Title: Electrolytic ion water forming device
Inventor: UKITA SHIGETSUGU
IPC: C02F1/46
Filed: 1989-09-26
Abstract: PURPOSE:To allow the continuous use of portable water without impairing the electrolytic effect thereof by providing a control circuit which repeatably impresses a DC voltage to electrodes while inverting the polarity of the DC voltage to be impressed for a short period of time at every prescribed time until a pressure switch is turned off by water feeding and repeats this operation. CONSTITUTION:The pressure switch 9 is turned with a diaphragm 8 by a water pressure in the state of supplying the potable water in an electrolytic cell 1 and the DC voltage is impressed to the two electrodes 2, 3 via a means 10 for impressing the DC voltage and the control circuit 11 while the polarity of the DC voltage is inverted for the extremely short period of time at every prescribed time to form the ion water. The ordinary anode electrode 2 turns to cathode and forms the ion water contg. many cations when the polarity of the voltage inverts, but the inversion time is extremely short and, therefore, the anion water is formed. This operation is reversed on the normal cathode electrode 3 side. The scale sticking to the electrodes 2, 3 is, therefore, eluted and washed at every reversing when the polarity of the DC voltage to be impressed to the electrodes 2, 3 is reversed. The sticking of the scale is thus suppressed and the ion water is continuously formed without impairing the electrolytic effect of the potable water.

Title: Permanent magnet
Inventor: UCHIDA KIMIO
IPC: C22C19/07
Filed: 1988-10-04
Abstract: PURPOSE:To reduce the sintering temperature dependency of a permanent magnet so as to stably manufacture the permanent magnet by mixing Co with specific principal constituent elements contained in specific weight percentages. CONSTITUTION:This permanent magnet contains 22-28wt.% R (R: rare earth elements), 10-25wt.% Fe, 1-6wt.% Cu, and 0.2-5wt.% M (M: at least one of Zr and Hf), and 0.01-1wt.% B. When the adding quantity of B is >=0.01wt.%, the break the second quadrant disappears and the angularness is improved, but, when the quantity is >=1wt.%, the density of residual magnetic fluxes considerably drops and no merit can be expected from the addition. Therefore, the adding quantity of B is limited within the range of 0.01-1wt.%. Moreover, when the adding quantity of rare earth elements is <22%, no sufficient coercive force is obtained, but, when the quantity is >28%, the density of residual magnetic fluxes drops. From the above, the angularness of the second quadrant of this R2C17 permanent magnet is improved.

And a strain gage 10 detects a strain for a fixed time. From this strain, the control device M decides completion of the lapping. Consequently, an automatic detecting device uniformly finishes a size of the lapping and saves its labor.

Title: Measuring device having power source controlling function
Inventor: ENOMOTO MASAHITO
IPC: H02J1/00
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a measuring device capable of reducing power consumption in the case the device is left as power on and immediately returning to the measurable state for use. SOLUTION: If the measuring device (surface roughness-shape measuring device) is left without any operation for a predetermined time as power is on, the power of back light (LCD back light 34) of LCD 32 becomes an off-state to be a sleep state. However the power of an analog detection circuit (differential transformer of pickup 10) maintains on-state even in the sleep state. By this, even if the device is left as power on, power consumption is kept small and measurement can be restarted immediately in the case of reuse of the device.

IPC: G05D1/02
Filed: 1987-10-08
Abstract: PURPOSE:To improve the traveling performance of a motor-driven vehicle on a junction route by obtaining an offset value out of the output of a sensor right before the vehicle moves toward the junction route and therefore suppressing the influence of a switch changeover action. CONSTITUTION:When a sensor detects a mark on a junction line, the input of a holding circuit 111 obtained right before the mark is detected is sent to the output of the circuit 111 for a fixed time. Thus the offset value DELTAx is obtained as the output of an attenuator 112. Then the position detecting value x0 is obtained from the value DELTAx and the output of either one of magnetic sensors 102 and 103.

Title: Pachinko ball (pin ball) counting mechanism
Inventor: SAITO HIROSHI
IPC: A63F7/02
Filed: 1989-09-28
Abstract: PURPOSE:To prevent the occurrence of an error in counting by a method wherein simultaneously with release of the recessed part of a lock cam from engagement by means of the protrusion of a lock lever, rotation of a count plate is rapidly accelerated, and beams passing through the notch part of a disc is caused to instantaneously pass an intermittent boundary line. CONSTITUTION:A protrusion part 51 of a lock lever release cam 5b pushes up a slide contact part 8b of a lock lever 8. When a protrusion 8a of the lock lever 8 releases a lock cam recessed part 61 from engagement, the accumulated resilient force of a coil spring 7 causes acceleration of rotation of a count plate 6. Beams passing through a notch part 6b of a disc 6c are instantaneously shut off to turn ON a sensor 60. The count plate 6 is further rotated and the protrusion 8a of the lock lever 8 is engaged with the next lock cam recessed part 62. When the protrusion 8a is released from engagement by means of a protrusion part 52 of a release cam 5b, the accumulated resilient force of the coil spring 7 throttled through rotation operation of a gear 5 causes acceleration of the count plate 6, beams shut off by the disc 6c instantaneously pass the notch part 6b, and the sensor 60 instantaneously passes the notch part 6b to turn OFF the sensor 60.
