prevent the generation of the side-shift itself by washing the sheet to be rolled with the specific alkaline solution, at least, more than one time until the final pass. CONSTITUTION:On the manufacturing of the sheet metal that the metallic material 1 is cold-rolled and taken up to the coil state, the material to be rolled 1 is washed with the alkaline solution of >=pH 10 during 1-300sec, at least, more than one time until the final pass.

Abstract: PURPOSE:To prevent the breakage of a ceramic material when it is soldered on the electrode located on the main surface by a method wherein a plurality of electrodes, which are insulated with each other, are formed on the peripheral surface of a through hole. CONSTITUTION:A plurality of electrodes 14, which are connected with each other, are formed on the peripheral surface of the through hole 12 formed in the center of the ceramic material 11 to be used for a tabular varister. As an electrode 14 is formed on the peripheral wall of the through hole 12, the commutator of a small-sized motor can be connected to the electrode 14 located on the peripheral surface of the through hole. In this case, as the heat generated by soldering and added to the ceramic material 11 is radially transmitted to the outer peripheral side having a wide cross-section from the inner wall of the through hole 12, the heat is dispersed as it is transmitted to the outer peripheral side, and a sharp temperature gradient is hardly generated. As a result, the generation of cracks due to thermal stress can be reduced.
