Title: Catalyst for purification of exhaust gas
Inventor: ITOU HISANORI
IPC: B01J23/46
Filed: 1988-10-11
Abstract: PURPOSE:To effectively utilize noble metals and to obtain durable high activity catalyst for purification of exhaust gas by incorporating Pd-Nd multiple oxide and Rh-La multiple oxide into an alumina coated layer on a fireproof carrier. CONSTITUTION:A proper reagent such as ammonium carbonate is added to a soln. contg. a easily soluble Pd compd. such as palladium nitrate and a easily soluble Nd compd. such as neodymium nitrate to form a Pd-Nd coprecipitate. An Rh-La coprecipitate is similarly formed. The coprecipitates are added to an alumina slurry and a fireproof carrier is coated with the slurry, dried and calcined to obtain a catalyst. Since the mixed state of Pd and Nd and that of Rh and La are very satisfactory and the growth of Pd and Rh grains is inhibited, the noble metals are effectively utilized without waste and the activity and durability of the catalyst are enhanced.

Title: Screw for reaction injection molding
Inventor: SHIROTA AKIRA
IPC: B29C45/60
Filed: 1988-10-11
Abstract: PURPOSE:To sufficiently knead both liquid substance and a liquid curing agent with a simple constitution and also to enhance efficiency of reaction injection molding by providing a barrier part for increasing flow path resistance to the starting part of the metering zone of an injection screw and providing a mixing part for performing agitation of material at a time for rotating the screw to the terminal part of a feeding zone. CONSTITUTION:The substance such as polyol liquid and isocyanate liquid is supplied to an injection cylinder 2 with an injection screw 1 built-therein from a feed port 4. When kneading and weighing are performed by rotating the injection screw 1 with an ordinary means while controlling back pressure, substance is not easily passed but stagnated in the screw-grooves formed between the flights 5 even when substance has low viscosity because the aperture area is small and flow path resistance is large in a mixing part 6 and the barrier part 7. While the substance supplied to the feeding zone A is sent forward by transferring force due to feed pressure and the flights 5, it is stretched and kneaded and furthermore agitated and distributed in the mixing part 6 and also sufficiently diffused and sent to a compression zone B.

Title: Dehydration of alcohols
Inventor: SAITOU HIROTAKA
IPC: C07C29/82
Filed: 1988-10-14
Abstract: PURPOSE:To carry out efficient dehydration of alcohols with little energy consumption using a simple apparatus by performing azeotropic distillation of a monohydric alcohol using methyl tert-butyl ether as a novel azeotropic agent. CONSTITUTION:A 2-4C monohydric alcohol is dehydrated by azeotropic distillation by using non-toxic methyl tert-butyl ether(MTBE) having physical and chemical stability as an azeotropic agent. Since MTBE is stable, the distillation can be carried out without using particular apparatus while saving the operation labor and suppressing the variable cost. The energy consumption can be decreased owing to low latent heat of evaporation of MTBE. The operation pressure can be freely varied to normal pressure or positive pressure according to the condition of the supplied steam and, accordingly, the optimization of the process for energy saving can be easily carried out.

Inventor: IZUMI TAKAYUKI
IPC: H01L31/04
Filed: 1994-09-27
Abstract: PURPOSE: To provide a solar cell module improved with respect to the photoelectric conversion efficiency, weather resistance and durability. CONSTITUTION: The title solar cell module 100 is almost composed of a box-like back protective plate 1, second Al-made collector 10 having grooves 11 with parabolic cross-section and disposed in the plate 1, filament structures 20 disposed in the focal zones of these grooves, and protective member 30 disposed at the light incident side of the electrode 10.

Abstract: PURPOSE:To obtain a highly stable resonator having a large frequency variable width by setting up the pitch of electrode tips of a driving electrode, the pitch of electrode layers of a repeller and an interelectrode-tip pitch between the driving electrode and its opposed repeller to 1/2 the wavelength of an elastic surface wave. CONSTITUTION:The elastic surface wave resonator 11 is obtained by evaporating an aluminum film with thickness >=1% the wavelength lambda of the elastic surface wave on the surface of a piezo-electric body 2 segmented from a 36 deg. rotated Y plate consisting of LiTaO3 monocrystal in vacuum and removing its unnecessary part to form the driving electrode 3 and the repeller 4. The pitch P1 of the electrode tips 5a of the driving electrode 3, the pitch P2 of the electrode tips 4a of the repeller 4 and pitches P3a between the electrode tips 5a positioned on the right and left ends of the electrode 3 and the electrode tips 4a of the repellers 4 opposed to the tips 5a are set up to 1/2 the wavelength lambda of the elastic surface wave. Thereby, an ordinary spurious output generated in the vicinity of a main resonator disappears. Thus, a highly stable resonator with a wide frequency variable width can be obtained for a high frequency band voltage control oscillator(VCO).
