IPC: A47J31/00
Filed: 1991-12-25
Abstract: PURPOSE:To enable the uniform extraction of tea by arranging a hot water storage tank, a pump, a connecting tube, a bend part and a suction tube. CONSTITUTION:A fixed time pump 3 runs by the operation of a tea supply switch set on an automatic tea feeder and a constant amount of hot water is delivered out through a first connecting tube 4 from a hot water storage tank 1. The hot water delivered from the pump 3 is poured to a tea filter 8 from a trickling port 7 through a bend 12 of a second connecting tube While a part of the hot water is returned to the water storage rank 1 with a suction tube 13 linking the bend 12 of the second connecting tube to the hot water storage tank 1, thus a constant amount of the hot water is supplied to the tea filter 8. The tea filter 8 enable the putting of a constant amount of tea into a cup 14 through a funnel 11 with the pouring of a high temperature hot water from the tricking port 7 as it is previously supplied with tea leaves by a tea leaf feeder 10. This allows the uniform extraction of tea thereby supplying tasty tea.

Title: Operation device when operation switch is at fault
Inventor: MIZUNO KUNIO
IPC: G06F3/02
Filed: 1989-12-28
Abstract: PURPOSE:To obtain safety even if normal/inverse switches are adhesively at fault in an air-conditioning controller for automobile by permitting a fault judgement means to output a fixed output when both are fixed, and a switch output through the use of the other normal/inverse switch when one is fixed when the normal/inverse switches are depressed but they are not restored and they are adhesively at fault. CONSTITUTION:Two normal/inverse switches 54a and 54b whose outputs continuously change in an increase or decrease direction if they are continuously depressed, and a fault judgement means 200 which judges fixation from the depressed state of two normal/inverse switches 54a and 54b and which decides whether it is in one switch or two switches are provided. If it is in both as the result of decision in the fault deciding means 200, the prescribed adhesive output is outputted, and the switch output is outputted by one remaining switch if it is in one. Thus, the switch output can be changed by the operation of one switch when the fault is in one switch even if two normal/inverse switches are at fault in the air-conditioning controller for automobile.

Title: Heating resistor type air flow measuring device
Inventor: WATANABE IZUMI
IPC: G01F1/68
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a device, in which increase and decrease of signal are offset and the generation of change of the signal is prevented even in the case where moisture is changed and the generation of lowering of accuracy is prevented, by using nylon group resin material. SOLUTION: A nylon resin 9 is used for a member, which forms a main passage 1. The nylon resin 9 allows a large dimensional increase, and water absorption rate and dimensional change thereof are proportional to each other. As a nylon resin 9, nylon 6, nylon 66, nylon 6-glass fiber at 30%, and nylon 11 are used, and generally, normal chain high polymer, which is polymerized by amide connection (-NHCO-), is used. Cross sectional area of the nylon resin 9 is increased at about 4% at 80% of moisture, allowing existence of some difference in response to the kind of resin. Since flow speed of the air, which flows in the main passage 1, is reduced by increase of the cross sectional area, flow speed of the air, which flows in an auxiliary passage 2, is reduced, and flow to be detected by a heating resistor element 3 is reduced.  Since these two phenomenon offset each other, change of the characteristic can be prevented.

Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a shutter for a camera advantageous in power consumption or the like, in the case of releasing respective lockings of driving members for a front blade and a rear blade with a shape memory alloy. SOLUTION: When a power is supplied between both ends of the wire-like shape memory alloys 10 and 11, the alloys are shortened and the driving member for a front blade 2 and the driving member for a rear blade 3 are actuated to set positions. The set state of the members 2 and 3 is kept by locking the actuation pins 2a and 3a to the hook parts 20a and 21a of a locking member for a front blade 20 and a locking member for a rear blade 21. In the case of photographing, the power is supplied to both ends of shape memory alloys 24 and 25 to release the locks of the members 20 and 21 in a stage where electromagnetic 36 and 37 attract and hold iron piece members 4 and 5 in attracted states, so that the exposure actuation of the members 2 and 3 is made possible. After releasing the locking, the supplied power is reduced to be enough to keep the state.

Title: Electrochromic element
Inventor: NAKAMURA MASATOSHI
IPC: G02F1/157
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent a photochromic phenomenon using no ultraviolet ray absorbent (or adding only tiny amount of it). SOLUTION: An electrochromic layer 10 comprising an electrochromic substance film 22 and an electrolytic liquid 28 is arranged between transparent electrode films 20, 24 of two glass substrates 12, 14. No ultraviolet ray absorbent is added to the electrolytic liquid 28. A photocatalyst layer 16 and a porous inorganic hydrophilic layer 18 are film formed on a surface side of the front glass substrate 12 to make a surface of an element hydrophilic. The photocatalyst layer 16 is excited by ultraviolet ray irradiation and decomposes stains adhered on a surface of the porous inorganic hydrophilic layer 18 to maintain hydrophilicity. Since the photocatalyst layer 16 absorbs the ultraviolet rays, the electrochromic substance film 22 is prevented from generating a photochromic phenomenon.
