Title: Resin seal structure of element
Inventor: OTAKE KENICHI
IPC: H01L23/31
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent a seal resin from entering between a substrate and elements at resin sealing by electrically connecting the elements to the substrate with specified spacings, forming protrusions on the substrate and element peripheries to the protrusions with the resin. SOLUTION: Flip-chip mounting of elements 1 is made on a substrate 2, having protrusions (dams) 5 with a resin 6 covering the elements 1 to hermetically seal them 1 on the substrate 2. The dams 5 are similar convex frames on the substrate 2 and their height from the substrate is lower by about 10μm or less than the gap height after flip-chip mounting of the elements 1 on the substrate 2. The dams 5 block the resin from entering the gaps between the elements and substrate, to provide a high yield at resin sealing of the flip-chip- mounted elements.

Title: Removal of isobutene
Inventor: OKUMURA KINICHI
IPC: B01J31/00
Filed: 1983-12-27
Abstract: PURPOSE:To remove isobutene from an n-butene fraction containing isobutene as impurity, by treating the n-butene fraction with a strongly acidic cation exchange resin treated with a halide of Cu, Fe, Co, Ni, Sn or Al, thereby effecting the selective polymerization of isobutene. CONSTITUTION:An n-butene fraction containing a small amount of isobutene as impurity is treated with an acidic catalyst composed of a strongly acidic cation exchange resin treated with a halide (preferably fluoride or chloride) or Cu, Fe, Co, Ni, Sn or Al. Isobutene can be selectively polymerized and removed from the n-butene fraction by this process. The catalyst can be prepared, e.g. by impregnating a cation exchange resin in a solution of a metal halide, and drying the resin. The amount of the metal halide supported on the resin is preferably 0.2-5wt% based on the ion exchange resin. The reaction is carried out at 40- 65 deg.C, 5-30kg/cm<2>G and a liquid-space velocity of 5-25hr<-1>.

Title: Photoreceiver
Inventor: HIROHASHI KAZUTOSHI
IPC: H04B10/40
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To maintain a sufficient receiving level even in the case of emitting a transmitting light to a peripheral edge of a substantially hemispherical photodetector, by disposing a light receiving element at an opposite side of a light incident surface, and providing a transmission scattering film on a front surface of the incident surface. SOLUTION: A photoreceiver 13 comprises a substantially hemispherical photodetector 15 having a light incident surface 15A on a surface formed in a spherical shape. A plurality of light receiving elements 6 are assembled at an opposite side surface of the surface 15A, i.e., a center of an upper end flat surface, and disposed in close contact with the opposite side surface. And, a transmission scattering film 16 is provided near at an infinitesimal interval L2 ahead of a hemispherical done to cover the overall incident surface 15A of the hemispherical or dome-like photodetector 15. The film 16 has a function of partly reflecting the incident light and scattering the transmitted light. Accordingly, since the beam-like transmitting light is effectively inputted into the photodetector even if the light is emitted to an edge, a sufficient light receiving level can be obtained.

Title: Baffle for stirring tank
Inventor: IWATA MASAMI
IPC: B01F7/16
Filed: 1993-10-06
Abstract: PURPOSE:To form good vertically circulating flow and to improve stirring efficiency by constituting the baffle body of a stirring tank in such a manner that the angle of inclination with the axial direction of the stirring tank is changeable. CONSTITUTION:The angle of inclination of the baffle body 8 with the axial direction of the stirring tank is arbitrarily changeable if plural washers 10 formed at one end face 10a to various angles of inclination are prepd. Stirring vanes are first rotated by a revolving shaft and stirring is started when a driving means is started. The baffle body 8 inclines with the axial direction of the stirring tank 1 and, therefore, the internal soln. imparted with the flow of a circumferential direction by the respective stirring vanes is made to flow diagonally upward smoothly along the slope of the baffle body and the generation of the flow toward the lower side is suppressed and, therefore, the flow arrives at the liquid surface; thereafter, the soln. descends from the central part of the stirring tank 1. Namely, the good vertically circulating flow is eventually formed in the internal soln. and the internal soln. is uniformly and efficiently stirred in the entire area in the stirring tank.

Title: Open air purification material
Inventor: IBUSUKI AKITSUGU
IPC: B01D53/81
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To avoid to decrease removing properties of pollution substance caused by water and to improve removing properties per unit area in an open air purification material using titanium dioxide. SOLUTION: Titanium dioxide is activated by forming an outer layer contg. titanium dioxide on the surface of a base material 1 provided with water- repellency and with a number of unevennesses 11 and emitting ultraviolet rays on the outer layer 2 to activate the titanium dioxide. As water-repellency is provided on the surface of the base material and even when water is sticked on the surface, it is rapidly eliminated, decrease in removing properties of pollution substance caused by water is suppressed. In addition, as the outer layer 2 contg. titanium dioxide is formed on the uneven 11 surface of the base material 1, contact area between pollution substances and titanium dioxide becomes relatively large and removing properties per unit area becomes high.

Filed: 1990-09-20
Abstract: PURPOSE:To prevent the wasteful power consumption of a battery for backup by obviating operation as a backup power supply of an element or a circuit of the battery for backup by a switch circuit before another power supply is applied to the element or the circuit. CONSTITUTION:When supply voltage VCPU1 or VCPU2 is made to rise from a stabilized power circuit 22 or a DC-DC converter 25, pulses RS are acquired at the node of a resistor 27 and a capacitor 28, thus correctly resetting an IC 20. When the IC 20 is reset, one output signal SW of the IC 20 is changed from a low level to a high level. Since the base of a transistor 32 is supplied with the signal SW through an inverter 34, the transistor 32 is turned ON, and a battery 31 for backup is brought to the state in which the battery 31 starts operation as the backup power supply of the IC 20.
