Filed: 1985-07-25
Abstract: PURPOSE:To control fuel injection amount to be suitable for combustion timing by providing a main plunger with an auxiliary plunger having a greater effective outer diameter than that of the main plunger on the periphery of and near the plunger chamber of the main plunger. CONSTITUTION:An auxiliary plunger 5 is arranged on the periphery of and near a plunger chamber 3 of a main plunger 4 so that the auxiliary plunger 5 starts compression stroke together with the main plunger 4 after the main plunger during its compression stroke has risen by DELTAl. Accordingly fuel necessary for explosive combustion period is injected during early stage of compression stroke and thereafter greater amount of fuel is injected during controlled combustion stage. As a result, operation of a Diesel engine can be made more similar to that of the Diesel cycle to improve the performance of the Diesel engine.

Abstract: PURPOSE: To rotationally drive the image carrier (photoreceptor) of a process cartridge at a uniform speed and to prevent the increase of the size of device and manufacturing cost, in an electrophotographic image forming device. CONSTITUTION: Driving force is transmitted to the photoreceptor 21, a developing roller 24, etc., in a process cartridge 20 from a driving motor 71 provided in an image forming device main body, through a reduction mechanism 74. Two gears 76 and 77 are engaged with a driving force transmission gear 75 existing in a driving force transmission path from the driving motor 71 to the photoreceptor 21 and the driving force is divided. The photoreceptor 21 is driven by the driving force transmitted to the photoreceptor driving gear 76, and the developing roller, an electrifying roller, a cleaning brush, etc., are driven by the driving force transmitted to the developing roller driving gear 77, and a load is not applied to the downstream side from the photoreceptor.  Thus, irregularities in rotation generated by the application of a heavy load can be prevented from propagating to the photoreceptor.

Filed: 1982-09-20
Abstract: PURPOSE:To provide a flocculant excellent in solubility and stability in a dissolved state, generating no maloder during dissolving and reduced in the fear of environmental pollution, by compounding chitosan in combination with a specific acid. CONSTITUTION:A flocculant contains chitosan, adipic acid and benzoic acid or a salt thereof and the componential ratio of chitosan : adipic acid : the other acid or the salt thereof is 1:0.2-5:0.01-2, pref., 1:0.3-1.0:0.02-0.2.

Filed: 1981-10-16
Abstract: PURPOSE:To decrease unevenness of sizing braking dimension and improve accuracy, by assuming an automatic sizing point as a point of time on a sizing  process curve and detecting the point of time on the basis of time. CONSTITUTION:Time t is taken on a horizontal axis, while a cut amount s or work dimension n is taken on a vertical axis. Measured values of up-to-date continued fixed numbers, for instance, n1t1, n2t2, n3t3 are obtained, and the method of least squares is used to perform arithmetic operation and obtain an approximate curve. When the next measured value n4t4 is input, calculation is again performed to obtain a more correct sizing process curve successively in a state of time series. A time tf to reach spark out start dimension nf as a point on said curve is calculated. The time tf is detected during actual work, when this time is detected, a control signal of the fixed sizing point nf is generated. In this way, conventional unevenness can be both logically and actually removed.

Title: Optical transmitter
Inventor: NAKATOI KAZUO
IPC: H04B10/077
Filed: 1985-07-25
Abstract: PURPOSE:To obtain an optical transmitter capable of checking easily the working state of an optical fiber by providing a check means generating an optical signal with a timewise constant level regardless of time change of a transmission signal input in response to the designation from a light emitting element. CONSTITUTION:A confirmation mode switch SW, a resistor R and a OR gate OR constitute a check means C in an optical transmitter S. When the switch SW is turned off, since one input to the OR gate OR is a transmission signal input, the output is the same waveform as the transmission signal input and the optical transmitter S acts like a conventional transmitter. When the switch SW is turned on, since the level of one input of the OR gate OR goes to 'H' by the voltage drop caused across the resistor R, the OR gate OR outputs an 'H' voltage independently of the other input. Thus, is turning on the switch SW, a timewise constant optical signal is obtained regardless of he change in the transmission signal input. Thus, the check of working state is facilitated.
