Filed: 1983-04-28
Abstract: PURPOSE:To enable the stable existence of a host microbial cell containing a plasmid having the structural gene of the alkaline phostaphase of Escherichia coli even under the condition to produce a large amount of alkaline phostaphase, by using a specific plasmid vector. CONSTITUTION:The host microbial cell contains tetracycline-resistant gene and trimethoprim-resistant gene as markers and also contains alkaline phostaphase gene. The chromosome DNA of the cell is incised at the PstI site of the restriction enzyme of plasmid vector pTP5-3, and the obtained fraction is combined with pTP5-3 which is incised beforehand with PstI, and bonded together using T4-DNA ligaase. The host bacteria can be survived stably by this process even under the condition to produce a large amount of alkaline phostaphase.

Title: Speed change control device for automatic transmission
Inventor: SUZUKI HIDEO
IPC: F16H61/08
Filed: 1994-03-22
Abstract: PURPOSE:To smoothly change over a speed shift stage by adjusting at least one speed shift so that the speed shift initiating point for a second speed shift falls in a predetermined range from the completing point of a first speed shift. CONSTITUTION:The turn-on time T of a timing adjusting solenoid valve 15 is set to an initial value T0, and whether the kind of speed shift is a shift-down from a fourth speed stage to a second speed stage through three speed stages or not is checked. If the speed shift is the shift-down through by the three speed stages, a detection signal indicating a turbine speed delivered from a turbine sensor 16 is read so as to calculate the elapse time between the completion point of the speed shift from the fourth stage to the third stage and the initiating point of the speed shift from the third stage to the second stage. Further, the turn-on time T of a timing adjusting solenoid valve 15 is changed so that the elapse time falls in a reference time. With this arrangement, it is possible to prevent occurrence of two stage shock due to discontinuous variation in turbine speed, which is uncomfortable for the passenger.

Abstract: PURPOSE: To remarkably reduce the failure such as a decorative part strain or damage at the time of molding a decorative sheet laminate by setting a mold clamping speed to the speed of a predetermined range to thermally compression mold by clamping the mold until both upper and lower molds are brought into contact with a material to be compressed to clamp the mold. CONSTITUTION: A decorating molding is manufactured by setting a mold clamping speed to 0.05 to 2mm/sec to clamp a mold and to thermal compression mold it until both upper and lower molds are brought into contact with a material to be compressed by superposing to dispose a decorative sheet 11 and a thermosetting molding material 12 in a mold, to clamp the mold and to thermally compression mold it. As the molding machine and the mold, a conventionally known press molding machine and a mold or cast mold can be used, but it is important to set the mold clamping speed to a predetermined range from when the movable mold is brought into contact with the material to be compressed to when the mold is completely clamped.  Thus, the failure such as irregular elongation to strain or wrinkle or breakage of the sheet 11 by the abrupt application of the pressure to the sheet 11 or the molding failure of underfill due to delay clamping does not occur.
