Title: Electrostatic charge image developing toner
Inventor: SASAGAWA MASUMI
IPC: G03G9/08
Filed: 1983-11-30
Abstract: PURPOSE:To form a high-quality image by enclosing a magnetic material and carbon black, forming particles having a Wadell's practical sphericity in a substantially spherical range, and rendering the carbon black hydrophobic. CONSTITUTION:The toner to be used is substantially spherical and uniform in particle diameter, and has a Wadell's practical sphericity of 0.95-1.00, and a number average particle diameter of 5-25mum. When carbon black is made hydrophobic by treating the surface with a Ti coupling agent or silane coupling agent or the like, polymerization is executed stably, and since the carbon black is located in the inside of the polymer, good insulating property is attained. This toner is superior in fluidity, and since the particles are of approximately true spheres, and fine and coarse particles are small in amt., the toner is uniformly triboelectrified, and an image free from fog and scattered small spots can be obtained. Since specific resistivity under compressed and pressurized conditions is as high as >=10<13>OMEGAcm, electrifiability is stable and stable development characteristics can be obtained irrespective of temp. and humidity.

Title: Receiver for polarization diversity reception by square-law recombination of baseband signal
Inventor: PIITAA UERUNAA HOOIIMANSU
IPC: H03D7/12
Filed: 1991-09-04
Abstract: PURPOSE: To provide a receiver independently of a direction of a polarized wave, in which only up to three control amplifiers are required and the gain of the amplifiers is identical. CONSTITUTION: A polarized signal is separated into two components, which are orthogonal to each other, before the polarized signal is converted into an intermediate frequency signal. In order to combine the two intermediate frequency signals with a baseband signal independently of a direction of the polarized wave, a demodulator with a quadratic relation is used between an input signal and an output signal. In order to obtain this quadratic relation, the intermediate frequency signal is separated into two signals, whose amplitude is equal to each other and whose phases are opposite to each other. A sign of odd number terms in the sum of currents flowing into diodes 27, 28 is opposite to the sign of even number terms in the sum of currents flowing into diodes 36, 37.  Only the even number terms having highest importance in the quadratic term are kept by deciding the sum of the currents flowing into all of the four diodes so as to cancel the odd number terms with one another.

Title: Sawtooth wave generating circuit
Inventor: CHITOU YASUO
IPC: H03K4/50
Filed: 1983-11-30
Abstract: PURPOSE:To produce the stable sawtooth waves at high and low temperatures and over a wide range of power supply voltage, by using the output of an operational amplifier as the reference voltage of a constant current circuit. CONSTITUTION:The output of an operational amplifier OP-1 is supplied to the collector and base of a transistor TR1 as well as to the base of a TR2 through a resistance. A series of loop is formed with the amplifier OP-1, TR1-TR4 and a resistance R2. The both-terminal voltage of the charging current control resistance R2 is equal to the value of the emitter current of the TR4 and therefore equal to the constant voltage KV1 by a negative feedback function of said loop. Thus a charging current I is equal to KV1/R2, and not only the intervention of VBE (TR1) is unnecessary but the TR4 has no direct relation with the charging. This eliminates both the temperature dependence and the voltage dependence. Then an active waveform of II is obtained by the function of a discharging circuit consisting of a TR5.

Filed: 1985-10-11
Abstract: PURPOSE:To attain the fine up-down control of the set numerical value without using any extra rotary dial by increasing and decreasing the frequency, etc. with the clockwise and counterclockwise operations of keys set at the periphery of a keyboard in a dial mode. CONSTITUTION:The keys on a keyboard 1 are operated clockwise and counterclockwise to increase and decrease the frequency or the channel number respectively.

Title: Job scheduling control system
Inventor: SHIMAMURA MITSURU
IPC: G06F9/46
Filed: 1987-09-09
Abstract: PURPOSE:To set a TAT ratio of each job approximate to the target value by carrying out the jobs by allocating a job of a class having the maximum relative value between the estimated TAT ratio and the target one which are calculated for each job class when an idle initiator is available. CONSTITUTION:A job schedule mechanism 11 calculates the data on a job schedule control table 12 and replaces them every time a computer system receives a request for a batch job or this batch job is through. When the job allocated to an initiator 5 is through and an idle initiator is available, the mechanism 11 selects a job of a class having the maximum relative value between the estimated TAT (processing time) and the target one which are calculated for each job class out of a job execution queue 8. Then the selected job is allocated to the idle initiator 5 and carried out. Thus it is possible to change dynamically a job schedule in a job executing state for execution of a scheduling job so that the TAT ratio of each job is set approximate to the target TAT ratio.
