Title: Mounting method for semiconductor device
Inventor: YAMAKAWA KOJI
IPC: H05K3/34
Filed: 1992-04-28
Abstract: PURPOSE:To reduce the strain generating in a resin material when thermal history is applied in case where any difference in thermal expansion ratio exists between a substrate and a package body by interposing a non-hardened resin material between the substrate and the package body. CONSTITUTION:A non-hardened thermosetting or photosetting resin material 21 is interposed between a semiconductor device 1 and a substrate 18. After a land 17 on the substrate 18 is connected electrically with the land 17 on the device 1 by soldering 20, the material 21 is filled between the both to be applied with thermosetting or photosetting treatment. The material 21 reduces the strain generating because of having been applied with thermal history, and prevents the joint part from breakage. Therefore, highly reliable mounting can be performed for the substrate even when a surface mounting type package with high density, high-speed correspondence, and high reliability is used.

Title: Input switching circuit
Inventor: JINNO KEIJIROU
IPC: H03K17/62
Filed: 1982-06-28
Abstract: PURPOSE:To reduce the cost of a titled circuit, by outputting selectively an input to an output terminal with a control voltage. CONSTITUTION:Control voltages Vc1, Vc2 are applied to transistors(TRs) 1, 2, through base resistors 15, 15'. When the control voltage Vc1 is ''high'' and the control voltage Vc2 is ''low'', the TR1 turns on and the TR2 turns off, then a TR7 is cut off, resulting in that only an input in1 inputted via a capacitor 13 is outputted. In inverting the control voltages Vc1, Vc2, a TR3 is cut off, and an input signal from in2 appears at an output terminal (out). Thus, the input switching circuit is constituted with less number of elements.

Filed: 1990-04-25
Abstract: PURPOSE:To make it possible to measure an etching depth in a substrate to be etched at a real time while irregularities in the etching depth and an etching form in the substrate are inhibited by a method wherein a transparent conductive layer is formed on the surface of a light-transmitting window and this transparent conductive layer is grounded along with a vacuum container. CONSTITUTION:A transparent conductive layer 7 is formed on the surface, which is located on the side of a vacuum container 1, of a light-transmitting window 5 and a terminal 8, which is attached to the lower surface of the upper wall of the container 1 and has an elasticity, is brought into contact to the layer 7 and is grounded along with the container 1. Accordingly, in case high-frequency power is applied to an electrode 2 on the other side from a high-frequency power supply 3, discharge can be caused favorably by the covered layer 7 even at a place on the window 5 consisting of an insulating material (quartz), consequently, the discharge can be evenly caused between the electrode 2 and the container 1. Thereby, while irregularities in an etching depth and an etching form in a substrate 17 to be etched are inhibited, the etching depth in the substrate 17 can be measured by a measuring mechanism 12 at a real time.

Filed: 1992-04-28
Abstract: PURPOSE:To process the film forming of plural materials simultaneously by providing a radial ion beam generating device, a vacuum chamber, plural spatter targets and holders, and the like. CONSTITUTION:Ion beam 21, emitted from the emitting holes 22 of a radial ion beam generating device 1, collide with spatter targets 23, 24 respectively, and there the metals of the targets 23, 24 become deposition particles p by a spattering action so as to attach to materials to be film formed 25, 26 to form films.

Abstract: PROBLEM TO BE SOLVED: To drain a part of water in a drainage channel into a roadbed, to prevent the inside of the drainage channel from becoming full even at heavy rain time, and to prevent an overflow of rainwater from a catchment port by arranging plural drain holes in side walls of a concrete drain block. SOLUTION: Rainwater fallen on a water impermeable roadbed 2 of a pavement flows in a drainage channel 14 from a catchment port 15 of a drain block 11 to be discharged into rivers and a sewage treatment plant. Plural drain holes 16 are arranged in both side walls 12, 12 of this drain block 11, and when a water level in the drainage channel 14 rises at heavy rain time, water is drained into the roadbed 1 side from the drain holes 16 to prevent the rainwater from overflowing from the catchment port 15 when the inside of the drainage channel 14 becomes full. The rainwater flowing out to the roadbed 1 side is preserved in a soil layer to be used as underground water or to be useful as moisture for a roadside tree to thereby prevent the rainwater from flowing backward from the drainage channel 14 at heavy rain time as well as to effectively use the rainwater as water resources.

Title: Portable telephone radio unit

IPC: H04B7/26
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To efficiently switch an antenna and to reduce the power consumption by turning off a power supply of a reception circuit to measure a reception level used for discrimination of antenna switching under a prescribed condition where no antenna switching is required. SOLUTION: The discrimination for antenna switching is not conducted under a prescribed condition where no antenna switching is required, and an antenna having been so far used is used as it is for the reception. For example, in the case that a reception level of an RX slot this time is higher than a prescribed threshold value and a signal error rate is smaller than a prescribed threshold value, the discrimination for antenna switching is not conducted for a succeeding LM slot and the antenna used for the RX slot this time is used for the succeeding RX slot. Then the power supply for a reception circuit and a demodulation circuit is turned off for the succeeding LM slot. The antenna switching is made efficient and the power consumption is reduced for a mobile phone radio unit adopting the antenna switching diversity.
