A ceramics sample having an appropriate size is stuck to the sample holder, and then, the micro probes 2 are visually moved near the surface of the sample. Thereafter, the SEM is vacuum-exhausted, thus generating an electron beam. In work for confirming the sample and the tip of the micro probe 2, PZT ceramic 3 (driving element of the micro probe) is driven to finely adjust the micro probe 2 in an arbitrary position after determination of an observed region. Consequently, it is possible to grasp electric properties of the arbitrary fine region in the sample.

Title: Thermal recorder
Inventor: IINO KINZOU
IPC: B41J2/36
Filed: 1982-02-09
Abstract: PURPOSE:To retain a better quality of recording by a method wherein a square wave pulse is generated as a specific function of the X-direction relative speed Vx of a thermal pen and a thermal recording paper and a resulting voltage as a function of Vy is applied intermittently to the thermal pen with a chopper circuit. CONSTITUTION:An input signal e1 is entered as analog voltage corresponding to the position of a thermal pen in the Y-axis direction while a voltage e0 is outputted from a position detector 6 corresponding to the position of controlling a thermal pen 12 for the feed back control thereof via an error detector 2, an amplifier 3, a servo amplifier 4 and a servo motor 5. Therefore, the output of a differentiation circuit 7 is so proportional to the Y-direction relative speed Vy that current proportional to the output f(Vy) of an arithmetic amplifier 8 is fed to the thermal pen 12 through a transistor 9. On the other hand, paper is fed at a speed Vx via a speed selection 15 from a paper feed motor 14 while a pulse width modulation circuit 16 outputs a square wave pulse with the width related to Vx to cut off the current to the thermal pen 12 with a transistor 10. Therefore, the heating power of the thermal pen can be controlled within a variation range of Vx and Vy to retain a better quality of the recording.

Filed: 1981-02-10
Abstract: PURPOSE:To prevent the damage of a switch depressing member, by forming the door switch depressing member as a body independent of a door main body and detaching this member from the door main body when an excessive force is applied to it. CONSTITUTION:When a door 1 is closed, a switch depressing part 23 in an arc part of a switch depressing member 2 depresses an operating arm 41 of a control switch 4 provided in a control device 3 to turn on the switch 4. When the door 1 is opened, the switch 4 is turned off because the switch depressing part 23 does not depress the operating arm 41. When a shock is applied to the switch depressing member 2 under this state, a projection 11 is detached from a fitting hole 24 of the depressing member 2 by the elasticity of the depressing member 2, and the cover main body 1 is detached from the control device 3. Thus, the damage of the switch depressing member 2 due to shock is prevented.

IPC: H02J7/02
Filed: 1994-02-16
Abstract: PURPOSE:To provide a controller with charging function suitable for an electric vehicle in which safety is enhanced economically by preventing current from flowing to an unnecessary part. CONSTITUTION:At the time of running, a motor relay 7 is turned ON and a motor 3 is fed with power from a battery 1 under control of a controller 2. Since a charging relay 8 is turned OFF, power is not fed from the battery 1 to a transformer 4. At the time of charging, the charging relay 8 is turned ON, and the controller 2 is fed with power from an external AC power supply through a connector 5 and a transformer 4. The controller 2 also converts the AC power supply into DC power for charging the battery 1 while controlling the current. Since the motor relay 7 is turned OFF, the motor 3 is not fed with the AC power supply. Reverse interlock operation between the motor relay 7 and the charging relay 8 is ensured through the function of a mutual inhibit circuit cross-connected with an exciting coil at an auxiliary contact.

A current of exhaust gas mixed with ammonia is passed through a porous plate 13 to fluidize granular particles containing titanium oxide so as to perform exchange of heat with a fluid to be heated, such as water, passed through a heat exchanger tube 3. On the other hand, NOx in the exhaust gas reacts with the ammonia to form harmless N2 gas by catalytic reduction in the presence of a granular catalyzer containing titanium oxide, and then the exhaust gas passes through a porous plate 15 underlying the upper fluidized bed 2 and fluidizes the alumina or silica sand so as to perform exchange of heat, by means of a heat exchanger tube 4, with the fluid heated by passage through the lower fluidized bed 1. After passage through the two fluidize beds, the exhaust gas and the heated fluid both are led out of the fluidizing apparatus.
