Title: Camera provided with blurring detection device
Inventor: ODAKA YUKIO
IPC: G03B7/30
Filed: 1990-02-05
Abstract: PURPOSE:To make it possible that a photographer recognizes a detection state for himself by detecting reliability in the detection of vibration by a sensor and displaying the decided result when the reliability is low. CONSTITUTION:When a blurring detection mode is selected, a microcomputer PRS fetches a signal output from a line sensor device SNS and calculates the deviation of an SNS-1a(a central vertical sensor). A difference between the accumulated image signal at this time and the accumulation signal at the previous time of the sensor SNS-1a is measured to obtain the deviation. Then, whether both of the SNS-1 and an SNS-4(a central horizontal sensor) are in a state where detection can be possible or not is decided. When the detection is impossible, such an effect is displayed on a display member DSP through a display circuit DDR. Therefore, the photographer can previously recognize whether a blurring limit time is set or not.

IPC: G06F12/00
Filed: 1989-02-06
Abstract: PURPOSE: To store a related data base on a recording medium by making a table include plural continuously and serially arranged records and making the records include plural data records and plural column descriptor records. CONSTITUTION: By starting a new data record after an arbitrarily variable length or blank possible data field, any column is compressible if the column is the last column within the data record. The beginning of this field is discriminated by a column descriptor record and the end of this field is discriminated by the preceding blank mark or the length mark within the plural data records. It is preferable that only a blank possible or variable length field having the maximum length which is longer than an arbitrary constant is compressed. For instance, such a constant can be made equal to the longest length of an arbitrary supported numeric value. Thus, when a data item is blank or is the shorter than the maximum length, a file compression becomes possible.

Abstract: PURPOSE:To generate a stable sawtooth wave and to apply the control of a delay time with high accuracy, by providing an error amplifier which inputs a pair of pulse signals with phases opposite to each other to both bases of an emitter-coupling balanced switching circuit and furthermore, controls the base potential of the sawtooth wave at a constant level. CONSTITUTION:When an original signal pulse inputted to an input terminal 1 is set at an 'b', and a signal pulse inputted to an input terminal 7 on the other side at an 'H', a transistor Q1 is turned 'OFF', and a transistor Q2 is turned 'ON'. In such a state, a constant current is charged from a constant current source 2 to a recharging capacitor C, then, the sawtooth wave is generated. Next, when the original signal pulse goes to the 'H' and the pulse with opposite phase on the other side goes to the 'L', discharging is performed to the constant level with the supplying current value of a constant current source 5, Then, the error amplifier 6 compares it with a reference voltage VB on one side, and controls the base of a transistor Q3 so as to suppress the base potential of the sawtooth wave at the VB. Therefore, it is possible to obtain the sawtooth wave with high accuracy, and the base potential of the sawtooth wave is controlled at a constant value by the reference voltage VB on which temperature compensation is applied.

Title: Thread-cutting device of sewing machine
Inventor: SAKATANI YASUYUKI
IPC: D05B65/06
Filed: 1994-02-24
Abstract: PURPOSE:To let a loop formed of a needle thread properly get entangled with a bobbin thread to certainly form a stitch at the next stitch by a method wherein a cut end of the bobbin thread that is not caught by a movable knife and a thread holder is fastened to a first guide or to a second guide in the circumferential direction of a rotating hook. CONSTITUTION:When thread cutting actions are sequentially performed, such a thread fastening failure that a bobbin thread 13 is not caught by a movable knife 7 and a thread holder 10 after the thread 13 is cut frequently occurs. At that time, the bobbin thread 13 moves toward the outside of the bobbin thread holder by the return motion of the movable knife 7 and is fastened to a first guide member. Then, the bobbin thread 13 is horizontally held high above the tip of a rotating hook. As the bobbin thread 13 that fails to be caught is in slack state because a specified tension is not applied on the bobbin thread 13, the bobbin thread 13 is likely to adhere on the rotating hook. However, the bobbin thread 13 is caught by a second bobbin thread guide member 5b formed by a recessed part 5c and a shuttle body protrusion 5a. Therefore, the bobbin thread 13 is held above the moving locus of the tip of the rotating hook.
