Title: Semiconductor device using low-stress resin bonding agent composite
Inventor: MURAYAMA MASAKAZU
IPC: C08G59/20
Filed: 1993-05-27
Abstract: PURPOSE:To obtain a semiconductor device having a high thermal shock resistance by mounting a semiconductor chip and lead frame on the device by using a low-stress resin bonding agent composite containing an epoxy resin. CONSTITUTION:The flexibilizer contained in the low-stress resin bonding agent used to the semiconductor device has two hydroxyphenyl groups in one molecule and is a reaction product between modified silicone oil having a 500 to 4,000 number-average molecular weight and an epoxy resin. The curing agent contained in the bonding agent used for the semiconductor device is composed of a microencapsulated imidazole derivative and/or solid imidazole derivative having a melting point of >=70 deg.C. Therefore, no coming-out gas nor voids are generated at the time of curing a bonded section and the obtained semiconductor device is improved in thermal shock resistance. In addition, the die bonding process can be incorporated in a line at the time of manufacturing semiconductor elements.

Title: Digital multi-meter, electronic measuring device, and automatic range function control method
Inventor: SZABO PAUL I
IPC: G01D3/024
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To select the optimum measuring range considering the dynamic range of each measuring range of DMM. SOLUTION: RMS processor 214 and a peak detector 216 determine the RMS and peak of a signal to be measured. Control μP 220 compares the determined RMS and the peak with a prescribed critical value/threshold, and selects a measuring range by controlling SW 201, 202, 203 corresponding to the compared result. In this case, if the RMS is below a prescribed effective limit and a peak signal does not exceed a prescribed peak relative to the next lower measuring range, the next lower measuring range is selected.

Title: Room air conditioner
Inventor: SHIGENO SATOMI
IPC: F24F1/00
Filed: 1985-06-12
Abstract: PURPOSE:To contrive to prevent condensate from adhering onto a cold air discharge port by a structure wherein a flow uniforming frame, which has an acute dihedral angle made by the inside surface of the discharge port and a surface disposed to the interior of a room and is made of foam insulating material, is provided. CONSTITUTION:The second indoor air flow (e) is developed at the periphery of a cold air discharge port 2b due to the action of cold air (d) without producing any eddy currents, because the cold air (d) and the air flow (e) flowing along the periphery of the cold air joins each other smoothly. Concretely, no air flow (e) enters into the inside surface 7a of the cold air discharged port 2b from its periphery, resulting in producing no adhesion of condensate onto the inside surface 7a of the cold air discharge port 2b. In addition, because a flow uniforming frame 7 is made of foam insulating material, the heat insulating performance of which is more excellent than that of a decorative cover 2, the adhesion of condensate onto an exposed surface 7b due to heat conduction can be prevented from developing, even under the condition that the dihedral angle made by the top surface 7a and the exposed surface 7b of the flow uniforming frame 7 is acute or thin.

Title: Flat cable
Inventor: TANAKA KEIICHI
IPC: H01B7/08
Filed: 1994-06-08
Abstract: PURPOSE:To prevent discontinuity caused by repeated insertion and removing by forming a 0.5-1.5mm non-adhesive part in a root. CONSTITUTION:A 0.5-1.5mm non-adhesive part is formed in a root. Even if inserting and removing operation is repeated in such a way that the vicinity of the root of a reinforced tape is bent 90 deg., then this part is inserted into a connector, and a flat cable is pulled straight, discontinuity of the conductor is hardly seen and the number of inserting and removing can be increased.

Title: Reflecting mirror
Inventor: FUJISHITA YOSHIYA
IPC: E01F9/658
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent dew condensation and frosting over a long period by holding a mirror surface plate with a back plate, inserting a radioactive material covered with a shield between the mirror plate and the back plate, and warming the mirror surface plate with the decay heat generated when the radioactive material decays. SOLUTION: The front surface of a mirror surface plate 1 made of a synthetic resin or a metal is formed into a mirror surface 11, and the front surface of the mirror surface plate 1 is polished to form a mirror surface layer with an acrylic resin. A back plate 2 for holding the mirror surface plate 1 is fitted to the back face of the mirror surface plate 1, and the back face side of the back plate 2 is fixed to a support metal 3 fitted to a stanchion 4 erected on a road surface. A radioactive material 5 covered with a shield 51 of lead to prevent the leakage of noxious radioactive rays to the outside is inserted between the mirror surface plate 1 and the back plate 2. The decay heat generated when the radioactive material 5 decays warms the mirror surface plate 1 through the shield 51.  Uranium generates decay heat until it is finally stabilized, and dew condensation and frosting can be semipermanently prevented without requiring maintenance.

Title: Descrambler
Inventor: OKAMOTO EIJI
IPC: H04L9/26
Filed: 1982-07-20
Abstract: PURPOSE:To decrease erroneous transmission and to prevent the interpretation by the 3rd party, by outputting data descrambled in response to a scrambled and an output of a function generator. CONSTITUTION:A shift register 103 stores sequentially the scrambled data inputted from an input terminal 107. A pattern generator 102 outputs a digital pattern in a predetermined order. The function generator 104 outputs a digital pattern (random number) in response to an output of the register 103 and the generator 102 depending on a key pattern from an input terminal 106. An exclusive OR element 105 outputs an exclusive OR between an output of the generator 104 and data from the terminal 107. Thus, the erroneous transmission is decreased and since the random number depends on the scrambled data, the scrambled result is hardly interpreted by the 3rd party.

Abstract: PROBLEM TO BE SOLVED: To provide a security device in which no dead angle exists in the detection of an intruder, a detection part for the purpose is not revealed and which can work at inexpensive cost. SOLUTION: A surface heating element for a floor heater is used as a structural element for a two-dimensional detection means. A metallic sheet 1(3) is spread over a back heat insulation material 1(2) of the surface heating element 1(1) spread over the back surface of a floor of a closed floor heating space in a building and a high frequency signal is added to the surface heating element 1(1) and the metallic sheet 1(3). The high frequency signal indicating vacant state in which the floor heating space is not used, is stored in advance and the high frequency signal is added to the surface heating element 1(1) and the metallic sheet 1(3) in the vacant state. When the high frequency signal indicates a state which is different from the vacant state, this is responded and an alarm is generated. According to this structure, whenever an intruder steps on the floor, intrusion is detected.

IPC: F15B11/15
Filed: 1978-10-17
Abstract: PURPOSE: To eliminate damage or danger of a double cylinder type hydraulic piston, by hydraulically controlling a pilot valve through sub-cylinders of the double cylinders.  
     CONSTITUTION: Double type cylinders 21, 21a have their sub-cylinders 24, 24a which are connected with a pilot chamber of a pilot valve 26 through passages 36, 37 and the pilot valve 26 is controlled by fluid pressure from both sub-cylinders 24, 24a. Since the pilot chamber is kept under constant pressure without being influenced by the hydraulic pressure thus fed, the pilot valve 26 can be controlled only by the differential pressure required for transferring the spool, which contributes to eliminate damage or danger of the device.
