Title: Secondary air control device for internal combustion engine
Inventor: HARADA KENICHI
IPC: F01N3/22
Filed: 1992-07-20
Abstract: PURPOSE:To promote catalytic warming by preventing increasing emission of HC, CO, etc., in the case of fuel increase operation when an engine is cold. CONSTITUTION:The first O2 sensor 6, first catalyst 3, secondary air introducing pipe 8, second O2 sensor 7 and the second catalyst 4 are successively arranged by this order from the upstream in an exhaust pipe 2 of an engine 1, and a supply amount of secondary air is controlled so that an output of the second O2 sensor 7 is obtained in a lean side when an engine is in fuel increase operation at cold time. Since a sufficient amount of oxygen is directly supplied to the second catalyst, shortening catalytic warming by purifying components of HC, CO and by promoting reaction is attained.

Inventor: SATO MASAHIRO
IPC: C07C323/62
Filed: 1989-07-25
Abstract: NEW MATERIAL:The optically active compound expressed by formula 1 (R and R' are 3-20C alkyl which may contain asymmetric carbon atom; X is single bond (direct bond) O, S, COO or OCOO; A1 and A2 are (F-substituted) 1,4- phenylene, 4,4'-biphenylene or 2,6-naphthylene].

Title: Display control system for crt
Inventor: SAKUMA MITSUTERU
IPC: G09G1/00
Filed: 1990-07-20
Abstract: PURPOSE:To display correct data of all times even if data in a register is rewritten owing to malfunction due to a discharge noise, etc., by writing the display data of one display image plane repeatedly in the register. CONSTITUTION:When the display image plane is rewritten, the display data is written in a memory 2 and the shift register 5 in synchronism with a rewriting signal to perform ON/OFF control over the CRT. Then the display data stored in the memory 2 is read out repeatedly during the display period of those data and written in the register 5. Therefore, even if wrong data is written in the register 5 owing to the discharge noise, etc., display data which ought to be displayed originally is written in the register 5 at the timing of a next loading signal, so the time for which the wrong display data is displayed is shorter than the time in which a human can recognize the data and the wrong display can substantially be ignored.

IPC: A61K8/86
Filed: 1985-08-31
Abstract: PURPOSE:To provide a black liquid cosmetic containing a titanium oxynitride having a diameter smaller than a specific level and a specific liquid humectant such as propylene glycol as essential components, having excellent line-drawing performance, applicability and safety and suitable as a pen-type cosmetic tool. CONSTITUTION:A titanium oxynitride containing 4-35wt% oxygen and 2-20wt% nitrogen and having particle diameter of <=1mum is used as a colorant of the objective black liquid cosmetic having a viscosity of 1.5-200cps. The cosmetic contains the above colorant and one or more compounds selected from propylene glycol, glycerol, polyethylene glycol and 1,3-butylene glycol as essential components. The amount of the glycol, etc., is 2-30wt% based on the colorant. Since the colorant is free from harmful substance, the obtained cosmetic is safe. The dispersion stability of the cosmetic is high because the colorant is non-magnetic. Furthermore, since the cosmetic has low viscosity and excellent applicability, it can be applied smoothly from the applicator without causing clogging when used as a pen-type cosmetic tool such as eyeliner.

Title: Impeller for bucket elevator of continuous unloader
Inventor: TANAKA YUJIRO
IPC: B65G65/20
Filed: 1984-09-17
Abstract: PURPOSE:To improve excavation performance, by a method wherein an engaging part between a sprocket and a chain is protected by a disc, the front in the direction of rotation of an impeller is open, plural sets of excavating blades are provided, and a chute is located to an inner end. CONSTITUTION:When a bulky material is unloaded through front excavation of a bucket elevator 1, the bulky material, falling in from sides, is prevented from cutting through an engaging part between a chain 2 and a sprocket 6 by means of a disc 7a. The sprocket 6 is reliably protected, and the bulky material is scooped in blades through rotation of an impeller 7 rotated integrally with the sprocket 6. The bulky material is guided to the bucket side through between the ribs of the sprocket 6 from holes formed in the disc 7a by means of a chute 8. This reduces resistance produced due to contact with the bulky material, and enables improvement of excavation performance.

Patent JP-H0359179-A (JP)
Title: Treatment of fiber structure
Inventor: HIRASA OKIHIKO
IPC: D06M101/16
Filed: 1989-07-26
Abstract: PURPOSE:To promote the reaction of a polymer and a compound using minimum amount of water necessary for the processing treatment by impregnating a fiber with a compound reactive with the fiber constituting polymer, laminating with a hydrated polymer gel sheet capable of reversibly sucking and releasing water by temperature change and heating the laminate at a temperature above the phase-transition temperature of said gel. CONSTITUTION:For example, in the thinning processing of a polyester fiber with sodium hydroxide or cotton fiber with cellulase, the fiber is impregnated with the compound reactive with the fiber constituting polymer and subjected e.g. to intermediate drying. The treated fiber is laminated with a hydrated polymer gel sheet capable of reversibly sucking and releasing water by temperature change (e.g. crosslinked gel of polyvinyl methyl ether) and the laminate is sealed, heated at a temperature above the phasetransition temperature of the polymer gel and maintained at the temperature. Water is released from the gel by this treatment to promote the reaction of the polymer and the compound in moistened state. The use of the gel is effective in preventing the waste of large amount of water in contrast to conventional process and enables the supply of necessary minimum amount of water in high efficiency to perform an energy-saving processing of the fiber.

Abstract: PROBLEM TO BE SOLVED: To completely push down entire instant noodles into hot water by providing, on a top plate of a lid, a recess for pushing down the noodles protruding downward to a depth equal to or a slightly lower than a liquid level of a predetermined amount of hot water poured into a container body. SOLUTION: A covering material is peeled off to open a lid 2, a bag containing materials, a bag containing seasoning liquid, a bag containing spice or the like are taken out from an empty space 23 in a recess, and respective contents are put into a container body 1. Then after hot water W is poured by a predetermined amount (to the vicinity or higher of a height of a water level mark 13), the lid 2 is put over.
