Title: Coating method for metallic member
Inventor: SUZUKI MOTOAKI
IPC: C23C4/10
Filed: 1986-11-10
Abstract: PURPOSE:To easily form a secure coating having high adhesive power by heating the surface of a metallic member in a low-pressure atmosphere just before melting by arc heating and spraying a hyper-fine powder material of ceramics, etc., thereto at a high velocity by an inert gas. CONSTITUTION:An arc is splashed from an arc bar 2 provided perpendicularly to the surface of a metallic sheet 1 in the low-pressure atmosphere of about 10<-1>Torr to heat the surface up to the state just before melting. The hyper-fine powder 4 of <=1mum grain size consisting of ceramics of metallic material transported by the inert gas is sprayed from a hyper-fine powder injection nozzle 3 at the high velocity to the surface heated to the half-melted state. The hyper-fine powder 4 having good reactivity is thereby bombarded with high bombardment energy to the surface of the sheet 1 and is stuck with the high adhesive power thereto without generating residual stresses in the sheet 1, by which the secure coating layer 5 is formed.

Title: Feed controlling method of turning shaft in machine tool
Inventor: MIZOGUCHI KIYOHISA
IPC: B23Q15/10
Filed: 1984-12-17
Abstract: PURPOSE:To make undue variations so as not to be produced in a cutting speed, by varying a feed angular velocity in a turning shaft according to a distance of a turning tool from the turning center of a work, and thereby keeping a tangential velocity of the turning tool, during operation, constant all the time. CONSTITUTION:There is provided with a tool position detecting device such as a transducer 17, a tool feed control part 5, etc., detecting the existing position LN of a turning tool 15, and on the basis of the existing position LN of the turning tool 15 to be outputted out of the said detecting device, a distance (r) ranging from a Z-axis or the turning center of a work 16 to the turning tool 15 is found. According to this distance (r) and the inputted tangential velocity FVC, a turning shaft of a spindle 12 is rotated at such an angular velocity FVtheta as making the tangential velocity in time of machining the work 16 by the said turning tool 15 constant. Therefore, machining of the work 16 by the turning tool 15 is controlled so as to keep the tangential velocity constant all the time even if the distance (r) varies, so that undue variations in a cutting speed will no longer happen there, thus the work 16 is machinable in good conditions.

Title: Method and device for detecting developer residual quantity and image forming device using them
Inventor: KISHIMOTO HIROYUKI
IPC: G03G15/08
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To precisely judge the residual quantity of developer by canceling the effect of change and to evade the erroneous detection thereof by changing a judgement reference according to an image forming condition such as an operation time or a developing bias value and/or image forming environment such as temperature or humidity when a characteristic value corresponding to the residual quantity of the developer is detected and compared with the reference for judgement. SOLUTION: The residual quantity of the developer 1 is judged by detecting the prescribed characteristic value corresponding to the residual quantity of the developer 1 in a developer container 6, for example, the output voltage of a photodetector 12 and comparing the detected result, for example, the detecting time and the number of continuous detecting time of a pulse P shown by a detected voltage value with the judgement reference, for example, the pulse detecting time being >=100 msec and the number of continuous detecting time that the pulse P is continuously detected three times. Then, the judgement reference is changed according to the image forming conditions and/or the image forming environment related on the forming action of a latent image and compared with the detected result.  Thus, even when the detected result is changed according to an endurance time, the residual quantity is precisely judged by canceling the effect of the change.

Title: Show case
Inventor: UCHIUMI HIROYUKI
IPC: F25D19/00
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a show case with a good maintenance and good cooling efficiency in a machine chamber. SOLUTION: A front base table 4 is disposed in a machine chamber 4, which table is being taken out before and behind, and a condenser 19 and a condenser fan 21 are disposed on the base table 42, and further refrigerant pipings 53, 54 are connected with the condenser 19 and are formed into an expandable configuration in the direction where the base table can be taken out. Accordingly, the front base table 42 can be taken out while keeping connection between the refrigerant pipings 53 and 54 unchanged. Thus, maintenance workability for instruments disposed on the front base table 42 is improved. Further, since the refrigerant pipings 53, 54 are connected with the condenser 19, there is eliminated the need of covering the pipings with a heat insulating material, etc., so that an occupation volume in the machine chamber 4 is reduced even when the heat insulating material is wound into a coil configuration. Therefore, the ventilation of the machine chamber 4 becomes satisfactory so that cooling efficiency is improved.

Abstract: PURPOSE:To shorten data transfer time as well as correcting image drawing time by a method wherein variable dimensional beam shot (vector scanning) system is adopted for normal image drawing process while either variable dimensional beam or one line luster scanning system is adopted for ON.OFF reversing image drawing process to correct proximity effect. CONSTITUTION:Beams are formed after the dimension of pattern data 1-4 to draw images with beams shifting the positions 1-4 thereof by vector scan ning system. The pattern 4 with lateral dimension thereof larger than the maxi mum variable dimension may be divided into two parts. Assuming beam length to be 111 required for normal image drawing process with objective lens current fluctuated by specified value, the beams may be enlarged by out of focus 112.
