Title: Magnetic scale and its forming method
Inventor: WAKIWAKA HIROYUKI
IPC: G01D5/245
Filed: 1990-05-19
Abstract: PURPOSE:To constitute a magnetic scale by overlapping an amorphous thin film on the surface of a metal substrate, performing laser welding along a desired pattern or pitch lines, slowly cooling the welded parts, and crystallizing the welded parts. CONSTITUTION:An amorphous thin film 2 is overlapped on the surface of a metal substrate 1. Laser welding is performed along a desired pattern or pitch lines. The welded parts are slowly cooled, and the thin film 2 is fixed to the surface of the substrate 1. A crystallized region 3 as a result of the slow cooling of the laser welded lines which are formed on the thin film becomes a section wherein permeability is decreased with respect to another thin film region 4. Thus, a magnetic scale is formed. Namely, since the welded lines magnetically constitute the magnetic scale, the pitch of the scale can be made minute, the appropriate pattern can be readily obtained and high accuracy can be achieved.

Title: Output voltage detection circuit of voltage inverter
Inventor: TAKAMOTO YASUHISA
IPC: H02M7/5387
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components and to reduce costs, by connecting a series circuit of a diode, a photocoupler, a resistor, and a constant- voltage source in parallel with each switching element of the lower arm of a voltage inverter. SOLUTION: An output voltage detection circuit for detecting on/off of a voltage inverter output voltage for driving an AC electric motor at a variable speed is constituted by connecting a series circuit of a diode 41, a photocoupler 42, a resistor 43, and a constant-voltage source E in series with each switching element 21A of the lower arm of the voltage-type inverter. Then, when an output voltage Vin of the voltage inverter is high, a detection signal Vout from the photocoupler 42 is set to a high level. On the other hand, when the output voltage Vin is low, the Vout is set to a low level, thus detecting on/off of the inverter output voltage only by the diode 41, the photocoupler 42, and the resistor 43 and hence simplifying a circuit.

Patent JP-S5652736-A (JP)
Title: Flash device
Inventor: OKINO TADASHI
IPC: H02M3/335
Filed: 1979-10-08
Abstract: PURPOSE:To achieve the saving of power consumption by series-connecting a Zener diode to the diode connected between the base and emitter of an NPN transistor for oscillation. CONSTITUTION:A Zener diode ZD1 is series-connected to the diode D2 for protecting transistor connected between the base and emitter of an oscillating trnasistor TRQ1. At the time when the TRQ1 shifts from ON to OFF in the process of oscillation action, a counter electromotive voltage is generated in the coil L3 of an oscillating transformer. This counter electromotive voltage is applied to the series circuit of the diodes D2, ZD1, but since the diode D2 is maintained in a non-conducting state by the diode ZD1, the inverse charging to the capacitor C2 is prevented. In this way, the protection of the TRQ1 may be performed and the wasteful power consumption owing to the chraging and discharging of the capacitor C2 may be eliminated.

IPC: G01R25/00
Filed: 1981-08-18
Abstract: PURPOSE:To obtain a phase difference output without DC offset, by setting the operating point so that no current flows to the collectors of differential pair transistors(TR), when no input signal is given to the TRs. CONSTITUTION:Two differential pairs are constituted with TRs Q1, Q2 and Q3, Q4. A current mirror circuit consisting of TRs Q6, Q7 is connected to the common collector connection of the differential pairs. The 1st input signal is applied to each common emitter of the differential pairs after being converted into the signals being in-phase and opposite phase at a transformer T. The 2nd input signal is applied to the base of each differential pair via a differential amplifier consisting of TRs Q8-Q11 and resistors R3-R5. A current flowing to the P-N junction of the TRs Q10, Q11 is made minute through the connection of the resistors R4 and R5, and the operating point is set so that a current flowing to the collectors of the differential pairs is very minute, when the 1st input signal is discontinuous or tentatively missing. Thus, no DC offset is caused to the phase difference output.

Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To save the labor for storage or laying of adders in a hold by supporting a second unit ladder to the tip of a support arm mounted on the inner wall of a hold in such a manner as to be rotatable so that the lower end of a first unit ladder and the upper end of the second unit ladder are pinned to both ends of a connecting member, respectively. SOLUTION: A connecting member 11 has a vertical elliptic hole 12, and a pin 10b is connected so as to be fitted to the elliptic hole. Namely, although the connecting member 11 is rotated around a pin 10a when a second unit ladder 6b is stored, the pin 10b situated in the lower part is moved along a virtual line (b) around a virtual point θ. Since the pin 10b is slid within the elliptic hole 12 at that time, the second unit ladder 6b can be smoothly stored. The elliptic hole 12 and the pin 10b may be formed on the upper end of the second unit ladder 6b and on the connecting member 11 side, as occasion demands, respectively. Further, the pin 10a for connecting the upper end of the connecting member 11 to the lower end of the first unit ladder 6a may be formed into the same structure.
