Title: Multi-blade fan
Inventor: SUZUKI KENJI
IPC: F04D29/66
Filed: 1987-04-10
Abstract: PURPOSE:To prevent a blade from decreasing its strength, by folding one end of a balance weight, formed into a U-shape, to be flexed to the inside in a position wider than a width of the blade and fixed to it by calking. CONSTITUTION:A balance weight 7, which forms a metal plate into an almost U shape, is mounted by calking to a blade 6 of a multi-blade fan 5. The balance weight 7, folding its point end to be curved in a position of size a little longer than a width of the blade 6, forms a fold 7a and a pawl 7b. The balance weight 7, holding its fold 7a, is inserted into the blade 6 and fixed to it by calking. Accordingly, the blade is prevented from decreasing its strength because of no necessity for providing a particular notch or the like in the blade.

Filed: 1993-04-14
Abstract: PURPOSE:To standardize a process analysis chart, and to shorten the preparing time of the process analysis chart by retrieving and reading process analysis data belonging to a desired parts group from the process analysis chart selected from among the stored process analysis charts. CONSTITUTION:A controller 1 prepares the process analysis chart by editing the process analysis data inputted from a keyboard 2 and a mouse 3, and stores the process analysis chart in an outside storage device 6. Then, one desired process analysis chart is selected from among the process analysis charts by the keyboard 2 and the mouse 3, and when a condition that the process analysis data belonging to the desired parts group are retrieved from the selected process analysis chart is designated, the controller 1 retrieves and reads the process analysis data from the outside storage device 6 based on the retrieving condition.

Title: Hot water feeding tank
Inventor: SATO HIDEAKI
IPC: B60S1/50
Filed: 1987-04-09
Abstract: PURPOSE:To reduce the degree of holding heat of hot water in a tank being taken out to the tank outside by heat conduction by installing the passage extension part interposed in a cooling passage at a vacuum clearance sorrounding a relatively long hot water running passage and an adiabatic area in a double wall. CONSTITUTION:If a heater 10 is made to work after cooling water is filled up in a tank A from a cooling water passage 4, water inside the tank A is heated and thereby its specific gravity becomes lighter, thus high temperature water is stored in a top wall surface nearby. At time of use of hot water, if cooling water is supplied into the inside of the tank A from the cooling passage 4, upper hot water is thrust into this pipe from an upper opening end of a hot water running passage 3, and it flows to the outside from a hot water takeout port 7. And when cooling water feed is stopped, it is heated up to the specified temperature by the heater 10. Thus, in the hot water stored in the tank A, the degree of its holding heat inside the tank A is sharply reducible from being taken out to the outside of the tank A by conduction, owing to the presence of the passage extension part 4A interposed between a vacuum clearance (a) surrounding the relatively long hot water running passage 3 and the cooling passage 4 at an adiabatic area in a double wall.

Title: Charge pump circuit
Inventor: HAYASHI TOMOHIRO
IPC: H03L7/095
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a charge pump circuit capable of holding balance between charge and discharge and suppressing the occurrence of a delay between two input signals. SOLUTION: A capacitor in a charge pump 2 is charged with electricity by an UP signal 12 outputted from a phase comparator 1 and a capacitor in a charge pump 3 is charged with electricity by a DOWN signal 13. Difference voltage between terminal voltage levels of both the capacitors is calculated by a subtractor 7 and outputted. Since both the UP signal and DOWN signal are used for charging the capacitors in the charge pumps 2, 3 and discharge is executed by an external CLR signal, charge and discharge are not unbalanced due to the inversion of the UP signal and the DOWN signal. An inverter for inverting the DOWN signal is made unnecessary and no delay is generated between two input signals.
