Title: Electrophotographic developing method
Inventor: TERASAKA YOSHIHISA
IPC: G03G15/09
Filed: 1990-07-12
Abstract: PURPOSE:To properly control toner concentration regardless of toner replenishing frequency and to reduce the fogging of an image and the scattering of toner by using resin coated carrier having many pores on its surface. CONSTITUTION:Two-component developer consisting of magnetic carrier 21 and toner 25 is used, and an electrostatic latent image is developed while the magnetic permeability of the carrier 21 is measured and the toner concentration is controlled. Then, the resin coated carrier having many pores 24 on its surface is used as the carrier 21. For example, an offspring particle for forming a coating layer is obtained by mixing ferrite fine powder and bisphenol type polyester resin and kneading and cracking them. Next, sintered ferrite powder as a carrier core material 23 and the offspring particle are mixed and stirred, so that the offspring particles are uniformly stuck around the core material 23. Then, the respective particles are dispersed and supplied in a heated air current and momentarily heated so as to form the coating layer 23. Consequently, a positive charge control agent is stuck to the coating layer, so that the carrier 21 having the pores 24 on the surface is obtained.

IPC: G01N33/72
Filed: 1990-07-11
Abstract: PURPOSE:To carry out the hemolytic dilution of an erythrocyte-containing sample for setting the conc. of hemoglobin to a definite range by controlling the injection of a hemolytic diluent until reaching prodetermined absorbancy on the basis of the electric signal from an absorption photometer. CONSTITUTION:A nozzle 72 for a sample to be examined sucks a definite amount of the sample to be examined from the blood collecting tube on a blood collecting tube holding stand 71 by operating a pump 73 and moved to a hemolytic dilution sample preparing tank 1 to inject said sample in the tank 1. Subsequently, a diluent nozzle 4 sucks a hemolytic diluent from a diluent tank 3 by operating a diluent pump 5 to inject a predetermined amount of the diluent in the preparing tank 1 to carry out the hemolytic dilution of the sample to be examined. The absorbancy of this sample is measured by an absorption photometer 2 to be compared with a preset upper limit value. When the absorbancy is higher than the upper limit value, a definite small amount of the diluent is added by the nozzle 4 until the absorbancy becomes equal to or less than the upper limit value and this operation is repeated. These pumps 73, 75 and nozzles 72, 74 are electrically connected to a control part 6 to be controlled in driving and a hemolytic dilution sample with constant conc. is prepared.

Filed: 1984-09-04
Abstract: PURPOSE:To make it possible to detect the generation frequency of a Karman vortex from a low flow amount region to a high flow amount region, by altering the amplifying ratio of an AC amplifier for amplifying a vortex signal corresponding to the sucking amount of air. CONSTITUTION:A hot wire type vortex detector 2 is arranged in the downstream side of the vortex body placed in a flowline and a current is supplied to said hot wire type vortex detector 2 by a current amplifier 7. A bridge circuit 1 generates an output signal corresponding to the generation frequency of a Karman vortex from the change in the resistance of the hot wire type vortex detector 2 and outputs the same to BPF8 through a differential amplifier 6. BPF8 permits only the passage of vortex generation frequency and supplies said frequency to an AC amplifier 11. The AC amplifier 11 amplifies said vortex signal to output the same to a terminal C through a comparator 17. A change- over switch 13 is provided to the feedback route of the amplifier 11 and changed over corresponding to the output of a flow amount discrimination circuit 14, that is, the sucking amount of air to alter the amplifying degree of the amplifier 11 to the value corresponding to the sucking amount of air.

Title: Method for controlling resistance welding
Inventor: NISHIZAWA KEIJI
IPC: B23K11/25
Filed: 1980-12-29
Abstract: PURPOSE: To discriminate the goodness of welding surely by adding preheating current conduction and cooling period before conduction of welding current, and discriminating the goodness of welding from waveform exhibited by inter-electrode resistance or voltage during welding, and stopping the welding current.  
     CONSTITUTION: Conduction of electricity for the purpose of preheating the work is carried out during t 1 Wt 2  prior to supply of welding current between electrodes. Next, the work preheated by the preheating current is cooled during t 2 W t 3 . Hence, the dirt, oil film, surface treatment film, etc. on the work surface burn out. When welding current is supplied during t 3 Wt 4  in succession to this, the work is heated, and in proportion to this, inter-electrode resistance or voltage rises. During t 4 Wt 5 , the rise of the inter-electrode resistance or voltage saturates and the crest of the weveform is formed, then the formation of nugget begins. At the same time, the inter-resistance electrode or voltage drops, and from the change value of the drop from the peak value, the welding is discriminated to be good, and the welding current is stopped.

Abstract: PURPOSE:To simplify a driving logic design by decreasing a driving pulse, when driving a priming transfer part (CPD). CONSTITUTION:At time t0, optical signal charge is accumulated in a photodiode 102. At time t1, an address pulse 402 is applied to a line 104 from a vertical scanning shift register 101, and signal charge QS which has been photoelectrically converted by the photodiode 102 starts to move to a column line 105. At time t2, an accumulation state of an optical signal is obtained. At time t3, priming charge QP is injected to the column line 105 through a gate 106 from the accumulation part. At time t4, both the charge QS and the charge QP are moved  to the accumulation part. At time t5, only the charge QS is fetched to a horizontal CCD113. At time t6, the skimming transfer is completed, and when the signal charge QS which has been skimming-transferred to the CCD113 enters a horizontal period, it is transferred toward the signal output transfer part by a pulse 401.
