Title: Supply controller for abrasive in method of abrasive jet cutting construction
Inventor: SASAKI KOJI
IPC: B26F3/00
Filed: 1987-08-19
Abstract: PURPOSE: To hold the quantity of abrasive fed to a nozzle at a prescribed fixed value by controlling the feed quantity of the abrasive from a feeder based on an electric signal from a speed sensor which detects the feed quantity of the abrasive fed from the feeder to the nozzle. CONSTITUTION: An abrasive moving speed is detected by a speed sensor 16 and the feed quantity of the abrasive which fallen from a feeder 15 to be sent to a nozzle 7 is thus sent to an electric controller 18 as an electric signal. The turning-on/off and the rotating speed of the feeder 15 are controlled based on the difference between the feed quantity measurement value and the set value in the electric controller 18. The feed quantity of the abrasive fed from the feeder 15 to the nozzle 7 is thus held at a desired fixed value at all times. In this case, when no abrasive is sent thereto because of the closure and breakage of a transport pipe 12b, it is detected by the speed measurement value by the speed sensor 16 dropped to zero so that the progress of the cutting work by the abrasive is stopped and the generation of an uncut position is prevented before happening.

Title: Elastic body roll
Inventor: YAMAZAKI HIROTAKA
IPC: B65H27/00
Filed: 1994-08-08
Abstract: PURPOSE:To enhance the function of wear resistance in view of a structure by forming many wear attenuation grooves on the external surface of a roller coming in contact with a sheet-shaped product. CONSTITUTION:Many grooves 2 are formed on the rigid body contact surface 3 of an elastic body roll 1 repeatedly in frictional contact with a rigid body (including paper), and the width of each groove 2 is taken at W with the depth at (t), while a gap between the grooves 2 is taken at L. When the width W is too small, both sides of the grooves 2 come in contact with each other, due to an external force, leading to the loss of the effectiveness of the grooves 2. On the other hand, when the width W is too large, not only a friction factor is reduced, but also an abnormal vibration is induced or an abnormal fracture occurs, due to the reduction of a contact area with the rigid body. Thus, the width W is taken as 0.1mm<=W<=2.0mm. Also, the effect of wear reduction increases, according to an increase in the depth (t), but the break of the roll 1 is liable to be caused. Thus, the depth (t) is taken as 0.05mm<=(t)<=2.0mm. Furthermore, when the gap L is too small, the surface lateral rigidity of the body 1 is reduced, while too large a value of the gap L leads to the loss of the effectiveness of the grooves 2. Thus, the relationships of 1.0<=L/W<=20 and 1<=L/(t)<=200 are established.

Title: Electronic camera for still picture
Inventor: HORIO MOTOHIKO
IPC: G03B9/02
Filed: 1986-09-02
Abstract: PURPOSE:To eliminate the indeterminate elements for a diaphragm value by limiting the lower limit value of diaphragming in case still mode is commanded. CONSTITUTION:In case the still mode is selected by means of a still/movie switching means, the part of diaphragm range near the minimum value is regulated not to be used. More concretely, an arithmetic/exposure controller 32 limits the number of pulses supplied to a stepping motor drive circuit 36 in order that the diaphragm is not narrowed beyond a specified diaphragm value. As a result, in the still-mode photographing mode, a more correct control of exposure can be executed because the part of diaphragm range near the minimum value that is apt to make the diaphragm value inderminate can be avoided to be used.
