Abstract: PURPOSE:To efficiently obtain large-sized sheet glass products having high quality by providing an accumulating chamber between a melting chamber and a working chamber and setting the base of the accumulating chamber at the same height as the top end face of the weir of the operating chamber or above. CONSTITUTION:The melting chamber 2, the accumulating chamber 4 and the working chamber 5 are disposed in this order and the weir 20 for taking out a glass melt 34 is provided at the top end of the rear part wall of the working chamber 5. Further, a glass flow rate controller 23 is provided between the accumulating chamber 4 and the working chamber 5 and the base of the accumulating chamber 4 is disposed at the same height as the top end face of the weir 20 or above. Glass raw materials are charged into the melting chamber 2 from a glass raw material supply device 6 and are heated by a gas burner 11 to form the glass melt 31. The glass melt is introduced through the stirring chamber 3 into the accumulating chamber 4 and is accumulated. The accumulated glass melt 33 is then introduced through the working chamber 5 into the molding device, by which the glass melt is molded to the glass plate. As a result the glass melt 33 to be admitted to the working chamber 5 remains in the accumulating chamber 4 and the degradation in the quality is prevented.

Title: Logic circuit chart restoring method
Inventor: OE RYOICHI
IPC: H01L21/027
Filed: 1987-06-10
Abstract: PURPOSE:To facilitate the comparing collating of an original logic circuit chart and a restored logic circuit chart by obtaining a route whose logical gate number is a maximum as a main route and arranging the respective logical gates of the main route on one line along the flow of a signal. CONSTITUTION:By the connection information of a logical gate, the respective logical gate numbers of each route from an external unit terminal 1 to external terminals 2 and 9 are counted and the route whose logical gate number is a maximum is determined as a main route. Next, the respective logical gates 3, 4, 6 and 8 of the main route are arranged on one line along the flow of a signal. The respective logical gates of the rest besides the main route are successively added to the routes already arranged and arranged. Thus, the arrangement of the logical gate where the signal reverses is prevented and a restored logical circuit chart same as an original logical circuit is obtained. Accordingly, the comparing collating of the both is facilitated.

Title: Water heater with hot water mixture controller
Inventor: TSURUTA TORU
IPC: F24H1/10
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent overshoot or undershoot of mixture hot water temperature in re-outputting mixture hot water, by altering a target distribution ratio of the mixture hot water in the case of supplying or stopping the mixture hot water by an operation of a hot water supply terminal in response to a flow rate of the mixture hot water before stopping. SOLUTION: A stepping motor M is controlled according to a set temperature Ts, detected value Th of heat exchanger temperature sensor 27 and detected value Tc of input water temperature sensor 23. When a hot water supply cock 1 is closed from an open state so that the water supply is being stopped, a target distribution ratio Rf is calculated by a formula Rf=(Ts-Tc+a)/(Th-Tc), where the letter a indicates a variable decided by flow rate change ratio at the time of the stop of the water supply and water supply amount immediately before the water supply is stopped. The change ratio can be calculated by a change of a detected value of a water amount sensor 25 per predetermined time, and the water supply amount immediately before the stop of the water supply is detected by the sensor 25.

Abstract: PROBLEM TO BE SOLVED: To provide effective chip pockets simultaneously with manufacturing by projecting the extreme end part of an abrasive grain from bonding agent by a specific size. SOLUTION: A grinding layer forming part is provided with walls on the inner circumferential side and on the outer circumferential side, and hence a groove is formed. Molten mixed liquid is flowed in the groove extending over the full circumference. A leveling plate is laid over the upper faces of the walls on the inner circumferential side and the outer circumferential side, and is rotated over one rotation on the circumference as it is so as to level the liquid to remove surplus molten mixed liquid outside the walls. Hereby, a mixed liquid layer of uniform thickness is formed in the groove in the depth direction. This depth is favorable to be less than about two times, more favorably less than about 1.2 times the maximum diameter of the abrasive grain.  Hereby the abrasive grain projects more than 2 μm from the bond, and the height of the extreme ends of many projecting abrasive grains are nearly arranged in order.

Title: Microprogram control unit
Inventor: ONO TOSHIYUKI
IPC: G06F12/16
Filed: 1979-11-09
Abstract: PURPOSE: To reduce occurrence of the error in the control storage, by detecting the bit error of the control storage as well as the correction frequency and then performing a rewriting for the control storage.  
     CONSTITUTION: In case an error due to the disturbance or the like occurs, the control storage CST performs the correction of error. The correction working circuit EBC sends one unit of pulse to the counter CNT with every correction given from the CST. The counter CNT continues its counting action and then produces the overflow signal OFS when the count value exceeds the prescribed frequency. On the other hand, the microprogram reading device MPG confirms from an analysis of program that no action occurs in the near future to the storage CST, and then sends the idle state signal WTS to the AND circuit AD. The logic product output of the signals WTS and OFS is turned into the restart signal of the loader LDR to rewrite totally the contents of the CST. In such way, the error occurrence can be reduced for the CST.
