Abstract: The invention comprises steroids of the general formulae <FORM:0931296/IV(a)/1> wherein R represents hydrogen or an acyl group, X represents bromine or iodine and R1 represents an acyl group, and the preparation of the steroids of the first general formula by treating steroids of the general formula <FORM:0931296/IV(a)/2> wherein R has the above significance and Q represents the divalent radical of a nitrogenous ketone-protecting reagent such as hydroxylamine, semicarbazide, hydrazine or a substituted hydrazine with a solution of a strong mineral acid, the preparation of the steroid compounds of the second general formula above by treating the steroid compounds of the first general formula above with bromine to form the 21-bromo compound and then with an alkali metal iodide to form the 21-iodo compound, and the preparation of the steroid compounds of the third general formula above by treating the steroid compounds of the second general formula above with an alkali metal acylate.  The above processes may be modified in that the steroids of the second general formula above are prepared by a process claimed in Specification 931,295.

Title: Semiconductor integrated circuit and its accelerated degradation test method
Inventor: TOUHO MITSUHIRO
IPC: G01R31/30
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To give a more proper source voltage for accelerated degradation test according to the scattering in production process and the shift from design parameters. SOLUTION: A semiconductor integrated circuit is provided with a step-down circuit for accelerated degradation test 40 and the circuit 40 divides the external source voltage VDD with resistors 43 and 44 and controls the gate voltage of a load pMOS transistor 41 for step-down so that the divided voltage Vr becomes an internal source voltage Vdd with a comparison circuit 42.  By adjusting the divided voltage Vr in accordance with the scattering in the production process and the shift from design parameters, the internal source voltage Vdd for the accelerated degradation test is lowered lower than the standard value when the gate length of the MOS transistor in the semiconductor integrated circuit is shorter than the design value, and the internal source voltage Vdd for the accelerated degradation test is elevated higher than the standard value when the gate length is longer than the design value. By this, the excess and lack of stress given to the semiconductor integrated circuit is automatically reduced.
Patent JP-H03207685-A (JP)
Title: Recording apparatus
Inventor: TAKAHASHI HIROYUKI
IPC: B41J2/515
Filed: 1990-01-09
Abstract: PURPOSE:To prevent relative positional shift in a main scanning direction by allowing the whole of recording data to correspond to the recording element within the range set corresponding to the sheet of the recording position in a medium to be recorded or the relation with the recording position due to other recording head. CONSTITUTION:A resist clutch 104 CL transmits rotation and a pulse signal RT is turned ON with the start of the supply of recording paper. A counter 502C starts the counting of a clock VCK corresponding to the fall of the signal RT and outputs a count-up signal after the elapse of a predetermined time. The predetermined time shows the time required before the recording paper 201 reaches the position opposed to the emitting orifice of a recording head 106C and the recording due to the recording head 106C becomes possible from the point of time when the count-up signal of the counter 502C is outputted. The range of a sub-scanning direction becoming possible in recording is determined by the 'ON' period of the signal VEY(C) outputted from an F/F 503C and the length of the 'ON' period is prescribed by starting the counting of the clock VCK corresponding to the output from the counter 502C through the F/F 503C by the counter 504C to count the clock VCK for the predetermined time.

Title: Compact disk driving device
Inventor: UIRUSON WAI SHIN REUN
IPC: G11B25/04
Filed: 1995-01-09
Abstract: PURPOSE: To simplify a motion mechanism by letting a spring act a relatively large elastic force to a tray when the tray slides between a closed position and an intermediate position. CONSTITUTION: A reproducing mechanism 14 operates only when a tray 13 moves between an intermediate position and a closed position. A spring 30 works solely for the period, adding a force to a force applied from a spring 16 so that the tray 13 slides outward via a slot 12. The added force helps the tray 13 (and a compact disk put in the tray) to overcome an inertia to be quickly discharged. In an opposite direction, the added force exerts a buffering effect or damping effect immediately before the tray 13 is pressed back to the closed position, decreasing the danger of a sudden motion or damage.
