Title: Offset compensating circuit
Inventor: SUGIZAKI IWAO
IPC: H03F3/34
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To ovoid the effects of variations in source voltage, even at a low source voltage time by inputting the output of a reference voltage generation which is connected between a positive and a negative power source to a 1st differential amplifier and inputting its output to the positive and negative of a 2nd differential amplifier. SOLUTION: An anode of a Zener diode 3 for reference voltage generation is connected to the plus input of a 1st differential amplifier 1 and a cathode is connected to the negative input to obtain and input a stable reference voltage free of the effects of variations of power sources Vcc and Vee as the output voltage of the differential amplifier 1 to attenuating circuits 6 and 7, whose outputs are inputted to adding circuits 8 and 9. The power source voltage variation effects can be avoided by adjusting the attenuation quantities of the attenuating circuits 6 and 7, so that the offset voltage generated when there is no cross-linking magnetic flux to a Hall element 5 is canceled.  The anode and the cathode of the Zener diode 3 are passed through a constant-current circuit 10 to input a constant current to a terminal 11 of the H all element 5 and the power source Vee to a terminal 13, and this is driven with the constant current to stabilize temperature characteristics.

Inventor: SASAKI HITOSHI
IPC: G01N9/18
Filed: 1992-11-02
Abstract: PURPOSE:To prevent error factors from being taken into measurement results to highly accurately measure density of various kinds of high temperature melted liquid. CONSTITUTION:Bobs 15, 17 are hung via wires 11, 16 from a weight 12 with a hook 13 hooked on a thread 15 hung from a balance 14. The upper bob 10 also can serve as the weight 12. Coating inactive to melted liquid 19 to be measured may be applied to the bobs 10, 17 and the wires 1, 16. Thus the bobs 10, 17 are forced to be soaked in the melted liquid 19 to be measured via the wires 11, 16 free from influence of difference in specific gravity from that of the liquid 19, wettability to the liquid 19 or the like. Therefore density of various kinds of melted liquid can be measured. In addition it is possible to calculate density of the melted liquid 19 from a weight of a measuring device when the lower bob 17 is soaked and weight of the measuring device when both bobs 10, 17 are soaked without being influenced by surface tension of the liquid 19 to the bobs 10, 17 and the wires 11, 16.

Title: Local picture processing method
Inventor: ORITA MIYAHIKO
IPC: H04N1/409
Filed: 1987-12-18
Abstract: PURPOSE:To make the outline or boundary of a pattern clearer by processing the density of each point at a part where the density of the outline of an objective pattern smoothly changes as the nearer value of the maximum and minimum densities in the vicinity of the point. CONSTITUTION:An original picture F becomes a picture FS after it is smoothed by (n) times at a smoothing circuit 1. A maximum value circuit 2 produces a picture FX by performing maximum value processes (m) times on the picture FS. A minimum value circuit 3 produces a picture FN by performing minimum value processes (m) times on the picture FS. Subtractor circuits 4 and 5 find the difference FXS between the pictures FX and FS and the difference FSN between the pictures FS and FN and a subtractor circuit 6 calculates the difference G between the differences FXS and FSN. Deciding circuits 7-9 produce binary pictures G-, G0, and G+ which respectively become '1' when G<0, G=0, and G>0. AND circuits 10-12 perform masking processes on the binary pictures by using the pictures FX, FS, and FN. When the OR of the outputs of the circuits 10-12 is taken by means of an OR circuit 13, a processed result Fout which is a picture, from which obscure outlines are removed, is obtained.

Title: Focusing controller
Inventor: KATASE EIJI
IPC: G02B7/28
Filed: 1991-12-03
Abstract: PURPOSE:To enable accurate focusing control by selecting a weight coefficient when a high brightness part is in existence in a picked-up object so as to reduce the degree of contribution of a high frequency component to a direction discrimination value due to the high brightness part. CONSTITUTION:A high brightness detection circuit 9 detects information relating to whether or not a scanning line in a sample area is in crossing with a high brightness part in a picked-up object formed on an image pickup face of a CCD 2 for each scanning line and outputs the result to a microcomputer MC11. The MC11 selects a weight coefficient when the high brightness part is in existence in the picked-up object to decrease the contribution of the high brightness part to the direction discrimination of the high frequency component thereby increasing the contribution of the direction discrimination value of the high frequency component based on a contrast of the image pickup object other than the high brightness part. Thus, mis-discrimination of the focal position due to the increase in the high frequency component of the high brightness part is avoided and an unnatural movement of a focusing lens 1 for each scanning frame is eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide a matrix type liquid crystal display device arranged to secure an excellent display performance without adopting a temperature sensor but by making use of the fact that a wave distortion of an impressed scanning voltage on scanning electrodes has a certain relation with a temperature of the liquid crystal. SOLUTION: When a scanning voltage is impressed on scanning electrodes X of a liquid crystal panel 10, a differential amplifier 50 amplifies differential voltages arising across both ends of these scanning electrodes X.
