Title: Die structure for relay optical system frame
Inventor: UENO TAKUYA
IPC: G03B13/02
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To equalize the thickness of a molded frame to the ends thereof by forming blanking dies in such a manner that the parts corresponding to the peripheral surfaces of mirror mounting parts can be blanked along the optical axis direction. SOLUTION: Sliding cores 39a, 39b for forming a mirror mounting window are so formed as to be blanked along the optical axis direction of first to third lenses 18 to 20 which are non-perpendicular to the respective reflection surfaces of second and third mirrors 16, 17 and are relay lens groups. Next, the sliding cores 39a, 39b are so formed as to be blanked straight along the optical axis direction. As a result, the peripheral surfaces of the mirror mounting windows 33, 34 of a finder holder 13 are so formed that the interference of the wall surfaces with the outermost optical paths is eliminated even if the thickness to the ends is made uniform. In addition, the thickness of the finder holder is reduced and the size thereof is reduced.

Title: Display device with memory function
Inventor: FUJITA SHINGO
IPC: G02F1/1343
Filed: 1988-01-25
Abstract: PURPOSE:To obtain a display device having a memory function by laminating a substrate to form plural closed circuits composed of a superconducting material and a displaying element to generate a magnetic field optical change. CONSTITUTION:In a liquid crystal layer 7, a liquid crystal molecule is arranged in parallel to substrates 3 and 4 surface and formed while a closed circuit 8 composed of a superconducting material formed on the substrate 4 is plurally mutually insulated. When a magnetic field is impressed in a direction vertical to a substrate surface, the liquid crystal molecule changes the arrangement in parallel to the magnetic field direction and the closed circuit 8 composed of the superconducting material wholly catches the magnetic field. Two laser beams execute the two-dimensional scanning and the superconducting material of the prescribed place of the substrate is transferred to a normal conductance condition. Consequently, the caught magnetic field is vanished and the liquid crystal molecule of the part is transferred to the arrangement in parallel to a substrate surface. Thus, the presence and absence of the magnetic field can be obtained at the prescribed place of the substrate and a prescribed displaying can be executed.

Filed: 1980-02-07
Abstract: PURPOSE:To make it possible to measure the coating amount with high precision in on-line mode by dividing a coating material, sticking to an application roll, into two--the part in contact with a substrate and the other-- and by measuring the weights of them by collecting them for a long time with doctors 13 and 14. CONSTITUTION:Doctor 15 is provided where application roll 11 of a natural roll coater comes into contact with substrate (a), and doctors 13 and 14 are also provided where it never contacts with it. Application weight W per unit area of substrate can be found by the formula, where the width of each doctor is denoted as B, running speed of substrate (a) as V, and collection times and application weights of the parts which contact and do not contact with substrate (a) as T1 and T2, and w1 and w2 respectively. In this constitution, the coating material of the 1st rotation which may cause an error is removed first by doctor 13 and the coating material is collected by doctors 14 and 15 to measure the weight respectively, thereby finding the coating amount from the said formula. Thus, the measurement can be taken with precision in on-line mode.

IPC: F26B17/14
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of the measured moisture value averaging processing of a moisture measuring instrument when the instrument measures the moisture of grains while the grains are fed. SOLUTION: Sectional feeding amount-predicting means which predict the feeding amounts of grains at every grain section having nearly equal moisture values are constituted by installing moisture meters to the middle of a transferring route along which the grains are fed to a storage tank and a calculating means which calculates the average moisture value of the grains by weighting the detected moisture values of the moisture meters by using the feeding amount ratio of each section to the total feeding amount is constituted.

Abstract: PURPOSE:To stop the rotation of a tap in abnormal torque generation during forward rotation and to certainly reverse the holder for drawing a cutter out of a threaded hole by so forming the clutch ball hold hole of an inverted shaft as to be inclined to the direction opposite to the forward direction of a cutter rotation as the hole is extended to the side of a clutch groove. CONSTITUTION:An inverted shaft 4 is fitted to the inner periphery of a drive ring 6 rotating in a body with a tool holder body transferring the torque from the drive ring 6 through a clutch ball 8 or the like. The hole 16 for holding the clutch ball 8 is so formed as to incline to the direction of the forward rotation A of the shaft as the hole is extended to the inner side in the radial direction and to the direction of the reverse rotation B of the shaft as extended to the side of the drive ring 6. Although the transfer torque necessary while rotating and advancing the holder for screw thread cutting is secured by adjusting a clutch spring 9 to set a clutch at a maximum transfer torque, being overloaded, the drive ring 6 is twisted in the direction of A to the shaft 4 to push the ball 8 to the inside along the ball hold hole 16 disengaging the clutch. While in reversing for drawing a cutter out of the threaded hole, the clutch is engaged.

Title: Travel recognition system of wiring
Inventor: HODOZUKA MASAO
IPC: G06F17/50
Filed: 1985-01-29
Abstract: PURPOSE:To reduce designing time by referring with data in a table including pseudo points installed in the wiring pattern when discriminating the installing possibility of a new wiring pattern. CONSTITUTION:It is assumed that the installing possibility of a wiring pattern 8-4 connecting a hole 3 or a small Via6 positioned to the left of a main lattice 2-1 and a hole 3 or Via6 positioned to the right of a main lattice 2-3 is discriminated. In the main lattice 2-1, it is discriminated that further three wiring patterns 8 can be installed since the holes 3-1, 3-4 exist. Then the discrimination point is shifted to a sub-lattice 5-1 to judge if the pattern 8 can be installed. In such a case, for providing the pattern 8 at the upper side of the small Via6-1, it is necessary to make an intersection with the divided wiring pattern 8-3 connecting the hole 3 and the pseudo point 9-2. Thus it is discriminated that it is impossible to mount a new pattern 8 between the lattices 2-1 and 5-1. According to this system, it becomes unnecessary to refer with the both end data so that the designing time is reduced.

Title: Off-track state detector for optical reproducing head
Inventor: MUKAI TOSHIHARU
IPC: G11B7/09
Filed: 1986-01-27
Abstract: PURPOSE:To obtain an inexpensive and stable off-track state detector which is easily made small-sized and is independent of the rotation period of a disk, by detecting the damage of the disk by an asynchronous logic circuit which is independent of the rotation period of the disk and does not require passive parts such as a capacitor. CONSTITUTION:A pulse converting means 103 and a state transition discriminating means 104 consist of asynchronous logics, and time elements which control their logical states are only gate delay times of a NOR circuit, a buffer, an inverter, etc., constituting them and are independent of the period of an input signal (a). Consequently, an off-track position of a reproducing head 2 is detected faithfully independently of the rotation period of the disk. Since the detector consists of an asynchronous logic circuit, passive parts such as a capacitor are not required to make the detector inexpensive and small-sized easily.
