Title: Deodorizing device
Inventor: OZAKI KAZUHIDE
IPC: F24F1/00
Filed: 1988-12-27
Abstract: PURPOSE:To ensure an adequate rate of air discharge so as to obtain a high deodorizing efficiency and miniaturize the overall size of device by attaching a deodorant material for removing the odorant components in the air to the inner surface of air passages of a centrifugal air impeller which comprises superposed annular corrugated plates. CONSTITUTION:When a centrifugal air impeller 6 is rotated by means of a motor 4, the air in its center is sucked, the air outside the body casing 1, i.e., the air in the room, is sucked into the center of the centrifugal air impeller 6. Such air is caused to flow into and through a number of air passages 11 in the rotating centrifugal air impeller 6 toward the radially outer side. During the process, deodorant components contained in the air are caused to be absorbed and deodorized by a deodorizing material attached to the inner surface of the air passages 11. Thereafter, the deodorized air from the air passages 11 is supplied through the air outlet 3 to the outside, i.e., into the room. The suction and delivery of the room air is thus continuously performed, and so, all the air in the room can be ultimately deodorized.

Title: Cellulose ester composition and molded product
Inventor: ITO MASANORI
IPC: C08L101/16
Filed: 1994-12-05
Abstract: PURPOSE: To obtain a degradable cellulose ester composition high in both photodegradability and moldability, and useful for obtaining various molded products. CONSTITUTION: This composition comprises a cellulose ester such as cellulose acetate and anatase-type titanium dioxide >=30m<2> /g in specific surface area (1), 0.001-0.05μm in primary particle diameter (2), or 30m<2> /g in specific surface area and 0.001-0.05μm in primary particle diameter (3). For higher photodegradability and dispersibility, the titanium dioxide may be surface-treated with a phosphorus compound such as a phosphate, a polyhydric alcohol or an amino acid. Use of a low-substitution degree cellulose ester <=2.15 in average substitution degree can raise the biodegradability of this composition. Further, this composition may contain a plasticizer and/or aliphatic polyester and/or biodegradation promoter (e.g. an organic acid or its ester).

Title: Multilayer printed wiring board
Inventor: ASAI MOTOO
IPC: H01L23/12
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent the peeling of a conductor layer and an interlayer resin insulating layer and the crack of the interlayer resin insulating layer with a heat cycle condition and high temperature, high pressure and high humidity conditions by forming roughened layers on a part of the surface of the lattice- like conductor layer and connecting a via hole. SOLUTION: A lattice-like conductor layer operates as a power layer or a ground layer and roughened layers 5 are formed at least on a part of a conductor layer. The conductor layer is closely stuck to an interlayer resin insulating layer through the roughened layers 5. Thus, the conductor layer and the interlayer resin insulating layer are not peeled off even with a heat cycle condition and high temperature, high voltage and high humidity conditions. Since the lattice-like conductor layer operates as the power layer or the ground layer, a via hole 140 is connected but the lattice-like conductor layer is formed. Thus, superior adhesion property with the via hole 140 is given. The lattice-like conductor layer is formed of an electroless plating film and an electrolytic plating film.

Title: Frequency changing phase-synchronized oscillator
Inventor: TAKAYANAGI TADASHI
IPC: G01S7/28
Filed: 1989-12-20
Abstract: PURPOSE:To oscillate a variable frequency oscillator with a phase synchronized with that of the oscillation of a reference oscillator by comparing the phases of part of the output of the reference oscillator and part of the output of the variable frequency oscillator having modulation characteristics equivalent to those of the reference oscillator with each other, combining the output of the reference oscillator and a modulation signal and applying a resultant signal to the variable frequency oscillator. CONSTITUTION:A prescribed modulation signal is inputted from a modulation signal source 2 to exciters 3 and 7 to temporally change the oscillation frequencies of a reference oscillator 1 and of a variable frequency oscillator 4. Part of the oscillation output of the oscillator 1 and part of that of the oscillator 4 are inputted to a phase detector 5 wherein phases are compared with each other, an error signal corresponding to a phase difference is amplified by use of a loop amplifier 6 and combined with the modulation signal from the modulation signal source 2 in the exciter 7 to control the oscillator 4, which oscillates with a phase synchronized with that of the oscillation of the oscillator 1. Thus, since the output level of the amplifier 6 is not required to be high, the oscillator 4 can oscillate with the phase synchronized with that of the oscillation of the oscillator 1 even when an oscillation frequency is changed in a wide frequency width and at a large frequency changing speed.

Abstract: PURPOSE:To measure the minor displacement of a sample at an extremely low temperature with high resolution without requiring the frequent optical path adjusting work by a complex optical path adjusting system. CONSTITUTION:One end of a sample W is fitted to a tensile rod 9 transferring the tensile stress to the sample W at an extremely low temperature, and the other end is fixed to a sample support structure body 10. A light frequency shifter 22 emits a laser beam having two different frequencies in parallel with the application of the tensile stress to the sample W. The laser beam is uniformly divided into the reference light and the detection light having two frequency components by an unpolarized beam splitter 24. The detection light is divided by the polarization plane of a polarized beam splitter 30, and the displacement of the sample W is substituted into the optical path difference of the laser beam having each frequency by two corner cube prisms 31, 33 fixed on the moving side and the fixed side of the sample W. The reference light and the substituted detection light are converted into beam signals respectively by polarizers 26, 28, and the optical path difference, i.e., the displacement of the sample W, is measured from the phase difference between the beam signals.
