Title: Coding mode discriminator
Inventor: SHIRAI HIDEYUKI
IPC: H04N1/417
Filed: 1987-09-16
Abstract: PURPOSE:To simplify the control and to quicken the discrimination of a coding mode by executing simultaneously the calculation being a difference between plural sets of bit addresses in the change point on a reference line and a change point on a coded line by means of plural arithmetic circuits and using a discrimination circuit from the calculated output so as to discriminate the coding mode. CONSTITUTION:Plural arithmetic circuits 5, 6 execute the operation of b1-a1, b2-a1 being differences of plural sets of bit addresses with respect to the change point on the reference line and the change point on the coded line simultaneously and the discrimination circuit 7 discriminates the coding mode from the operation output of the plural arithmetic circuits 5, 6. Since the bit address differences of plural sets of change points are obtained at once, the operation time is reduced in comparison with the configuration calculating sequentially the bit address difference of the one set of change point and the time for the operation such as selection of change point and the hold of the change point bit address difference is excluded. Thus, the discrimination of the coding mode is quickened and the control to select the change point or to hold the change point bit address difference is not required to simplify the control.

Title: Back projection device
Inventor: HILLER KLAUS
IPC: G03B21/10
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To make the depth of an entire back projection device as small as possible by allowing a deflection mirror to exist at a position where a minimum angle formed by luminous flux to the surface of a screen while performing deflection is a specified angle which is small. SOLUTION: The deflection mirror 3 is arranged at the angle δwith the projection surface of the screen 2. It is the best to set the upper limit of the angle δ to 45 deg.+β-α/4 in order to make the depth of the device minimum. The angle generally defined as the angle β is 0 deg., but it is possible to set the angle smaller than 10 deg. or 5 deg. instead of 20 deg. being the upper limit. Thus, the depth (t) of the device can be made minimum and simultaneously a projection assembly 1 is prevented from projecting from the screen side of the device. Therefore, the optical path of a light beam is bent by the mirror 3, so that the depth of a housing, that is, the depth of the entire back projection device is made small.

Abstract: PROBLEM TO BE SOLVED: To regenerate the activities of an immobilized lipase capable of providing a liquid crystal raw material or a physiologically active substance by optical resolution or asymmetric synthesis by placing the immobilized lipase having remarkably reduced activities in ester transfer reaction as compared with the initial ones in a polar solvent containing a small amount of water. SOLUTION: Chitosan is dissolved in a 3.5% aqueous solution of acetic acid and the resultant solution is then dropped into a coagulating solution such as a 7% aqueous solution of sodium hydroxide to provide a regenerated granular porous chitosan carrier having 0.1mm average grain diameter. A diglycidyl compound is then added thereto to carry out cross-linking reaction and the resultant product is further reacted with stearoyl chloride to afford a cross-linked granular regenerated porous chitosan carrier. An aqueous solution of a lipase is subsequently added to the carrier to adsorb the lipase on the carrier. The resultant carrier is then washed with water to prepare an immobilized lipase, which is then filled in a column to carry out the ester transfer reaction.  When the activities thereof are reduced to those without exceeding 1/10 of the initial ones, the immobilized lipase is placed in a polar solvent (e.g. acetone) containing 1-5% water to regenerate the enzymic activities. Thereby, the immobilized lipase is regenerated.
