Abstract: PURPOSE: To eliminate the breakage of a lead due to a strong flexural load during writing by a method in which the shaft core of the writing part of a slider has a metal core guide pipe, a coat layer of resin, etc., which has good abrasion resistance and a small frictional coefficient is formed outside the pipe, a tapered surface is formed at the tip of the writing part. CONSTITUTION: A clamping cylinder 6 is fixed at the tip of a chuck case 2. The front end bore part of the cylinder 6 is formed in the shape of a taper, a lead chuck 3 in which balls 4, 4' contacting the tapered surface are engaged with the recessed part of an outer surface is attached inside, the chuck 3 is pushed backward by a coil spring 5 which is fixed between the chuck 3 and the step part which is formed at the rear end of the cylinder 6. The chuck 3 is formed by combining two divided parts of a cylinder which is a molded article of a synthetic resin having high elasticity and good abrasion resistance. When writing pressure is applied to the lead, the balls 4, 4' are rotated to clamp the chuck by a wedge effect, so that the breakage of the lead can be prevented against a strong flexural load.

Title: Image reader
Inventor: KIMURA SHUYA
IPC: G06T1/00
Filed: 1985-10-25
Abstract: PURPOSE:To prevent the shift of an original position at the time of setting by printing dots on a scale sheet with a drop-out color and placing the scale sheet on a surface opposite to an original platen for retaining an original. CONSTITUTION:The original 3 is put into the scale sheet 1 to insert it. In that state coordinates in an area to which an operator wants to apply a specific processing are read through the use of a cross-section paper printed on the scale sheet 1, and the read values are inputted through a control panel 5. Then, with the original 3 inserted into the scale sheet 1 an original retainer 2 is closed to set the original 3 to the original platen 4, and the original 3 is read by an image reader main body 6. At that time, the section point printed on the scale sheet 1 and a coordinate system used as a reference when the image reader main body 6 scans the original platen 4 are set so as to properly overlap when the original retainer 2 is closed. Thus the trouble at the time of setting an original is omitted, and besides the shift caused by setting an original can be prevented.

Title: Malfunction preventing circuit for memory card
Inventor: ADACHI KEIICHI
IPC: G06F1/00
Filed: 1987-09-24
Abstract: PURPOSE:To effectively prevent the destroy and the malfunction of a memory card by controlling with high impedance the output of an input buffer in the input signal indefinite period of the input buffer generated when the memory card is attachment/detachment-operated to and from a main body side connector. CONSTITUTION:For example, when a memory card 2 is pulled out of a main body 1, a microswitch SW transfers from an ON to an OFF, therefore, an enable control terminal 12 is cramped at low level and a try state buffer 4 does input a high output impedance condition. Thereafter, even when the contact of signal pins 10a and 11a with 10b and 11b is released and at the indefinite period, the buffer 4 is in the high output impedance and therefore, the output of the buffer 4 does not exceed a power source voltage from a memory part 3. Thus, the malfunction at the time of attachment and detachment can be prevented and the danger of the destroy of the memory part is eliminated.

Title: Method and apparatus for detecting abnormality of flow rate sensor
Inventor: YAMAURA MICHIAKI
IPC: G01F1/68
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To judge an abnormality of a flow rate sensor based on an output state of the sensor, eliminate special detecting sensor and detecting circuit and recognize the abnormality easily, surely by confirming consecutively by a predetermined number of times that the number of oscillations for a predetermined time of one of a pair of temperature sensors is 1. SOLUTION: A sensor abnormality-judging circuit 41 detects the number of oscillations for a predetermined time of oscillation circuits 23, 24 of temperature sensors 21, 22 at the upstream side and downstream side, judges whether each number is 1 or not, and operates a flow rate from a difference of the numbers when neither is 1. On the other hand, when each number is 1, it is doubted that a low flow rate sensor is abnormal. When the number of times (n) is a predetermined number N, the judging circuit 41 judges that the low flow rate sensor is abnormal. Similarly, the judging circuit 41 judges the presence/absence of oscillations of a high flow rate sensor 31. Without any oscillation, the judging circuit detects an oscillation frequency and doubts that the low flow rate sensor is abnormal if the oscillation frequency shows a predetermined frequency difference. Since an abnormality of the sensors is judged by the number of oscillations for a predetermined time, no special detecting means is required.

Title: Ultrasonic flow meter
Inventor: MATSUDA YASUO
IPC: G01F1/66
Filed: 1984-11-16
Abstract: PURPOSE:To take an accurate measurement even if the temperature of fluid varies by detecting the temperature of the fluid from the propagation time of an ultrasonic wave which is propagated without passing through a flow of the fluid and determining the quantity of correction, and correcting a calcu lated flow rate by using the propagation time difference. CONSTITUTION:An ultrasonic wave radiated by one of ultrasonic oscillators 1 and 1' crosses a pipe 4 in which the fluid 3 flows at a specific angle and is reflected by the internal wall of the pipe 4 reaches the other at a specific angle. For the purpose, the oscillators 1 an 1' are arranged across wedge members 2 and 2'. The electric signal from a transmission part 5 is supplied to the oscillator 1 through the solid-line position of a changeover switch (S) 6a and the propagation time T1 of the measured ultrasonic wave is stored in a storage circuit 8. Then, the propagation time T2 when the S6a is switched to a broken-line position is stored in a storage circuit 8. Further, the propagation time Tp of the ultrasonic wave propagated in the pipe 4 through a route lis measured by a measuring circuit 14. The flow rate calculated from the times T1 and T2 is corrected with the time Tp to measure the flow rate. Consequently, the flow rate is measured accurately even if the temperature of the fluid varies.
