Title: Crusher
Inventor: SONE YASUSHI
IPC: A47J42/26
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To enable the packing of a crusher to be securely mounted on a bottle bed and the cutting performance from lowering by forming a spiral rib tilting in a direction the same as that of a screw part of the bottle bed onto a face facing the packing outer periphery side of a groove. SOLUTION: When part of a packing 12 is not engaged with a rib 14 by insufficient pushing, etc., part of the packing 12 is disengaged when the bottle bed is turned over. Since the inclination of the rib 14 of a groove 11 is formed almost the same as the inclination of a female screw 9 of the bottle bed 5, the packing 12 is rotated together with the vessel 15 to be completely set in the groove 11 as the bottle bed 5 and the vessel 16 are screwed together and the rib 14 is engaged with the whole circumference of the packing 12 to securely hold the packing. In the condition the packing 12 is set in the groove 11, since no gap exists in between the inner circumference of the packing 12 and the groove 11, no cut material cannot comes in to prevent rough cutting. Thus the cutting performance is prevented from lowering.

Title: Skid control device by use of microcomputer
Inventor: TAKAHASHI JIYUNICHI
IPC: B60T8/66
Filed: 1979-02-16
Abstract: PURPOSE: To realize optimum braking by making ROM store two kinds or more of skid control patterns corresponding to every slip rate obtained by preliminary testing so as to enable skid control corresponding to each slip rate on conducting skid control.  
     CONSTITUTION: An output signal from a wheel velocity sensor 9 is stored in RAM3 through I/O port 4 so as to be compared with the next signal from the sensor 9. The occurence of skid is judged by MPU1 in comparison with the value stored in ROM2. When any skid is detected, MPU1 computes constantly the slip rate according to a pair of values of the velocity of wheel taken in at all times and determines to which damping straight line on the road surface stored in ROM2 the slip rate obtained through computation corresponds. Based on the slip rate thus obtained, it operates an actuator 6 through I/O port 4 operating further a hydraulic control device 7 for braking.

Filed: 1988-01-27
Abstract: PURPOSE:To make it possible to utilize a LB membrane as a high-performance element, by irradiating light or heat wave of belt shape against a monomolecular film on a subphase and moving the position of irradiation so as to turn the monomolecular film into a monodomain membrane. CONSTITUTION:Light or heat wave of belt shape is irradiated against a monomolecular film 7 on a subphase such as water, wherein, for example, a heat wave is irradiated by means of an infrared radiation device 3. By moving the position of the irradiation, a monomolecular film consisting of a number of domains 7 having crystal orientations different from one another is turned into a monodomain 8 whose crystals are highly regulated. LB membrane of the monodomain 8 has neither crack nor pin hole, and has uniform light reflectivity and response characteristic for external impulse, hence it can be applied to various functional elements requiring high accuracy.

Title: Reflective protection film for replica diffraction grating
Inventor: RICHARD G MORTON
IPC: H01S3/08
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To improve the conventional process and extend the service life of a replica diffraction grating by removing a replica from a master diffraction grating to clean it and adding a step for laminating a thin film reflective protection film made of aluminum on its surface. SOLUTION: In added step, an aluminum thin layer 34 is formed on the surface of an aluminum layer 22 by sputtering or vopor-deposition in a vacuum reaction chamber. The thickness of the aluminum thin layer 34 is preferably about 100nm enough to prevent the deterioration of an epoxy layer 24 due to cracks 30 and 31 of the lower aluminum layer 22. Therefore, the existing crack in the aluminum layer 22 is covered and filled with the layer 34. Since a protection film formed of aluminum layer 34 is coated after the completion of production of replica, no influence of external force damaging the protection film is given and untraviolet-ray shielding effect can be maintained.

Abstract: PROBLEM TO BE SOLVED: To efficiently mix a main component gas with the second component gas and accurately maintain the mixing ratio of both the components at a set value, when the main component gas is mixed with the second component gas and then charged into a burner. SOLUTION: A main component gas prepared by evaporating a raw material for silica glass is mixed with the second component gas, etc., at the connection portions of lines. Especially, the connection portion wherein the flow of the main component gas is less than that of the second component gas is formed in a double pipe structure wherein the small diameter connection portion K of the main gas pipe is inserted into the central portion of the large diameter connection portion H of the second component gas pipe. The main component gas is blown out toward the cross-sectional center of the second component gas pipe to enhance the efficiency of the mixing.  Temperature-controlling devices for preventing the coagulation of the gases in the lines are controlled by a PID control method, thereby preventing such the disorder of a mixed component ratio caused by the volume expansion or contraction of the gas as by an ON- OFF control method.
