Title: Apparatus for cooling reticle mask
Inventor: HONGO TOSHIAKI
IPC: G03F7/20
Filed: 1988-03-31
Abstract: PURPOSE:To prevent thermal expansion of a reticle mask for improving the patterning accuracy and to improve finess of circuit patterns, by providing a cooling space between a reticle mask and a reticle mask cover and supplying a cooling medium into the cooling space for removing heat generated by the reticle mask. CONSTITUTION:A cooling space 7 is defined by a reticle mask cover 4, a reticle mask 5 and a retainer 6. An inlet 7a for supplying a cooling medium such as gas or the like is provided on one side of the retainer 6, while an outlet 7b is provided on the opposite side. A cooling medium supply 8 for example consists of a pump 9 for discharging air, a filter 10 for cleaning the air, a valve 11 for adjusting flow rate of the air and an adjusting system for adjusting flow rate and temperature. When predetermined circuit patterns are transferred while a semiconductor wafer 14 accommodated in a reaction chamber is exposed to a high-energy laser beam, the cooling medium is continuously supplied so as to contact with the reticle mask 5. In this manner, even if the reticle mask 5 irradiated with the laser beam generates heat, such heat can be discharged effectively and distortion due to thermal expansion can be prevented.

Title: Manufacture of decorating molding
Inventor: MORISHITA NATSUKI
IPC: B32B27/12
Filed: 1995-03-31
Abstract: PURPOSE: To prevent the defective product due to casting of a melted thermosetting molding material by using a thermosetting material which contains a thermosetting resin and a polyamide to heat to compression mold by superposing a decorating sheet and the molding material. CONSTITUTION: A decorating molding uses a thermosetting resin and a polyamine as a thermosetting molding material 12 to heat to compression mold by superposing a decorating sheet 11 and a thermosetting molding material 12 in a mold. The material 12 is cast to the sheet 11 by casting the molding material resin melted to be decreased in viscosity in a slight gap between the end of the sheet 11 and the mold. Then, as the thermosetting molding material, the thermosetting resin containing the polyamine is used to raise the melted viscosity of the material 12 at the time of molding, and the resin fluidity is reduced. Thus, the molding material resin scarcely flows into the gap between the sheet 11 and the mold.

Title: Heat-proof soft gasket
Inventor: YAMAMOTO TSUTOMU
IPC: F16J15/14
Filed: 1980-06-06
Abstract: PURPOSE: To provide a heat-proof soft gasket which adopts material formed by compounding a rubber latex with a scalelike thin particle stripped from an expansion vermiculite, so that it will not lose strength or elasticity even more than 400°C.  
     CONSTITUTION: A hydrated composition sheet is formed by using stripped thin particles 1 of expansion vermiculite for principal material and adding a rubber latex thereto. When the sheet is in a moist state, rubber particles 3 existing with water between vermiculite scalelike thin particles 1, 1 is still in the form of a latex. Then, the sheet is compressed to bring the rubber particles 3 into contact one another. After that, the sheet is dried to evaporate moisture 2. Thus, the rubber particles 3 are deformed to begin to adhere one another. At last all the rubber particles adhere to melt into one another and to form itself into a film after the boundary between the rubber particles 3, 3 disappears.

Title: Method for stepping motor driving
Inventor: SASAKI NAOTAKA
IPC: H02P8/00
Filed: 1992-02-05
Abstract: PURPOSE:To make it possible to prevent the degradation of throughput of a motor, when moving to a constant velocity period at an intermediate point in an acceleration period before reaching the maximum velocity, by running a motor in such an acceleration/deceleration pattern that the length of the constant velocity period differs from those of other constant velocity periods. CONSTITUTION:For cases where a motor moves to a constant velocity period at an intermediate point in an acceleration period to the maximum plotting velocity in short vector plotting by an X-Y plotter, the normal length of the constant velocity period is (t3-t1), and an acceleration/deceleration pattern of P1 is employed. In proximity to the attainment velocity V2 in an acceleration/ deceleration pattern of P2, the operation locus is vibratory much more than usual; therefore, the length of the patterns are so set that (t3-t1)<(t5-r2). This makes it possible to move from a constant velocity period to a deceleration period without being influenced by the residual vibration of the vibration generated at time t2.
