Title: Terminal hot-water supplying device in immediate hot-water supplying system
Inventor: UEMATSU HIDEO
IPC: F24D17/00
Filed: 1985-02-27
Abstract: PURPOSE:To permit to supply hot-water immediately and economically in a central hot-water supplying by a method wherein a control valve, an adjusting valve and a hot-water reserving tank are communicated mutually and systematically. CONSTITUTION:When the control valve 7 (hot-water side valve 5 and water side valve 6) is opened in winter, for example, water of temperature 5 deg.C, stagnated in a hot-water supplying pipe 3, pushes up a non-return valve 11, provided at the lower part of a hot-water reserving tank 15, and flows into the lower part of the tank 15. High-temperature water of 85 deg.C is pushed up to the upper part of the tank 15 and comes out through a hot-water conduit 13. The hot-water is mixed with cold water, comes out through a bypass pipe 19, at primary mixing point 20 and the temperature thereof becomes 45 deg.C. When cold water, whose volume corresponds to the 1/2 of the reserving capacity of the tank 15, flows into the tank 15, high- temperature water comes from a hot-water supplying heat source device 1 to the bypass pipe. In this case, the cold water of about 5 deg.C, delivered from the hot-water conduit 13, is joined with the hot-water of 85 deg.C from the bypass pipe at the primary mixing point 20 and the temperature thereof becomes about 45 deg.C. Accordingly, the hot-water is mixed automatically with the cold water from a water supplying pipeline 4 so as to obtain a predetermined temperature at secondary mixing point 21 in either case if the temperature setting of the adjusting valve 10 is lower than 45 deg.C when the hot-water is used at first.

Title: Lid with hot water draining hole for instant food container
Inventor: YOSHINAGA MASANOBU
IPC: A23L7/113
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To reliably peel a lid from a container without a composite sheet broken from half cuts for forming a hot water draining hole when the lid is completely peeled off from the container by laminating a plastic film layer on the composite sheet. SOLUTION: A composite sheet 1 comprises a sealant 2, a gas barrier layer 3, a plastic film layer 15 and an extruded thermoplastic resin layer 4 which are laminated sequentially from an internal face of a container. The constitution can increase tear strength of the composite sheet 1 by laminating the plastic film layer 15, so that a lid A when peeled may not be broken from half cuts for forming a hot water draining hole. Particularly, by using a stretched film as the plastic film layer 15, tear strength can be further improved, whereby the layer 15 can be thinner and a cost may not be much increased.

Title: Waste heat unit desk equipped with cooling device
Inventor: MIYAUCHI ATSUSHI
IPC: F24F1/02
Filed: 1988-02-19
Abstract: PURPOSE:To obtain a pleasant cooling air without disturbing a cooling air zone, by sending waste heat air to a waste heat accumulator by way of a waste heat air suction port and discharging the waste heat air upward behind the top board of a desk from a waste heat air discharge port. CONSTITUTION:When electricity is supplied to a cooling air blasting machine 8, an indoor air is cooled by an evaporator 3, and the cooled air is sent to a cooling air accumulator 9 by way of a cooling air nozzle 13 by the action of a cooling air blower 6. A wind velocity is equalized within the cooling air accumulator 9, where the air is turned into a cooling air, which is sent from an cooling air discharge port 11, thereby forming a cooling air zone above a top board 2. Waste heat air 18 is sent into a waste heat accumulator 10, passing through a waste heat nozzle 17. The pressure of the waste heat air 18 is reduced within the waste heat accumulator 10 and is equalized as the wind velocity is reduced. Then, a unified low speed waste heat air 18 rises naturally from a waste heat air discharge port 15 upward behind the top board 2. It is, therefore, possible to obtain a pleasant cooling air without increasing the cooling air zone above the top board.

IPC: G03G15/04
Filed: 1979-03-31
Abstract: PURPOSE: To make pressure plate body stoppable at a desired turning angle by using compression springs which permit desired changing of compression amounts.  
     CONSTITUTION: A slider 4 provided at fulcrum axis 2 is provided with compression springs 41 and is pressed toward the fulcrum axis center. Adjust screws 42 are screwed to the fulcrum axis screw parts 21. Then, when the pressure plate body 1 is pushed upward, a pushup link 71 tilts with respect to a pushout link 5 and turns about a pressure axis 7. At the same time, the pushup shaft 62 receives the elastic force of the compression springs 41 by way of the pushout link 5 and is thereby turned upward about the fulcrum axis 2. It stops in the position where its own weight and the moment by the pushup link balance. If the amount of contact or spacing of the pushup link 5 with or from the fulcrum axes 5 is adjusted by an adjust screw 42, the angle α of turning is adjusted.
