Title: Distance measuring device of camera
Inventor: HASHIMOTO NOBUO
IPC: G03B3/00
Filed: 1978-12-16
Abstract: PURPOSE: To judge whether the subject is of the luminance suited for automatic focusing operation or not by comparing the change rate of the absolute value of the detected two signals difference for distance measurement with a set value and judging the suitability of the luminance.  
     CONSTITUTION: The two detection signals for focusing detected by two sets of photoelectric transducers 7, 8 is applied via difference detecting circuit to an absolute value circuit 11. The differential absolute value is differentiated by a differentiating circuit 12 and the change rate of the differential absoulte value voltage  with time is compared with a set voltage in a voltage comparator 12. When the  subject luminance is above the specified value and the differentiated output of the  absolute value difference is more than the set value, an FF17 is set by the comparing output of the circuit 15, by which an FF18 is set. While the subject luminance  is high, a display lamp 22 is lighted by the high level set output of the FF18. When  the subject luminance is low, the low level output of the FF18 lights a warning  indicator lamp 21 to warn that the subject luminance is inadequate for automatic  focusing operation. Hence, the operation of automatic focusing, etc. of large errors  by the low luminance subject may be stopped.

Title: Resin-sealed type semiconductor device
Inventor: MASUKO KOICHIRO
IPC: H01L23/31
Filed: 1984-07-24
Abstract: PURPOSE:To obtain the titled device of high moisture resistance and high reliability by a method wherein the grain size of the filler in a sealing resin is made smaller than the thickness of a passivation film. CONSTITUTION:The grain size of the filler 9 in the sealing resin 6 is made smaller than the thickness of the passivation film 8.

Title: Lithium battery and its manufacture
Inventor: KIZAKI TAKASHI
IPC: H01M4/06
Filed: 1980-11-06
Abstract: PURPOSE:To equalize the distribution of an electrolyte in a positive electrode body, and enhance the utilization rate of a positive active material by mixing the positive active material and a non-aqueous electrolyte to make the voids of an active material powder to be filled with the electrolyte, and molding thus prepared mixture into the positive electrode body. CONSTITUTION:A positive mixture consisting of a positive active material such as manganese dioxide powder, acetylene black and the like is mixed with a non-aqueous electrolyte such as a propylene carbonate solution of lithium perchlorate, thereby making the voids of the active material powder to be filled with the electrolyte. Thus prepared mixture is molded into a positive electrode body 1, which is placed in a positive can. After that, a separator 2 impregnated with the non-aqueous electrolyte, and a negative electrode 3 are placed over the positive body 1, thereby a battery being constituted. In assembling the battery, the electrolyte is not poured into the positive body 1. By the means mentioned above, the electrolyte is much more homogeneously distributed compared with a battery in which a positive mixture powder, after being compressed and molded, is impregnated with electrolyte. Consequently, the utilization rate of the active material is enhanced without using much electrolyte for the impregnation of the active material.

IPC: H03L7/08
Filed: 1986-07-02
Abstract: PURPOSE:To expand the locking range into a stable and sufficient range if out of synchronism takes place by using an out-of-phase detection means to detect the in-phase state of a phase locked loop thereby changing a loop parameter of the phase locked loop according to the result of detection. CONSTITUTION:Interference wave signals 102, 103 are extracted by a phase locked loop from an input signal 101 including an interference wave component and the amplitude and phase of the interference wave signals 102, 103 are controlled by an amplitude phase control means 3. Then the output of the control means 3 is subtracted from the signal 101 by using a subtraction means 4 to eliminate the interference wave component, and the input signal 101 or either of the interference wave signals 102, 103 and an output of the subtraction means 4 are subject to orthogonal multiplication to obtain a control signal controlling the amplitude phase control means 3. The phase locked loop is constituted by equipping the loop parameter control means whose loop parameter is changed by the out-of-phase signal 104. Thus, if the out-of-phase takes place in the phase locked loop, the locking range is expanded to a stable and sufficient range.

Abstract: PURPOSE:To obtain the manufacture of a semiconductor, which generates a proximity effect and in which the dimensional error of a pattern at the time of exposure is removed, by conducting first exposure by using a reticule, in which a dummy pattern unnecessary on circuit operation is formed around a sparse pattern, and performing second exposure by employing a reticule, in which only the dummy pattern is taken off. CONSTITUTION:A positive type photo-resist 5 is exposed by employing a reticule 6 shaped by patterning chromium on silica glass in order to form a gate electrode pattern. Since dummy resist patterns 9, 10 are formed adjoined to a sparse resist pattern 11 at that time, the pattern 11 receives the same proximity effect as a dense resist pattern 12.

Developing is conducted after second exposure, the dummy patterns 9, 10 sections shaped for the first time are taken off, and a photo-resist pattern is formed. Accordingly, dimensional errors in the sparse and dense patterns 11, 12 can be suppressed to one third or less of conventional devices.
