Title: Semiconductor device with heat sink
Inventor: MATSUBARA YUJI
IPC: H01L23/40
Filed: 1991-04-24
Abstract: PURPOSE:To mount in a high density by adhering a heat sink to both upper and side surfaces of a package. CONSTITUTION:A heat sink 3 is adhered to both upper and side surfaces of a ceramic case 8 with adhesive 4. Thus, a size of the case 8 for obtaining the same heat dissipating performance can be reduced as compared with that of a conventional structure. That is, when a heat transfer area of the upper surface of the case 8 is A3, a heat transfer area to be transferred from the side 2 of the sink 3 to a fin 1 of the sink 3 is A1, a thermal conductivity of the case 8 is lambda, and thermal conductivity of the sink 3 is lambdaH, A3/A1=lambdaH/lambda is obtained, and the heat transfer area can be reduced in the amount corresponding to larger conductivity of the sink 3. Thus, a size of a semiconductor device can be reduced, and a high density mounting is performed.

Title: Proximity switch
Inventor: KAI ISAO
IPC: H03K17/95
Filed: 1984-05-08
Abstract: PURPOSE:To detect the arrival of an object to be detected by providing a circuit comprising a resistor and the 2nd capacitor to an oscillating circuit additionally, allowing the said circuit to convert the change in the oscillating frequency due to the object to be detected into a loss and changing the oscillating gain depending on the amount of the said loss. CONSTITUTION:When the oscillating frequency gets higher, the impedance Z is decreased, a current Ix is increased and then the power consumed in a resistor Rx is increased, the load viewed from the oscillating circuit is increased and the oscillating gain is reduced. Thus, when a metal such as copper or aluminum with less high frequency loss approaches an oscillating coil L, the inductance L of the coil is decreased and the oscillating frequency is increased. Then the load current Ix is increased, the power consumption in the resistor Rx is increased and then oscillating gain is reduced. The arrival of a substance with less high frequency loss through a long approaching distance is detected by allowing a level discriminating switching circuit LSC to discriminate the reduction of the oscillating gain.

Title: Method for testing leakage
Inventor: SAKAKIBARA YOSHIO
IPC: G01L11/00
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To judge the quality of sealability by supplying pressure into an object to be inspected from a pressure source, exhausting the part of the pressure out of the object, stopping the supply of the pressure when the pressure arrives at the higher applied pressure than the testing pressure, continuing the exhaust ing of the pressure to reduce to the testing pressure, and observing the pressure change in the object. SOLUTION: One cycle of leakage test has pressure exhausting, balancing, detecting and exhausting steps. Before the pressure exhausting step, a pressurizing solenoid valve 24 is closed, and exhausting solenoid valve 25 is opened. In the pressure exhausting step, both the valves 24, 25 are opened, and pressurized air is supplied to an object 27 to be inspected by a regulator 22. When the pressure of the sensor 26 exceeds the testing pressure to arrive at the pressurized pressure, the vale 24 is closed, and the balancing step is started. The pressure is gradually lowered by the opening of the valve 25, and when sensor 26 arrives at the testing pressure, the valve 25 is closed, after an infinitesimal time is elapsed, it is transferred to the detecting step.  The sealability is judged from the reference value of the change of the pressure within a predetermined time of the object 27, and then exhausted from a branch pipe line 28.

Title: Control for supply of hot water for automatic bath device
Inventor: TANI MASAMI
IPC: F24H1/00
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To decrease the number of steps during the supply of hot water (particularly, the number of times of circulation decision) and reduce a required time for supplying hot water. SOLUTION: When an automatic hot water supply switch is turned on (step 51). the decision of circulation is executed (step 51a). As a result, when it is recognized that a water level is equal to or lower than the level of a bath adapter, hot water less by the quantity of hot water q1 (volume in the bath tub between a part just below the bath adapter and a reference water level) than the quantity of hot water Q1 up to the reference water level is supplied to the bath tub (step 52), so that the decision of circulation is carried out (step 53). When the decision of circulation is invalidated, the quantity of hot water more by the quantity equal to the quantity of hot water q1 than the quantity of hot water Q2 from the reference water level to a set water level is supplied to the bath tub 1 (step 54).

IPC: B01D35/027
Filed: 1988-04-18
Abstract: PURPOSE:To clean hot water while circulating the same and to remove the scale generated therein by sucking the hot water through a suction port which sandwiches a bivalent copper ion filter with foamed polyurethane, guiding the hot water into an active filter device, incorporating ozone thereto on the way and circulating the hot water to a bath tub. CONSTITUTION:The hot water in the bath tub 1 is sucked through the suction port sandwiching the bivalent copper ion filter with the foamed polyurethane and is guided into the active filter device 3, when a pump 2 is started. The ozone generated in an ozonizer 4 is incorporated into the hot water on the way to the discharge into the bath tub 1 through a discharge pipe 11 and this hot water is circulated through the discharge pipe 11 to the bath tub 1. The hot water is cleaned while said water is circulated by such constitution. Since the suction port is constituted as an interchangeable filter part, the port is easily removable when sludge accumulates therein. The fat and oil components in the sludge are oxidation-decomposed by the injection of the ozone and are thereby made easily collapsible. The scale generated during the circulation is thus removed.

Title: Fluidized bed burning device
Inventor: IDEI YASUMASA
IPC: F23C10/18
Filed: 1989-04-13
Abstract: PURPOSE:To reduce the loss of heat to enhance the thermal efficiency and prevent the fluidized medium from escaping by disposing a screen or a porous object to bridge across the free board section or the burnt gas outlet in the fluidized chamber, and disposing thereunder trapping plates to trap flying particles from the fluidized bed. CONSTITUTION:The waste gas which burnt in the fluidized bed F passes through an opening 60 in the shutter plate 54 to enter passages 56 between flying particles trapping plates 52. Said passages 56 are bent to deflect the gas flow so as to cause most of particles carried by the gas to collide the flying particles trapping plates 52 and drop down to the fluidized bed F. Part of the particles which are carried by gas to pass through the passages 56 stay on the metal screen 50, and the rest of the particles flows on to the waste gas outlet 30 along with the burnt gas. The burnt gas is released outside the furnace body 10 after exchanging heat with a heat transmission pipe 31 disposed in the outlet 30. During said process, the metal screen 50, flying particles trapping plates 52 and shutter plate 54 are heated by the heat of the waste gas and give a radiation heat to the fluidized bed F. Said radiation heat is absorbed by the fluidized medium in the fluidized bed to improve its capability.
