A switch 10 switches the local oscillating signals to be applied to the mixers 1 and 3 to be connected to the N and C sides in the active mode and caliburation mode respectively. When the amplitude characteristics of outputs 8 and 9 are referred to as A and Adelta respectively, the outputs become Acosphi/2 and Adeltasinphi/2 in the active mode and Asinphi/2 and Adeltacosphi/2 in the calibration mode, respectively. Thus delta can be obtained from these output values.

IPC: B41J2/06
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic attraction type ink jet recorder in which recording can be performed stably through a simple structure. SOLUTION: A photoconductive layer 12, a float electrode 14, a dielectric layer 13, and first and second electrodes 11a, 11b which are arranged, outside the photoconductive layer 12 and the dielectric layer 13 are laminated to constitute a photosensitive device section A.

An ink carrier 15 having a slit 15a is arranged on the float electrode 14 and the pointed head part 14a is covered with ink. When the photoconductive layer is irradiated with a laser light modulated by image information, electric resistance decreases in the photoconductive layer at an irradiated part and a potential appears between the float electrode and the back electrode at the irradiated part to generate a micro corona discharge. Consequently, the ink is converted into a micro liquid drop which flies toward the back electrode and adheres to a recording sheet C, thus recording an image.

Inventor: KANEKO SEIJI
IPC: G06F3/05
Filed: 1982-03-17
Abstract: PURPOSE:To ensure the effective use of the instruction executing time of a CPU, by storing an input data directly to a memory without obeying a command given from another circuit, and at the same time processing the data through a CPU. CONSTITUTION:An input control circuit 12 works despite the command of a CPU1 and applies a sample holding signal 5b to a sample holding circuit 6 to sample and hold the quantity of input electricity. The sample-held signal undergoes an A/D conversion and is stored temporarily in a memory 11. Meanwhile it requires a response time (t) for rearrangement of data, exchange of data, processing of queuing time, etc. The circuit 12 applies an interruption to the CPU1 in accordance with storage of the input data, and the CPU1 processes the data of the memory 11. The data of the memory 11 is stored in an RAM2 when it is desired to prevent the rewriting of the contents of the memory 11 during operation of the CPU1. Thus the CPU1 can perform the data processing of operation, etc. even while the data is written to the memory 11.

Filed: 1986-02-28
Abstract: PURPOSE:To obtain a high frequency inductive coupling plasma-mass spectrometer of high sensitivity by generating the discharge by a fixed voltage applied the electrodes provided near the top of a skimmer. CONSTITUTION:When a fixed voltage from a variable voltage power supply 53 is applied to the electrodes 52, electrons are accelerated toward the electrodes 52 and energy of the electrons become greater than ionization energy of surrounding electrons.

Abstract: PURPOSE:To obtain J-FET of high gm at high yield, by laminating channel-use thin n-epitaxial layer and gate-use p-epitaxial layer on p-type substrate and diffusing source and drain which extend from the surface to the channel. CONSTITUTION:Channel-use n-epitaxial layer 7 with specific resistance of approx. 1OMEGAcm is laminated on p-type substrate 1 with specific resistance of approx. 5OMEGAcm as thin as approx. 1mu and then p-epitaxial layer 8 with specific resistance of approx. 0.1OMEGAcm is further laminated to make gate layer. With surface oxide film 9 as mask, n-type source 4 and drain 5 are diffused and connected to the n-layer 7. Now, as the p-type substrate 1 and the p-layer 8 are higher in density than the n-layer 7, the heat treatment allows occurrence of diffusion toward the n-layer 7, and therefore, by utilizing this diffusion, punch through voltages of the substrate 1 and the gate layer 8 are measured to control channel high a. And then, electrodes 10 and 11 are attached. J-FET of this structure has extremely small fluctuation of channel hight a and uniform distribution of drain current. Further, it is possible to satisfactorily shorten space between source and drain, widen gate width and highten gm so that production yield can be improved.

Abstract: PURPOSE:To obtain an automatic liquid sampler of good reproducibility while retaining the advantage of a hermetically closed sample bottle by providing an air guide for an air hole in a sample vessel into which the needle of an introducing device such as micro-syringe is inserted aside from the syringe in said sample vessel. CONSTITUTION:At the time when a micro-syringe 6 sucks the liquid sample 21 in a sample bottle 12, it lowers together with a syringe support 7, and the leading end of a needle 25 is inserted into a rubber cap 18. A spring 17 is compressed as it is pressed by the descending support 7, whereby a syringe guide 9 is lowered as well. An air guide 19 is inserted into the cap 18 aside from the tip of the needle 25. The guide 19 is made into a pipe shape and permits in and out of air even when it is inserted into the bottle 12 through the cap 18. No air bubbles remain in the syringe in spite of suction of a set volume after a number of times of repetition of the suction and discharging of the sample in the bottle 12. According to this device, errors of reproducibility are improved up to about 2% while the advantage of the absence of the evaporation of the sample is retained.
