Title: Electrostatic charge image developer
Inventor: KASUYA RIYUUHEI
IPC: G03G9/097
Filed: 1983-10-18
Abstract: PURPOSE:To improve fluidity and nonagglomerativity and to obtain an always stable superior image high in resolution by using a mixture of an insulating magnetic toner powder specified in particle diameter and heat treated in a suspension state, fine particles of metal oxide, and a metal salt of fatty acid specified in carbon number. CONSTITUTION:A developer is composed of a mixture of an insulating magnetic toner powder heat treated in a suspension state and contg. 10-80wt% particles of 1-10mum particle diameter, fine particles of metal oxide, and a fatty acid metal salt having >=16 C number. Since the toner particles are globed by heat treatment, and the fine particles of metal oxide are mixed, fluidity and nonagglomerativity are overall raised, and since the surface of each toner particle is smoothed and electrostatic chargeability is improved by the heat treatment, superior developing performance and transferability can be obtained. The addition of the fatty acid metal salt prevents formation of small grooves on the surface of an electrostatic charge image bearing body and the contact end of cleaning blade, enhances durability, and also prevents fine toner particles, etc., from remaining on the surface of said body. As a result, a sharp image high in resolution can be obtained.

Title: Surge detecting device for engine
Inventor: HARADA TAKAYUKI
IPC: F02D45/00
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent a mistake in determination of a surge, by avoiding an effect of rotation speed variation due to a lockup clutch of a torque converter of a transmission. SOLUTION: A surge index value FILDMP is set on the basis of engine rotation speed variation at S101, and a surge reference determination value SFILD0 corresponding to a present operating region is set at S102. And, a surge determination value SFILD is computed at S104 by multiplying the surge reference determination value SFILD0 by a correction value KSFILD set on the basis of a difference between input and output side rotation speeds of a lockup clutch. The surge index value FILDMP is compared with the surge determination value SFILD at S105. Accordingly, a surge is detected in the case of FILDMP>SFILD, while no surge is detected in the case of FILDMP<=SFILD. Thus, an effect of variation in slip amount of the lockup clutch is avoided so that a surge is properly detected.

Title: Absorbing and removing apparatus for water deposit on surface
Inventor: KANDA EIZABURO
IPC: F26B5/16
Filed: 1991-07-09
Abstract: PURPOSE:To make the production and maintenance easy by providing a spiral ridge around the surface of a squeezing roller. CONSTITUTION:A squeezing roller 3 is 35mm in diameter and 600 mm in width, for example, and a Teflon pipe 4 with a diameter of 10 mm is spirally wound around the surface of the squeezing roller 3. The squeezing roller 3 and a water- absorbing roller 2 are mounted on a pair of frames 5 and 6 so that the squeezing roller 3 comes in contact with the plane surface of the water-absorbing roller 2. The sponge layer of the water-absorbing roller 2 is locally squeezed by the Teflon pipe 4 with a diameter of 10mm spirally wound around the surface of the squeezing roller 3. That is, as the squeezing roller 3 has a very small contact area with the water-absorbing roller 2 in comparison with a plane surface squeezing roller, a smaller compression force is required to squeeze the water-absorbing roller 2. Therefore, the self-weight of the water-absorbing roller 3 alone satisfies the compression force required, so that a compression mechanism is unnecessary to provide, leading to a simplified construction and an easy maintenance of the apparatus.

IPC: G06F13/36
Filed: 1988-08-03
Abstract: PURPOSE:To minimize the waiting time for application of data buses and to improve the data transfer efficiency by dividing the data buses into plural groups in the bit direction and adding a busy line and a request line to each group of data buses. CONSTITUTION:The data buses 1a-1d are divided into plural groups in the bit direction. These groups of data buses contain the busy lines 2a-2d and request lines 5a-5d respectively. The bus user circuits 3a-3d drive independently the buses 1a-1d for each group. Thus, the buses 1a-1d are driven only in the groups having the desired bit width based on the busy signals of the lines 2a-2d and the information on the lines 5a-5d. At the same time, only the busy signals of the busy lines of the driven groups are driven to show the busy modes of the relevant groups. As a result, the waiting time is minimized for application of data buses.
