IPC: G03F1/40
Filed: 1981-12-28
Abstract: PURPOSE:To obtain a glass mask for patten printing use, free from attached contaminants, in high yield, by immersing the glass to be cleaned in an acid such as sulfuric acid, and subjecting the glass to the conventional water-washing, alcohol washing, vapor cleaning, and antistatic treatment. CONSTITUTION:A glass mask to be cleaned is immersed in hot concentrated sulfuric acid or mixed acid at about 50-110 deg.C for about 5-10min (10), and drained thoroughly. The mask is then washed with water (1A) e.g. by immersing in water, etc., and washed with alcohol (2) e.g. by immersion, etc. The next vapor cleaning process (3) is carried out by contacting freon vapor to the surface of the glass mask to effect the condensation of the freon to the whole surface of the mask, and evaporating and drying the condensed freon. An antistatic  treatment (4) is applied to the surface of the glass mask.

Title: Program debug system
Inventor: HAKUBA TADANOBU
IPC: G06F11/28
Filed: 1985-09-24
Abstract: PURPOSE:To improve the program debugging efficiency by outputting automatically the contents of a register in an address stopping mode with no intervention of an operator therefore eliminating the miscollection of the register information in a program debugging mode. CONSTITUTION:When an operator supplies a command through a console CSL3, a stop address is written by a monitor program 50 and a processing program 60 is executed. Thus an address stop interruption is produced. In an interruption mode the contents of a register of the program 60 are stored in a prescribed area of a main memory MMU 11 then the control is shifted to the interruption processing 51 within the program 50. The control is shifted to the address stop processing 52 to deliver the instruction address stored in the MMU 11 to the console CSL3 after the processing 51 detects an address stop interruption. Thus the stop address is informed to the operator.

Title: Grain washing device
Inventor: TOKUNAGA NAOKI
IPC: A47J43/24
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To easily set washing work by arranging a jacket having a cylindrical net in a tank lower end part and a see-through pipe to communicate freely ascendable-descendable discharge rice valve with the jacket on the outside. SOLUTION: Water at washing time enters a pipe 5 from a jacket 3. Therefore, an operator can easily know a stained condition by visually observing the water housed in the see-through pipe 5, and washing can be easily set. Then, an opening-closing valve 15 advances, and closes a waterway 13, and a prescribed quantity of fresh water is supplied to a tank 1 by a water supply means. At this time, partial fresh water enters the pipe 5 through the waterway 13, and next, since an ascending-descending shaft 21 descends up to a prescribed position by a driving means, a rice discharge valve 4 alse descends, and releases a rice discharge port 22. Then, water and rice stored in the tank 1 fall, and are housed in a lower inner iron pot. The fresh water housed in the pipe 5 falls later on the rice discharge valve 4, and washes off sticking rice.  Therefore, when the rice discharge valve rises again, since a clearance is not generated by the rice, the occurrence of water leakage can be prevented.

Title: Combined cycle generating plant
Inventor: OONUKI TOSHIO
IPC: F01K23/10
Filed: 1982-12-02
Abstract: PURPOSE:To improve heat efficiency while to remove oxygen dissolved in supply water by providing return and supply water bypass systems in a heat exchanger for heat exchanging between return and supply water thereby controlling the temperature of supply water to a waste heat recovery boiler properly. CONSTITUTION:When employing fuel containing no sulfur in a gas turbine plant, it is constructed such that return water of steam turbine plant 11 will pass through a heat exchanger 40. Consequently supply water heated over 100 deg.C in a deaerator 37 will be heat exchanged with return water in the heat exchanger 40 and cooled to lower the temperature of supply water thus to lower the exhaust gas outlet temperature of waste heat recovery boiler 18 resulting in improvement of heat efficiency of plant. When employing fuel containing sulfur, heat exchanger 40 is not used where return water is led through a bypath system 44 while supply water is led through a supply water bypath system 52. Since heat exchange is not performed between return and supply water, saturated temperature of supply water from deaerator 37 will become supply water temperature to said boiler 18 enabling high temperature water supply higher than 100 deg.C.

Abstract: PURPOSE:To perform the maintenance of a telephone exchange without lowering a service to a subscriber by enabling outgoing from the subscriber or incoming to the subscriber to be performed even in executing a test, by substituting a circuit for a subscriber circuit to be tested by using a spare subscriber circuit. CONSTITUTION:When a maintenance engineer instructs the test of the subscriber circuit 3 by inputting a command, a subscriber circuit controller 5 checks the state of a subscriber line 2 by the indication of a central control unit 7, and connects the subscriber line 2 to the spare subscriber circuit 4 by switching a switch 8 to a contact 11 in a null state, and the central control unit 7 issues an instruction to connect the subscriber circuit 3 and a subscriber circuit test device 6 to the subscriber controller 5 by a switch 9. Also, when the subscriber line 2 is used, the central control unit 7 issues the instruction to interrupt the test to the subscriber circuit test device 6. Thus, the test of the subscriber circuit 3, etc., is performed by using the spare subscriber circuit 4 when the subscriber line 2, etc., is set at the null state. In such a way, it is possible to perform the maintenance of the subscriber circuit without lowering the service for the subscriber.
