Title: Hot wire type air flow rate measuring device
Inventor: SUGIURA NOBORU
IPC: G01F1/698
Filed: 1981-04-14
Abstract: PURPOSE:To detect an air flow rate accurately by extracting a current flowing from a bridge circuit, including a hot wire and a cold wire, to the hot wire, and processing the level of the extracted current as data which shows a flow rate directly. CONSTITUTION:When an air flow rate in a bypass air corridor 22 varies, auto- matic balancing operation is performed to the resulting resistance variation of a hot wire RH. As a result, a current IA flowing through the hot wire varies according to the function of the air flow rate. The current IA is led into a car room to flow a resistance R3. Therefore, a voltage drop which corresponds to the function of the air flow rate is generated across the resistance R3, and at the input of an amplifier AMP, a signal AP showing the air flow rate appears. This signal AF is used for prescribed control operation in a control circuit 60.

Title: Control unit for magnetic flux
Inventor: ORIME SHINKEI
IPC: H01P1/195
Filed: 1979-05-04
Abstract: PURPOSE: To prevent the malfunction of comparator due to noise, by discharging the integrating circuit which produces the output signal proportional to the change in magnetic flux, other than setting.  
     CONSTITUTION: The terminal Q' of the set D-FF5 and the terminal of discharge circuit 20 are connected as shown in chained line T, and the discharging of the ingetrator 17 is made at both of reset start and set end. That is, since each output of the terminal Q' and terminal Q of FF5 is inverted logic each other, the output of the terminal Q' of FF5 at the end of set is inputted to the circuit 20 the same as discharging at reset. With this constitution, since the output of the integrator 17 other than reset is always zero, even if a little noise is superimposed on the output of integrator at the eset-set time band of D-FF, the noise is low in level than the phase control signal level. Accordingly, the malfunction of the comparator 18 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent the washed away of internal borrow by the wave motion in a flood by forming the surface of a bag body for housing borrow in raising state, housing the borrow in the bag, and laying the bag on ground surface. SOLUTION: When a borrow bag body for housing eatyth and sand, planting bed, fertilizer, seeds and the like is formed of a rough-mesh fiber, and laid on the inclined surface of a river, the probability of the content being sucked by wave motion is increased. Therefore, the surface of the bag is made in raising state, and a polyester fiber or hemp is used as part of the fiber, for example, before sewing. A brush is brought into contact with the sheet surface to raise the surface by friction, and the sheet is sewed into a bag state to manufacture a bag body having an opening part on one end. A borrow consisting of a mixture of earth and sand, fertilizer, seed and the like is put in the inner part, and the opening part is blocked. The bag body containing the borrow is laid on the ground surface.  Thus, this bag can be utilized for revetment means of river, lake, dam and the like, or a water retaining effect most suitable for planting can be provided.

Abstract: PURPOSE:To prevent part of an observing beam from superposing on the reflected beam and entering an observing device by simultaneously sending the laser beam and observing beam by mutually parallel two reflecting mirrors and separating and reflecting the both beams. CONSTITUTION:The 1st reflecting mirror 24 and 2nd reflecting mirror 26 are placed parallel. The surface 24a of the 1st reflecting mirror opposing to the 2nd reflecting mirror is a multilayer vapor-deposited film mirror, on which a laser beam 22 reflects totally but an observing beam 32 transmits therethrough. The opposite surface 24b is a vapor-deposited film mirror, on which the observing beam 32 reflects totally. The surface 26a of the 2nd reflecting mirror opposing to the 1st reflecting mirror is a vapor-deposited film mirror and its opposite surface 26b is a multilayer vapor- deposited film mirror. Because of this, the laser beam 22 from a laser working apparatus 21 reaches the work 29 like the solid line. On the other hand, the observing beam 32 from an observing light source 11 reaches the work 29 like the dotted line and the reflected beam 34 enters an observing device 35 through a semitransparent mirror 33. The two beams are separated and reflected in this way, hence ''fog'' phenomenon and the like in the observing device do not occur.
