Filed: 1984-02-22
Abstract: PURPOSE:To output laser beams, which have excellent symmetry and in which there is no axial displacement, by providing an axial displacement detecting means for laser beams while furnishing an angle correcting means for a mirror. CONSTITUTION:Axial displacement sensors 70 detecting the degree of axial displacement from a set optical axis of the optical axis of laser beams are disposed on the circumference of a circle formed in the foot of laser beams in the vicinity of the front of an aperture 7 and in the vicinity of the front of a total reflecting mirror 6. The axial displacement sensor 70 is constituted by a holder 72 and light-receiving elements 71. The axial displacement of laser beams in the X direction can be detected by comparing outputs X1, X2 from the light-receiving elements 71 and that in the Y direction by comparing Y1 and Y2. The angles of a partial reflecting mirror 5 and the total reflecting mirror 6 fitted are corrected so that the optical axis of laser beams 9 is positioned on the set optical axis on the basis of signals from the axial displacement sensors 70.

Title: Metallic mold for wax pattern and manufacture of wax pattern using the same
Inventor: ANZAI KO
IPC: B29C33/52
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To enable the reusing of a wax core and to reduce the manufacturing cost and manufacturing manhour by forming a recessed part for reducing the thickness of the wax core near an undercut part at the back surface side of the soft material-made wax core forming a part of the cavity surface containing an undercut part and fitting a hard material-made insert member so as to be possible to insert/pull out. SOLUTION: The wax is filled into a cavity 10 from a wax pouring hole 5 to form a wax pattern 2 having an undercut part 3. At this time, the filling pressure is loaded onto the inner wall surface of the cavity 10 but the wax core 1 is not largely deformed because the recessed part 1b is supported with an insert member 8, and further, a soft material is used, but the deformation of the thick portion can be disregarded because the soft material is of comparatively thin thickness. After the wax pattern 2 is cooled and solidified, the insert member 8 is pulled out to the right side. Successively, when a movable side pattern plate 7 is shifted to the right side, simultaneously, the wax core 1 is shifted and separated from the wax pattern 2 while deforming without developing any damaging.

Filed: 1978-03-24
Abstract: PURPOSE:To hold an assured current mirror ratio and at the same time to ensure the operation with the low voltage by connecting the resistance between the connections of the base of the input-side transistor Tr, the collector of the input-side transistor Tr and the base of the output-side Tr respectively and then selecting the resistance to a proper value. CONSTITUTION:Resistance R is connected between the connections of the collector of input-side transistor Tr1, the base of output-side Tr2 and the base of Tr1 respectively. In such constitution, the relation of I1 = I2 is obtained from equation (1) with the current mirror ration of ''1''. In other words, the value of R is selected so that the current of 0.9mA may be the sum of collector current i11 of Tr1, base current i1 and base current i2 of Tr2, thus obtaining the current mirror ratio of ''1''. Thus, the value of R is selected so as to satisfy equation (1) in consideration of the value of the base current of Tr1 and Tr2, accordingly holding the fixed current mirror ratio assuredly and then securing the operation. Furthermore, the driving can be secured with the low voltage since just one unit of Tr is connected at the input side.
