Title: Optical length measuring method
Inventor: SUZUKI NOBUYUKI
IPC: G01C3/06
Filed: 1988-01-20
Abstract: PURPOSE:To reduce the measuring error of a spot position, by allowing the long axis of the oval spot striking on an object to be measured to coincide with the direction vertical to the surface containing the respective optical axes of both condensing lenses and setting the length of said long axis to 1.5-3.0mm. CONSTITUTION:The spot SP of laser beam 12 is formed on an object W to be measured and the long axis of said spot SP is allowed to coincide with the direction vertical to the surface S containing the respective optical axes Z1, Z2 of condensing lenses 13, 16. Because of this, the short axis direction of the spot SP becomes the image moving direction on a beam receiving position detector 15 generated by the change of the distance up to the object W to be measured and the center position detection error of the spot SP generated at the boundary part of the hue on the object W to be measured is only generated within the length range of the short axis of the spot SP. Therefore, the center position detection error of the object W to be measured can be reduced in such a state that the noise caused by the surface roughness of the object W to be measured is held to the same degree. Further, by setting the length of the long axis of the spot SP to 1.5-3.0mm, the noise generated by the surface roughness of the object W to be measured can be reduced.

IPC: F01N3/02
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To provide an exhaust gas purifying device capable of reducing cinders of particulates and inhibiting damage to a filter. SOLUTION: An end face heater (end face heating part) 31 for heating the upstream side end face of a filter 2, and an outer periphery heater (outer periphery heating part 32 for heating only the outer-peripheral side face in the upstream part of the filter 2, are provided. The outer periphery heating part 32 heats the upstream side outerperipheral part of the filter 2 in which the quantity of applied heat is relatively running short by the end face heating part 31 alone, and thus the temperature difference between the upstream outer- peripheral part of the filter 2 and the central part in the diametrical direction, is reduced to reduce thermal stress, and thus to prevent cracking (crack) of the filter 2. Further, cinders on the outer-peripheral part of the filter 2 are reduced to prevent the outer-peripheral part from being melted due to the following excessive rise in temperature.

Title: Signal level control circuit
Inventor: YOSHIHISA KOUZOU
IPC: H03G3/10
Filed: 1981-01-28
Abstract: PURPOSE: To eliminate the production of distortion in an output signal of a transistor (TR), by taking TRs for signal pickup as a circuit of Darlington connection and avoiding voltage change between the base and emitter.  
     CONSTITUTION: In a current mirror circuit 4, a Darlington connection circuit is constituted by connecting the emitter of a TRQ 20  to the collector of a Q 30 , the collector of the Q 20  to the base of the Q 30 , and the emitter of the Q 30  to an output terminal 7 respectively. Thus, a voltage V 0  generated across a resistor R 6  of a load 6 is expressed as equation (1). A collector current IOF of the Q 30  is IOF=IB+VF 3 /R d , where IB is the base current of the Q 30 , VF 3  is a base to emitter voltage of the Q 30  and R d  is a resistance value of a resistor R 7 . When a current amplification factor of the Q 30  is sufficiently high, the current IB is  negligible and the current IOF is constant independently of the input current. As a result, the original signal component only is obtained in the output signal shown in equation (I) and the signal component causing distortion can be avoided.

Abstract: PURPOSE:To completely remove metallic compounds, metal oxides, etc., from a metallic organization and to obtain a member from interposing no hole as well and having no surface defect by forming the trace dents of a used male mold on the surface of a base member uniformly without leaving a plane part. CONSTITUTION:Since it is finally necessary to form trace dents unconcentrically and uniformly on the surface of the base member without leaving any plane, a male mold array format drawing a structure superposing the edge parts of adjacent spherical male molds is designed to arrange the male molds. Pressing plates 103A-103C are suddenly pressed to the surface of a cylindrical base member 102 on a holding cylinder 101 by air pressure or hydraulic pressure to form trace dents. Usually, the pressing plates 103A-103C are successively pressed. At the end of the press contact operation of all the pressing plates, the member 102 is moved only by one working plate and the press contact operation is repeated similarly so that the press contact operation in several cycles is executed for one working process.

Abstract: PURPOSE:To attain the assured control of direction by removing an AGC circuit after detecting a receivable channel with an indoor unit for the reception of a satellite broadcasting and at the same time changing the channel to obtain the direction having the highest sensitivity. CONSTITUTION:The signals are received by an outdoor parabolic antenna 1 and supplied to an indoor tuner 11 via a cable 3 after S-U conversion 2. A channel selection circuit 12 produces the local oscillation signals. These signals are mixed by a tuner 11 and supplied to a microcomputer 33 after filtering through a BPF13 for the 2nd intermediate frequency, the level detection 31 and the A/D conversion 32. A character generator 35 and a monitor are connected to the computer 33, and hitherto the highest level of the received channel is displayed together with the level set at that time point. Both the direction and the angle of generation of an antenna 1 are controlled after changing the channel and operating a switch 34 to obtain the best point. Then the control mode is released and changed to a selection mode. In such a way, the antenna direction can be controlled accurately and in a short time.

Title: Thermal protector

Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To increase the contact pressure of a contact for stabilizing the contact and lighten the load for reversely turning a bimetal plate by extending part of a movable plate fixing member and bringing it into contact with the central part of the bimetal plate. SOLUTION: An extending part 6a is formed in a movable plate fixing member 6, and brought into contact with the opposite surface, to a movable plate 3, of a bimetal plate 7. The bimetal plate 7 is slightly deformed and the extending part 6a applies the outside force to the bimetal plate 7. The outside force direction is made the same as the elastic force F of the movable plate 3. The contact pressure between a movable contact 4 and a fixed contact 2 is made large at a temperature lower than the reversely turning temperature of the bimetal 7. When the temperature reaches the reversely turning temperature of the bimetal plate 7, the bimetal plate 7 surely turns reversely from the projecting state upward to the recessed state downward since the outside force from the extending part 6a is applied to the central part of the bimetal plate 7.  When the bimetal plate 7 is reversely turned, a large load is not applied to the bimetal plate 7.
