A current is made to flow from the drive circuit 7 to the heating resistor 1 and it is corrected by the temperature-sensitive resistor 5 so that a difference between the temperature of the heating resistor 1 and that of intake air be a prescribed one. In other words, a large current is made to flow when a flow rate is high, while a small current is made to flow when the flow rate is low. A current value thereof is measured and the flow rate of the air is detected therefrom. On the occasion, the support pin 4 formed of a conductive layer is divided into two layers, an outside layer and an inside layer, by an intermediate layer formed of an insulator, and the heating resistor 1 or the temperature-sensitive resistor 5 is welded to either of the two layers. A module including the support part 3 is formed to be symmetric laterally. Thereby general-purpose properties for fitting is widened and the kinds of products are reduced.

IPC: G01B15/04
Filed: 1984-12-05
Abstract: PURPOSE:To speed up the measurement of a ray width by storing a digital signal subjected to A/D conversion as well in a converter for A/D conversion of a secondary electron signal. CONSTITUTION:An arithmetic circuit 5a can convert sequentially data to analog to digital data according to the program stored in a storage device 5b and feed the digital data to a storage device 6a and a deflection signal generator 6c. More specifically the circuit 5a transmits the coordinate 7l at the start point of a scanning line, the length 7m of the scanning line and the repeating time 7n of scanning as initial set information to the generator 6c and transmits the length 8m of the scanning line and the times 8n of the scanning as initial set information to the A/D conversion and storage device 6a in the stage of starting scanning. The data transfer by the arithmetic circuit is only required at the first time if such constitution is adopted. The arithmetic circuit does not intervene the operation at all after the scanning of the beam is started and therefore the conversion and addition of the signal data are speeded up.

Title: Drill bit
Inventor: BIRK RUDI
IPC: B23B51/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To make a drill bit suitable for boring holes in various kinds of materials, particularly, reinforced concrete, and improve the service life and durability by forming a stepped part arranged on the respective sides of the central axis of the drill bit formed on a tip in the shape of cutting a workpiece according to rotation around the axis. SOLUTION: At using time, when boring is started, an outside part 13 of a drill bit tip acts so as to cut a residual part of a hole. However, in a step part of the outside part 13 of the drill bit tip, the outside part 13 is actuated as a chisel along the whole of a cutting edge 21 in a limited range. A boring process of these two actions makes an accurate hole in a workpiece. A directional change in the cutting edge 21 by a stepped structure, that is, interruption of the cutting edge 21 brings about reduced cutting force. Metallic sections from a bar caused by an interrupted characteristic of the cutting edge 21 are all formed as broken pieces smaller than a length of chips, and these broken pieces are easily transferred so as to separate along a web of spiral steel.

Title: Developer control system in electrophotographic device
Inventor: KARASAWA KAZUNORI
IPC: G03G21/00
Filed: 1989-10-03
Abstract: PURPOSE:To prevent an abnormal image in terms of density drop and trouble from toner splashing by displaying abnormality if the comparison of a previously detected density with a currently detected density, both of which are detected by a sensor detecting density based on the density of the same reference image, indicates the difference between the two densities is against the correction of reference output and exceeds a prescribed one and inhibiting the action of an electrophotographic device. CONSTITUTION:The device is provided with an F sensor 9 which employs a two- component developer and detects the concentration of toner in a developer when the device starts up. The concentration of the toner is controlled so that an output detected by the sensor agrees with the reference output. When the device is inoperable, the reference image is formed on a photosensitive body 1, and the reference output is adjusted according to the reference image density detected by a P sensor 10, thereby adjusting the toner concentration. At this time, the previous density is compared with the current one, both of which are detected by the P sensor using the same reference image, and abnormality is displayed if the difference between the two densities is against the correction of the reference output and exceeds the prescribed one. Ultimately, the operation of the device is stopped. Thus, a drop in image density and troubles mainly from toner splashing can be prevented.
