Title: Continuous casting method for thin sheet
Inventor: ONISHI KUNIHIKO
IPC: B22D11/06
Filed: 1985-04-10
Abstract: PURPOSE:To eliminate the need for bending rolls and to decrease the height of an installation by forming twin molds to have different diameters, pulling a thin sheet in a curved state from between the twin molds and leveling the thin sheet to the state conforming to the horizontal direction by straightening rolls. CONSTITUTION:The twin mold rolls 2 and 3 are different in diameter but the peripheral speeds of both rolls 2, 3 are made the same and the wetting length of the rolls 2, 3 with a molten metal 10 is set the same. A dummy bar is inserted into the space between the twin molds 2 and 3 and the molten metal 10 is poured into a casting mold 1 from a tundish nozzle 5. The rolls 2, 3 are rotated and the thin sheet 7 is pulled from between both rolls 2, 3 by pulling downward the dummy bar. The peripheral speed of the rolls 2, 3 is made the same and the wetting length is set at the same length as well. The length and thickness of the shells formed on the rolls 2, 3 are therefore made the same and both shells are pressed to each other by the two rolls 2, 3, by which the thin sheet 7 is formed. Since the radii of both rolls are different, the thin sheet 7 is curved naturally at a radius R2 and is leveled by the straightening rolls 9.

CONSTITUTION:A spool 10B is inserted in such a manner as to freely slide against a spring 10L in a valve body 10A of a check valve 10. A land 10D for opening and closing a communicating hole 10C of passages L10 and L11 is formed on the forward end portion of the spool and the spring force of the spring 10L is set to a value such that resistance is not produced in oil in the passage L11 and it is smaller than oil pressure at the time of the lowest supply pressure during operation. A passage 10F is opened between the lands 10D, 10E, and a passage 10G for communicating the passage 10F with the spool trailing end opening portion. A check ball 10H is inserted in the passage 10G and pressed to a communicating hole 10K of the land 10E by a spring 10J. The pressing force is set in such a manner as to be opened by hydraulic force higher than hydraulic force produced by a difference in level between the valve 10 and a torque converter. Accordingly, when the supply amount of oil pressure is increased, the circulating amount is also increased.

Title: Ground injecting material
Inventor: JINBO SHUNJI
IPC: E02D3/12
Filed: 1994-03-23
Abstract: PURPOSE:To make adjustment of the gelation time easily by including a specified mount of silica sol as SiO2, blast furnace water crushed slag powder, lime, and setting adjusting agent in a ground injecting material. CONSTITUTION:4-180g silica sol as SiO2, 25-500g blast furnace water crushed slag powder, 1-50g lime, and 1-50g setting adjusting agent are included in the ground injecting material per liter. The slag powder promotes the long-term strength of the gelated substance of the injecting material containing it, while the lime acts in the injecting material as an alkali stimulating agent and commences the hardening reaction of the slag powder. The silica sol prevents sedimentation of the slag powder and undissolved lime in the injecting material and turns the material into gel form with its composition kept uniform. while the setting adjusting agent retards the gelation rection arising between silica sol and lime. An injection solution containing the silica sol and the setting adjusting agent is adjusted separately from adjustment of a slurry containing the slag powder and lime and the solution and slurry are mixed together at the tip of a double structural tube, to form a ground injecting material which is then injected into the ground.

Title: Liquid crystal optical element
Inventor: KANBE JIYUNICHIROU
IPC: G02F1/1335
Filed: 1984-04-16
Abstract: PURPOSE:To enable attainment of a certain specified bistable state by subjecting the surface of a substrate to an adequate uniaxial orientation treatment. CONSTITUTION:SmC* of the monodomain having a non-spiral structure is obtd. if the thickness, for example, of a cell is made about <=3mum by phase transition from SmA to SmC* in the process of decreasing temp. The liquid crystal molecules in the SmA phase are oriented in the average molecular axis direction 501 of the liquid crystal coincident with a rubbing direction 500. The average molecular axis direction of the liquid crystal molecules in the SmC* phase inclines toward the direction 502 and the average molecular axis direction 502 of SmC* inclines at an angle theta with the rubbing direction 500, thus having the 1st stable orientation state. If a voltage is impressed to the upper and lower substrates in this state, the average molecular axis direction of the liquid crystal molecules of SmC* changes to the angle larger than the angle theta and attains the satd. third stable orientation state at an angle H. The average molecular axis direction in this state is designated as 503. When the voltage is returned to zero, the liquid crystal molecules restore again the state of the original 1st molecular axis direction 502.

Abstract: PURPOSE: To make it possible to conduct optical measurement of an object by turning its required region into a multi-crystal in such a manner that an insulator is formed on the required region on a base plate prior to formation of an epithaxial layer.  
     CONSTITUTION: An insulator layer (e.g. an approimately 500Å thick film 5 of SiO 2 ) is formed on a required region on the top surface of a base plate 4 made of such a material as phosphoric silicon. And then, an n type epithaxial layer 6 is formed. At this time, although the n type epithaxial layer 6 on the region free of SiO 2  film is a single (or mono) crystal, the n type epithaxial layer 7 on the SiO 2  layer is to become a multi-crystal. Now, the multi-crystal n type epithaxial layer 7 is selectively removed by using a mixed solution of fluoric acid and nitric acid. And then, the SiO 2  film is removed by using fluoric acid. Now, measurement is made on difference in height between thus exposed surface of the phosphoric silicon base plate 4 and the surface of the single- (or mono-) crystal n type epithaxial layer 6.
