Title: Production of fine powdery silica gel
Inventor: NOMURA MASARU
IPC: C01B33/16
Filed: 1994-11-11
Abstract: PURPOSE: To reduce load in a post-treating process and to obtain fine powdery silica gel having satisfactory performance by perfectly freezing a soln. prepd. by acid-treating calcium silicate hydrate and removing undissolved matter and then carrying out thawing and drying. CONSTITUTION: A soln. prepd. by acid-treating calcium silicate hydrate and removing undissolved matter is perfectly frozen, thawed and dried to obtain the objective fine powdery silica gel contg. <=80% particles of <=500μm particle diameter and having such a high hygroscopic rate as 45-55% in an atmosphere at 90% relative humidity. Even if calcium salt formed simultaneously with the formation of silica gel remains as an impurity, problem is not especially caused because the impurity is pressed out by gelling during the polymn. of silica gel and it is removed by simple washing. When the resultant silica gel is used in a field in which the problem of rust and corrosion is caused, treatment with sulfuric acid is most desirably carried out so as to prevent deliquescence even in the case of the penetration of the impurity.

Title: Resin-sealed semiconductor device
Inventor: HARIGAYA MAKOTO
IPC: H01L23/31
Filed: 1988-11-01
Abstract: PURPOSE:To relieve stress due to differential thermal expansion coefficient between a silicon substrate and sealing resin through a surface protective board by preventing direct contact of the sealing resin with a portion or the entirety of surface protective film covering a semiconductor chip. CONSTITUTION:Circuit elements are formed on the silicon substrate 1 placed on a die-pad 12. Predetermined wiring such as first and second layer wirings are formed on the silicon substrate 1 through a layer insulation film 9, then a surface protective film 6 composed of silicon oxide film, for example, is formed on the surface of a semiconductor chip through CVD. A surface protective board 5 having same size as the semiconductor chip and opened only above a pad 11 is applied onto the surface protective film 6 such that it can be connected through a bonding wire 3 with a lead frame 2. The semiconductor chip is wire bonded to an external lead frame 2 through the opening of the surface protective board 5 then it is resin sealed. Since the surface protective board is not connected with the semiconductor chip, thermal stress of the sealing resin is entirely absorbed through the surface protective board 5 and not transmitted to the surface of the semiconductor chip thus suppressing occurrence of crack. In order to absorb thermal stress of the sealing resin efficiently, polymer resin insulator is employed.

Abstract: PURPOSE:To reduce the fatigue of a worker who works for a long time by providing at least five momentary switches included in each of two oval input devices for right and left hands that can transmit various types of instruction information by the wire or wireless system. CONSTITUTION:The oval information input devices 1 and 2 can be easily held by the right and left hands. Each of these devices 1 and 2 is provided with the momentary switches 3-7 which are operated by a thumb, a forefinger, a middle finger, a third finger, and a little finger respectively. Thus the devices 1 and 2 are held by the right and left hands respectively and the fingers are applied to each of the corresponding switches 3-7. Then an optional combination of fingers is selected among 1023 ways of combinations of 10 fingers in all for input of characters, symbols, instructions, etc. The number of combined information are shown in an equation I, where (m) means 10, i.e. the number of finger switches and (r) means the number of switches that are depressed simultaneously. In such a manner, the movements of fingers can be decreased for input operations since the input operations are limited to only the depressing actions of the fingers of both hands. Thus the fatigue can be reduced for a worker who works for a long time.

Filed: 1988-11-01
Abstract: PURPOSE:To make an apparatus compact and light in a simple constitution by providing the constitution wherein a phase shifter is inserted between any parts of a branching means, a mixer and a transmitting and receiving antenna. CONSTITUTION:This apparatus is composed of a non-modulating carrier oscillator 101, a halving device 102, a circulator 103, an antenna 104, a phase shifter 105, mixer 106 and a signal processor 107. The phase shifter 105 is inserted between the having device 102 and the mixer 106. In an interrogator 1, the modulated wave of a responder 2 which is received with the antenna 104 is inputted into the mixer 106 through the circulator 103. The output of the oscillator 101 which is distributed to the phase shifter 105 through the halving device 102 is inputted into the mixer 106. The shifter 105 is controlled with the processor 107. The phase of the locally oscillated wave is continuously changed in a specified period, e.g. from 0 deg. to 108 deg. at e.g. from 1ms to 2ms. The output is received in the mixer 106. The processor 107 demodulates the output of the mixer 106 by the odd number of times at the period of the phase change. Thus the received data are obtained. Therefore, a point where the output of the demodulated signal becomes 0 and disappears is shifted, and the intrinsic data of the responder 2 can be demodulated.
