Title: Measuring device for percentage of moisture content of cereals
Inventor: UCHIKAWA YASUO
IPC: G01N33/10
Filed: 1980-12-22
Abstract: PURPOSE:To enable removing of cereals fracture pieces adhered to an electrode, by a method wherein a measuring electrode is placed pivotably. CONSTITUTION:With a motor 16 run in a positive direction, a first axle turns through gears 17 and 18. A cylinder 8, engaging the teeth formed along the axle direction of the axle 14 and screwing-in a screwed hole in a securing member 13, advances in a direction of an arrow mark b through the rotation of the cylinder 8. The rotation of the first axle 14 is transferred to a second axle 19 through a piston 9 and a sector gear 25, and the second axle 19 turns by a given angle. At a point of time when the first axle 1 advances to an advance limit, an electric resistance value of cereals positioned between the nip formed by electrodes 34 and 36 is measured to compute a percentage of moisture content. After measuring is completed, with the motor 16 run reversely, the first axle 1 is moved backward as it turns. Then, the sector gear 25 turns through the energizing force of a coil spring 32. Like this, the electrode revolvs about the axis before and after the measurement, and this enables cereals facture pieces adhered to the electrode to make contact with cereals flowing in a cereals flow path 38 and permits the removal of them.

Filed: 1988-07-20
Abstract: PURPOSE:To reproduce all input pictures with high qualities by making the quantizing method for data for low-density ink different from the method for other data. CONSTITUTION:Density data from a picture input section 1-a are inputted to a look-up table(LUT) 1-b and density data for thin and thick ink are outputted at the timing from a timing clock generation circuit 8. The density data for thin ink are inputted to a relational operator 2 where the data are compared with comparison data from a dot design matrix 3 and further inputted to a delay circuit 7 where the data are quantized by a dither method. The density data for thick ink are inputted to an adder 4 and outputted from the adder 4 after the error outputted from a relational subtractor 5 at the timing of clocks is added to the data and binarization is performed on the output by an error diffusing method. Therefore, gradation and resolution can be compatible with each other and all input pictures can be reproduced with high qualities.

Filed: 1981-11-16
Abstract: PURPOSE:To decrease the number of pins of an IC without increasing the power consumption nor giving any radio disturbance, by providing a control key switch for multiple functions which is operated simultaneously and with a selective combination with control key switches. CONSTITUTION:A logic control IC contains output pins T1-T3 and key input pins K1-K3, and the control key switches S11-S16 of a recorder are connected in a matrix form between those pins. A key switch S17 is connected to the pins T1 and T2 via the diode miserasion preventing switches S18 and S19. The output pins T1, T2 and T3/K1 keep level 1 until the key input is given from corresponding switches S11-S16 excluding the switch S17. At the same time, the output pulses are received from the pins T1 and T2 when the S17 is operated and then fed to the pin T3/K1. Thus the IC works with the inputs of the switches S11- S16 and then reset to its static state. As a result, no radio disturbance occurs although the number of pins is reduced.

Abstract: PURPOSE:To obtain a binarization image to exactly express an object by limiting a light beam made incident on an image pickup device, detecting the maximum peak of an image signal and controlling the operation of an incoming light limiting means so as to be smaller than an upper bound value which is prescribed in advance so that a halation can not be generated. CONSTITUTION:An image signal SP outputted from a TV camera 14 is supplied to a peak deciding device 16 and an image binarization comparator 18. The peak deciding device 16 detects the maximum peak value of the image signal SP to constitute one screen and decides whether the maximum peak value is smaller than the upper bound value prescribed in advance or not. Such an upper bound value is a value as large as possible out of the voltage values of the image signal SP not to generate the halation and when the maximum peak value of the image signal SP is smaller than the upper bound value, the halation is not generated. Accordingly, in such a case, the image signal SP is outputted, as it is, from the peak deciding device 16 to an image signal level detector 20.
