Abstract: PURPOSE: To avoid such a state that timer mechanism for expediting injection timing when the engine speed is high is not correctly operated due to the internal pressure pulsation of a gallery chamber caused by the vertical movement of a plunger in a distributor-injection type fuel injection pump that distributively injects fuel to a plurality of combustion chambers. CONSTITUTION: An accumulator 8 is additionally provided to dissolve the internal pressure pulsation of a gallery chamber 1a, and a timer piston 5 is provided with a small diameter communicating hole 5b and a large diameter communicating hole 5c bored to communicate a timer chamber 5a with the gallery chamber 1a. It is so constituted that only the small diameter communicating hole 5b communicates with the gallery chamber 1a when the internal pressure of the gallery chamber 1a is low and that the large diameter communicating hole 5c also communicates when the timer piston 5 ascends to a certain extent.

Title: Vaccine and its manufacture
Inventor: DENISU ERU KASUPAA
IPC: C12P19/00
Filed: 1979-08-16
Abstract: Culturing Streptococcus agalactiae in a nutrient broth containing at least 10 g l of glucose while maintaining the pH at 6-8 by the addition of alkaline material produces polysaccharide antigen including a fraction having a molecular size from 8-11 x 10<sup>5</sup>d. By employing a broth free from constituents having a molecular size above 10<sup>5</sup>, the antigens can be separated from the broth in high yield after harvesting the organisms. Vaccination of humans with Streptococcus agalactiae polysaccharide antigens having molecular sizes above 5 x 10' produces in selected individuals specific antibody levels above 200 µg ml of antisera; globulins fractionated from such antisera contain most of the antibody and can be used for passive immunization.

IPC: G06T1/00
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To provide an image input device capable of preventing the degradation of work efficiency in, at single-sheet feeding mode. SOLUTION: When the detection of a bias is made effective at selecting of the single-sheet feeding mode (manual insert mode), an effective bias detection flag is turned on (step S25), and when the bias detection is made ineffective, the effective bias detection flag is turned off (step S26).

Title: Computer system provided with printer monitoring function, computer system, printer, method therefor and computer readable recording medium
Inventor: MOMOSE HIROAKI
IPC: G06F3/12
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To improve operability for a user by reducing unneeded abnormality notification. SOLUTION: A 1st computer executes printing processing of a job A, and a 2nd computer executes printing processing of a job B. A printer starts to operate at the start point of the job A, that is, at timing t1 when it starts to output print data and finishes printing processing Pa after prescribed time ta passes. The 1st computer starts to execute monitor processing Ma at the timing t1 being the start point of the job A and after that, finishes executing the processing Ma at the end point of the processing Pa, i.e., at timing t2 when it receives a ready signal. Thus, since a monitoring period can be limited selectively, an unnecessary abnormality notification can be reduced.

Title: Drawing method of steel pipe
Inventor: ICHIKAWA MITSUAKI
IPC: B21C9/00
Filed: 1984-05-22
Abstract: PURPOSE:To prevent the seizure occurring in the deterioration arising from the cyclic use of a lubricating oil by coating the high-viscosity lubricating oil having substantially no fluidity to the required section on the pointing end side of the inside surface of a blank pipe prior to drawing of the blank pipe then drawing the pipe by using a plug while supplying continuously the lubricating oil to the inside and outside surfaces of the blank pipe. CONSTITUTION:The high-viscosity lubricating oil 8 is coated to the pointing part 5 on the inside surface of the blank pipe 1 as shown in the figure (p) prior to drawing. The blank pipe 1 is then drawn by a die 3 as shown in the figure (q). Since the oil 8 is of a high viscosity, the outflow of the oil coated on the upper side of the pipe 1 to the lower side and the consequent lack of the oil in the upper side part are obviated and the pipe is drawn satisfactorily while the high resistance to seizure is maintained. The oil is supplied continuously to the inside surface of the pipe, as shown by an arrow (b), through a mandrel 4 from an oil tank as shown in the figure (r) in succession to the end of drawing the pointing part 5 of the pipe 1 and the pipe is drawn while the inside surface thereof is lubricated. The crop 9 at the pipe end is discarded as shown in the figure (s) upon ending of the drawing. The oil 8 is fully removed together with the crop 9 to the outside of the system and therefore the inside surface of the product pipe is surely prevented from staining by the residual oil.
