Title: Cloth hem following sewing machine
Inventor: HORIE FUJIO
IPC: D05B21/00
Filed: 1987-07-03
Abstract: PURPOSE: To form a straight stitch line with a final sewing position in copy sewing as a base point by forming stitches copying a cloth edge, operating an operation member, inhibiting the updating of the stored contents of a storage means by a sewing inhibition means and supplying the needle position control signal of a previous time to an actuator. CONSTITUTION: In the case that a cloth edge position fluctuates, since detection signals from a cloth detector 54 do not match with reference signals from a variable resistor 112, error signals from a comparator 114 are not zero anymore and they are converted to digital signals in an A/D converter 116 and supplied to an adder 118. During the operation of a sewing machine, since a timing pulse from a timing pulse generator 88 is supplied through an OR circuit 122 to the adder 118, the adder 118 adds the digital signals from a latch 120 and the digital signals from the A/D converter 116 corresponding to the input of the timing pulse. The positions of a needle bar base and a sewing needle are changed so as to match the detection signals from the cloth detector 54 with the reference signals from the variable resistor 112.

Title: Core bit for core drill
Inventor: HIRATA YOSHIKI
IPC: B28D1/14
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent slip of a body at the time of grasping it by forming a non-slip means not protruding from a surface on a surface of the body. SOLUTION: A non-slip means not protruding from a surface is formed on a surface of a body 21. As the non-slip means, any means for performing a function as non-slip at the time of grasping it may be formed at any part of the body 21. Here, three strips of circumferential grooves 22 are formed at an upper side part of the body 21, and wear due to introduction of cutting chips to the non-slip means is reduced almost without influence of contact with or perforating a concrete structure at the time of perforating. Since the body 21 is grasped in this manner, the core bit can be relatively stably carried or supported. Further, since a part formed with the non-slip means of the body 21 is grasped by one hand or both hands to be scarcely slipped, carrying of the core bit or mounting of a drill head at an output shaft is facilitated.

Title: Glow control device for diesel engine
Inventor: SUZUKI YUTAKA
IPC: F02P19/02
Filed: 1984-08-11
Abstract: PURPOSE:To improve combustibility of an engine and reduce its noise and vibration, by detecting a delay time of firing in injected fuel and electrifying a glow plug when the delay time of firing increases longer than a predetermined time. CONSTITUTION:When a Diesel engine 10 is started by turning on a power supply, an electronic control device 20 first calculates a speed on the basis of the output of a crank angle reference signal detector 17. Next the device 20, under a condition electrifying a glow plug 14, calculates both a permissible delay time of firing, when the flow is electrified, from a two-dimensional map of a speed and injection timing and an actual delay time of firing on the basis of an output from an injection timing detector 22. Subsequently, the device 20, comparing this actual delay time of firing with the permissible delay time of firing, outputs an on-signal for electrifying the glow plug 14 when the former time is larger than the latter time while an off-signal for cutting off the electrification to the glow plug 14 when the delay time is in a reverse relation.

Title: Moisture measuring apparatus for grain
Inventor: KANEKO AIJIRO
IPC: G01N27/04
Filed: 1986-07-17
Abstract: PURPOSE:To measure moisture of grain without switching measuring range, by connecting an element having a logarithmic characteristic in the voltage vs current relationship to a circuit in an apparatus which grasps a grain between a pair of electrodes to measure moisture thereof from current signals thereof. CONSTITUTION:A fixed voltage is applied to a pair of rolls 1 and 1' grasping a grain and inputted into a detection circuit 3. The detection circuit 3 has diodes D1 and D2 with a logarithmic characteristic in the voltage vs current relationship forward connected in series to a low resistance R1 and a high resistance R2 respectively while the diodes D1 and D2 are connected in parallel to maintain them at a fixed temperature. A voltage (e) is applied across a terminal of the high resistance R2 and amplified with an operational amplifier 4 to be an output voltage e'. Then, when current on the side of the low resistance R1 is represented by I1, current on the side of the high resistance R2 by I2 to express the total current I by I=I1+I2, the current I2 can be held less even against a large change in the current I, for example, about 2,000 times when the current I such changes as large as about 100,000 times and hence, current changes can be detected. Thus, the connection of the diodes with a logarithmic voltage vs current relationship enables the measuring of moisture of grain at a high range without switching measuring range.
