Title: Pellicle
Inventor: NAGAMURA YOSHIKAZU
IPC: G03F1/62
Filed: 1994-09-09
Abstract: PURPOSE: To make it possible to prevent foreign matter from falling onto a photomask surface from the inner half surface of a projecting surface formed atop the frame of a pellicle by applying adhesive on the outer half surface of this projecting surface. CONSTITUTION: An adhesive 13 is applied on the inner half surface of the projecting surface 12a of the frame 12. A pellicle film 11 is adhered to the frame 12 with this adhesive 13. If the foreign matter is generated from the adhesive 13 by vibration of the pellicle film 11, this foreign matter is provented from infiltrating the inner half surface side of the projecting surface 12a and falls onto the outer side of the pellicle 14 along the outer half surface and, therefore, the fall and adhesion of the foreign matter on the photomask do not arise. Since the shape of the front surface of the frame 10 is merely necessitated to be changed, the inexpensive pellicle is provided without an increase in the labor for manufacture.
Patent JP-S6373092-A (JP)
Title: Heat exchanger
Inventor: FURUE TOSHIKI
IPC: F28D15/02
Filed: 1986-09-16
Abstract: PURPOSE:To effectively prevent a low temperature corrosion by connecting heat transfer tubes having a possibility of producing the low temperature corrosion, of heat transfer tubes constituting an evaporation tube group, to each other by a medium circulation system separate from other heat transfer tube group, and closing the medium circulation system of the heat transfer tubes upon lowering of the temperature of a heating gas. CONSTITUTION:A plurality of stages of heat transfer tube panels PA are arranged within a duct 1 through which a heating gas 17 passes in the shifting direction of the heating gas. When the measured temperature of the heating gas 17 becomes lower than a predetermined value, and a possibility of producing a low temperature corrosion is produced in heat transfer tube panels PA1 and PA2, a temperature controller 14 closes valves 12a and 12b and stops the supply of a heating fluid to a liquid lifting heater. Thus, air bubbles are not produced from a medium in a liquid connecting tube, and the circulation of the liquid is stopped. Accordingly, since the heat absorption in the heat transfer tube panels PA1 and PA2 is stopped, the surface temperature of heat transfer tubes constituting these heat transfer tube panels is kept at a value higher than a predetermined value, thus preventing the low temperature corrosion.

Title: Motor control circuit
Inventor: NAKANO TAKUSHI
IPC: H02P7/293
Filed: 1990-08-16
Abstract: PURPOSE:To control the position of a motor with the least digit accuracy of a rotary encoder and to improve the resolution by using the rotary encoder as a rotational angle/speed sensor and feeding back the information on the rotary encoder. CONSTITUTION:An optical rotary encoder 2 is connected to a rotary shaft of a DC motor 1 and outputs 4096 rate pulses RP and a single position pulse PP per revolution of the rotary shaft. The control signals (PC, TP) given from a despun control part are inputted to a position error detection part 3 in addition to the pulses PP and RP. A frequency change applying circuit 4 outputs a clock having a frequency of half as much as a standard spin clock SC of the pulse RP when a position error (u) is equal to zero. However the circuit 4 outputs a clock having a frequency increasing or decreasing in proportion to the error (u) when this error is not equal to zero. Thus the error (u) can be fed back.

Abstract: PURPOSE:To realize a compact and light synchronizer ring, to lower a cost and to make a transmission compact by making the width to an axial direction of the synchronizer ring for an end step gear smaller than the width to an axial direction of the synchronizer ring for an intermediate step gear. CONSTITUTION:The width to an axial direction of a synchronizer ring for the end step gear of synchronous engaging devices respectively provides at both the sides of a single synchronizer sleeve is made smaller than the width to an axial direction of a synchronizer ring for an intermediate step gear.
