Title: Production of calcium difluoride crystal and treatment of raw material
Inventor: KIMURA KAZUO
IPC: F26B5/04
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a single crystal having a high purity without lowering the degree of vacuum by preliminarily heating the powder of calcium difluoride raw material to desorb impure gases, melting the pretreated raw material in a crucible, remelting the pretreated product in a crucible and subsequently growing the crystal. SOLUTION: The purposes of the treatment for removing the impure gases from the raw material are to obtain the raw material powder having a high quality, the prevention of the staining of a single crystal-producing oven and a preliminarily treating oven and the improvement of production efficiency. Highly pure calcium difluoride powder and scavenger particles are mixed, charged into a crucible, and subsequently gradually heated in an electric oven device in a vacuum state of 10<-4> to 10<-5> Pa within a temperature range of from a lower limit holding temperature of 700 deg.C to an upper limit holding temperature of 1350 deg.C which is the melting point of the calcium difluoride. The scavenger includes lead difluoride, and is preferably added in an amount of 0.1-5 mol.% based on the calcium difluoride.  The preliminary treatment comprises holding the raw material and the scavenger in an oxygen- removed atmosphere at a temperature of 100 deg.C + the decomposition temperature of the scavenger, melting the raw material at 1370-1450 deg.C and subsequently gradually cooling and solidifying the melted raw material to grow the crystal.

Title: Camera
Inventor: KOBAYASHI KAZUYA
IPC: G02B7/36
Filed: 1993-12-27
Abstract: PURPOSE:To realize high-speed and highly precise focusing while maintaining simple configuration by selecting and switching either a range made to limit to arithmetic operation for calculating the DCT coefficient of a frequency domain or the range in which this limitation is not executed. CONSTITUTION:AF control based on an obtained transformation coefficient is executed by using a feature that a coefficient value is small both in the case that a lens position is at approximately infinite distance and the in the case that it is at the closest distance, and the coefficient value shows a peak at a focusing position. The AF control is executed in this way by using an increasing and decreasing variation of the transformation coefficient value, but if the area of the coefficient to be used for the AF control is fixed, and the AC transformation coefficient of only a part to be used is determined by DCT (discrete cosine transformation) operation, focusing speed is improved. For instance, if the transformation coefficient of only a hatched part area (to show frequency domain) is used for the AF control, the DCT operation can be finished only with that of the hatched part. Namely, in this case, the range of either the DCT operation of an AF area part or the DCT operation of compression recording can be switched.

Title: Carrier for developer
Inventor: KOMATA HIROTSUGU
IPC: G03G9/113
Filed: 1988-12-28
Abstract: PURPOSE:To form sharp images having a high density over a long period of time without generating carrier attraction by using a magnetic resin carrier dispersed with conductive magnetic iron carbide having specific saturation magnetization in an insulating binder resin. CONSTITUTION:The conductive magnetic iron carbide having the high magnetization force of >=90emu/g saturation magnetization is used as the magnetic material to be dispersed and incorporated into the binder resin. This conductive magnetic iron carbide has the relatively high saturation magnetization and the excellent dispersibility and bindability in the resin and is able to increase the magnetic flux density without degrading the durability of the carrier merely by incorporating a small ratio thereof into the resin. The images having the high density and high resolution are thus formed without generating the carrier attraction and without fogging over a long period of time.

Further, liquid crystal is injected in isotropic liquid phase and then while the AC electric field of low frequency is applied, natural cooling to the ferroelectric smectic phase is carried out to form an excellent monodomain. Consequently, the extent of the formation of a monodomain which causes the lowering in contrast is improved greatly and the need for the annealing process is eliminated.

Abstract: PURPOSE:To execute an image output in a color being faithful to input image data without impairing gradation. CONSTITUTION:Color image data is fetched from an image memory, and a counter CN1 is subjected to increment. Subsequently, whether the inputted color image data is outside a color reproducing range of an output system or not is decided.

It is executed wit regard to all the image data, and when it is finished with regard to all, a ratio of two counters CN1, CN2 and a threshold N are compared. When the ratio is below the threshold N, and only when the color image data is outside the color reproducing range of the output system, a first compression processing for compressing the data to the outside periphery of a reproducing range of the nearest output system is executed, and when the ratio exceeds the threshold, a second compression processing for compressing the data by using a function for compressing it linearly is instructed from a relation of a color reproducing range of an input system and the color reproducing range of the output system.
