The present invention provides a packing sheet and PTP packing body, which do not include halogen materials such as chlorine and fluorine and have high water vapor barrier property. The packing sheet of the present invention includes at least a high-density polyethylene resin (A), petroleum resin (B), and amorphous polyolefin resin (C). Also, it is preferable that the weight blending ratio ((A+B)/C) of the total weight of the high-density polyethylene (A) and the petroleum resin (B) to the weight of the amorphous polyolefin (C) be 50/50 or more and 90/10 or less.

An optical device includes: a light guide plate receiving, for each of N types of wavelength bands, a plurality of parallel light beams with different incident angles each corresponding to view angles, and guiding the received parallel light beams; a first and a second volume hologram gratings of reflection type having a diffraction configuration which includes N types of interference fringes each corresponding to the N types of wavelength bands, and diffracting/reflecting the parallel light beams. The optical device satisfies for each wavelength band, a relationship of ‘P>L’, where ‘L’ represents a central diffraction wavelength in the first and second volume hologram gratings, defined for a parallel light beam corresponding to a central view angle, and ‘P’ represents a peak wavelength of the parallel light beams.

The present invention provides a memory control device and a semiconductor processing apparatus which can be flexibly made adapted to a plurality of kinds of semiconductor memories. An SDRAM controller has: a register unit to which a command to be issued and a minimum interval (wait time) between issue of the command and issue of the next command are written by a CPU; and a command issuing unit that stops issue of the next command until the minimum interval written in the register elapses since issue of the command written in the register. Therefore, by changing software for the CPU, the SDRAM controller can be flexibly adapted to a plurality of kinds of SDRAMs.

To improve corrosion resistance in wet environments, for a martensitic cast steel material obtained at a predetermined composition ratio and martensitic steel casting products, and to provide a martensitic cast steel material that is appropriate for various types of molds and dies, mechanical parts, etc., and a manufacturing method for martensitic steel casting products.Nickel, Ni, of 5 to 10 mass %, silicon, Si, of 0.5 to 5 mass %, manganese, Mn, of 0.01 to 1 mass %, carbon, C, of 0.2 to 2 mass % and a remaining part consisting of iron, Fe, and incidental impurities are employed, and further chromium, Cr, of 1 to 10 mass % is added to obtain a martensitic cast steel material for which a martensitic transformation finish temperature (Mf point) is below freezing. Further, a cast steel material that contains vanadium V of 0.1 to 5 mass % in addition to the above elements of the material is also obtained. For these cast steel materials, since martensitic transformation occurs merely by performing a sub-zero treatment, the tempering process can be comparatively easily performed, and machining in a desired shape is easily performed.

A printer that can reduce a manufacturing cost is obtained. The printer according to the invention includes a casing as a base member, a movable member and a spring. The movable member is movable with respect to the casing. The spring is located between the casing and the movable member. The casing is provided at a position opposed to the lower end of the spring with a projected portion (circular convex portion) arranged to pinch the lower end of the spring. The position of the spring with respect to the casing is fixed by the state in which the lower end of the spring is arranged radially inside the circular convex portion. The movable member is provided at a position opposed to the upper end remote from the lower end of the spring with a fixing portion (projected fixing portion) for fixing the upper end of the spring.
