Patent JP-S6356023-A (JP)
Title: Satellite broadcast reception equipment
Inventor: KANDA MINORU
IPC: H04B1/26
Filed: 1986-08-26
Abstract: PURPOSE:To eliminate disadvantage due to static electricity and to suppress the fluctuation of a bias voltage of an input section of a converter by providing a filter circuit comprising an inductive element and a capacitive element between a plane antenna and an amplifier circuit. CONSTITUTION:The filter circuit F consists of the inductive element L11 connecting a transmission line 13 and ground and the capacitive element C11 connected between the inductive element L11 and a post-stage of a connecting point of the transmission line 13 and provided between the plane antenna 11 and a low noise amplifier circuit 15. Since the inductive element L11 grounds the plane antenna 11 and ground in terms of DC, a low frequency noise such as static electricity or lightning surge invaded from the plane antenna is escaped to ground. A reception signal from the antenna 11 has a high frequency, then the signal is not led to ground through the inductive element L11 but sent to the converter 12. Moreover, the capacitive element C11 cuts off the plane antenna 11 and the low noise amplifier circuit 15 in terms of DC, then the fluctuation of the bias voltage is suppressed.

Title: Method and mold for producing laminated molded product
Inventor: SHIBATA YASUMASA
IPC: B29C45/14
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To obtain a laminated molded product excellent in both of appearance quality and strength even when a thick-walled part is partially formed. SOLUTION: When a laminated molded product having a thick-walled part larger than other part in a thick wall dimension partially formed thereto is produced, a mold 20 having a skin surface material preliminarily arranged therein is filled with a molten resin 2 and nitrogen gas is introduced into the gap between the molten resin 2 around a thick wall molding part 30 and a molding surface 23 from a pressure introducing part 31. Since the nitrogen gas presses the molten resin 2 toward a molding surface 25 until molding is completed and the molten resin 2 is continuously brought to the close contact with the molding surface 25, the molten resin 2 generates no sink in the surface on the side opposite to the thick-walled part formed to the thick-wall molding part 30 and, since the thick-walled part is solid, a strength problem is not generated at all.

Abstract: PROBLEM TO BE SOLVED: To improve the specific Young's modulus of glass and also to increase the productivity of a glass substrate by specifying composition ratios of SiO2, Al2O3, MgO and TiO2 being main components. SOLUTION: The composition range of main components are kept in 50.5-52.5% SiO2, 10-30% Al2O3, 10-30% MgO and 4-10.6% TiO2 by weight ratio. When SiO2 is less than 50.5%, melt property becomes worse, and when SiO2 is more than 52.5%, crystal is hardly precipitated. When Al2O3 is less than 10%, a precipitated crystal is small and strength is low, and when Al2O3 is more than 30%, melt temp. becomes high and the glass is liable to devitrify. When MgO is less than 10%, the chemical durability of a glass matrix phase is not improved, and when MgO is more than 30%, other crystalline phase is precipitated and desired strength is difficult to obtain.  When TiO2 is less than 4%, melt property becomes worse and also crystal growth is hardly caused, and when TiO2 is more than 10.6%, crystallization is rapidly accelerated, and the control of crystallization state becomes difficult, and fine and homogeneous crystalline structure is not obtained.

IPC: G03F7/20
Filed: 1988-08-11
Abstract: PURPOSE:To obtain a substantial surface light source by providing a fly-eye type integrator where positive or negative lenses are arranged in parallel by putting a relay lens between them and a prismatic internal reflection type integrator. CONSTITUTION:The image of a condensing point group formed by the fly-eye type integrator 10 is formed near the incident plane of the internal reflection type integrator 20, so that the lens can be prevented from being destroyed by heat at the time of condensing. The image S0 of a light source near the incident plane 20a of the square pole-like integrator 20 passes through an exit plane 20b. The luminous flux reflected on a side surface 20c is projected as if it is from a virtual condensing point S1 which is conjugated with the S0. Thus, the divergent luminous flux from the point S0 is reflected on the wall surface and projected as if the light beams are supplied from many light source images in substance. Then, the exit surface 20b is irradiated with the luminous flux from many condensing points distributed in a grid pattern and the substantial surface light source is formed on a surface S.

Title: Angular speed sensor
Inventor: HARA NAOKI
IPC: G01C19/56
Filed: 1984-09-25
Abstract: PURPOSE:To make it possible to detect an angle accurately, by offsetting the lead of an AC driving voltage caused by capacity coupling between a driving part and a detecting part by the action of a phase inverting circuit, thereby extremely reducing a voltage generated between output terminals. CONSTITUTION:An AC driving voltage is applied to a driving piezoelectric bimorph 1' through a phase inverting circuit 6 so that the phase of an AC driving voltage, which is applied to a driving piezoelectric bimorph 1, is different by 180 deg. from the phase of an AC driving voltage, which is applied to a driving piezoelectric bimorph 2'. The polarizing directions of the piezoelectric bimorphs 1 and 1' are the directions shown by dotted arrow lines in the figure so that they are vibrated in 180 deg. out of phase even if the AC driving voltage is applied. The phase of each AC driving voltage, which leaks through coupling capacitor C3 or C3', is shifted by 180 deg. because the phase inverting circuit 6 is provided. The voltages are synthesized and offset. Thus the offset voltage generated between output terminals (a) and (b) can be reduced to the extremely small value.
