Title: Hard case for disk cartridge, device and method for manufacturing hard case of disk cartridge
Inventor: ITO TAKESHI
IPC: G11B23/03
Filed: 1990-01-31
Abstract: PURPOSE:To form a pattern rich in a variation by supplying plural thermoplastic materials and preventing them from being completely mixed for coloring while heating and storing them. CONSTITUTION:For example, black thermoplastic material 50a is supplied to a hopper 51 and a hard case in a single color is formed. Next, when the remaining material in the hopper 51 is made a little, a white thermoplastic material 50b is supplied to the hopper 51 without removing, disassembling and cleaning a metal mold 43. The white resin material 50b is non-uniformly mixed with the remaining black resin material 50a in a manifold heater 45 integrated on the fixed side of the metal mold 43. Then, these materials are supplied to a heating cylinder 42, heated, stirred and injected out to the metal mold 43 while maintaining the incomplete mixing state for coloring. Then, the hard case is formed. Thus, without wasting the materials, the case of the cartridge can be obtained with various patterns in the single color.

Abstract: PURPOSE: To make possible correct exposure photographing at all times by performing the exposure and film winding after the automatic exposure by a shutter release second stage switch or the switch parallel with this via counter for delay timer.  
     CONSTITUTION: In the shutter button first stage, a switch S 2  closes by which a transistor Q 1  is turned OFF, FFFF 1  is set and a transistor Q 5  is conducted, thus automatic exposure controlling by a photo detector PD, etc. is accomplished.

IPC: B21B37/00
Filed: 1980-02-26
Abstract: PURPOSE: To forecast the rolling load in high accuracy, by formulating the strain recovery process with modeled numerical formulas in exercising computer control of the rolling mill.  
     CONSTITUTION: The accumultaed strain Δε just before each pass is obtained from the actually measured value of rolling load according to the formula I. In the formula, ε is the logarithmic strain, K mobs  and K mo  are respectively the actually measured deformation-resistance and the standard average deformation-resistance, and a 3  is a constant. Since the values of ε, K mobs  and K mo  can be computed just after causing the deformation, Δε can be found during the rolling work. The strain recovery process at high temperatures is expressed by the formula II. In the formula, (b), a 1 Wa 3  and N 0  are constants, (t) is the time after the deformation, and T k  is the average temperature of the steel sheet. In the rolling work of an ordinary steel sheet or the hot strip rolling work, N 0 =2 is satisfactorily used and the residual strain percentage λ is expressed by the formula III. In the formula, d 0 Wd 2  are constants. Then, the average deformation-resistance k mcal  for the next pass is forecasted by using the formulas I, III, and the rolling load P cal  for the next pass is forecasted by using the formula IV. In the formula, W is the sheet breadth, Q p  is the draft percentage function, ld is the projected length of the contact arc.
