Title: Method of purifying carnitine
Inventor: FUKUI SAKUZO
IPC: C07C227/00
Filed: 1984-09-06
Abstract: PURPOSE:To purify carnitine in high purity, by treating an aqueous solution of carnitine containing crotonobetaine as an impurity with an acidic sulfite, adsorbing carnitine on a cation exchange resin, and recovering carnitine. CONSTITUTION:An aqueous solution of carnitine containing crotonobetaine as an impurity is treated with an acidic sulfite (e.g., acidic sodium sulfate), carnitine is adsorbed on a cation exchange resin (e.g., strongly acidic cation exchange resin), and recovered. Before the aqueous solution is treated with the acidic sulfite, the aqueous solution of carnitine is adjusted to 7-9pH, and preferably >=2mol sulfite based on 1mol crotonobetaine is added to the aqueous solution at 40-70 deg.C. The treatment of crotonobetaine with theacidic sulfite provides an adduct which is not adsorbed on the cation exchange resin at all, so it is efficietly separated from carnitine which is adsorbed on the cation exchange resin.

Title: Film unit with lens
Inventor: ISHIDA MASARU
IPC: G03B17/04
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To prevent many peripheral subjects which are not viewed from being photographed and to prevent the subject from being unexpectedly photographed small by arranging a four-sided convex mirror by opposing it to the subject and specifying the ratio of an area where the subject can be viewed through the convex mirror with respect to a picture on a film. SOLUTION: The four-sided convex mirror 2 is arranged by being opposed to a subject. Besides, the area where the subject can be viewed through the mirror 2 is set to be 80% to 95% of the picture formed on the film by a photographing lens 1. Then, a unit is held by a left so that the lens 1 is made to face a photographer him/herself and a composition is decided by projecting the photographer him/herself at the mirror 2. Thus, the photographer him/herself can be photographed. Since the mirror 2 is fixed to the front surface, an error is reduced as a finder projecting the photographer him/herself. By setting the ratio of the area where the subject can be viewed through the mirror 2 is set to be high with respect to the picture on the film, that many peripheral subjects are photographed or the subject is unexpectedly photographed small is eliminated.

Title: Volume recovery processing system
Inventor: YOSHIDA HIROSHI
IPC: G06F11/00
Filed: 1988-07-27
Abstract: PURPOSE:To properly use respective countermeasure means in one volume by dividing the volume to mini volume areas and providing a mini volume management table and reading contents of the mini volume management table to take respective counter-measure means. CONSTITUTION:For example, data to be written in a temporary file private area is written by using a mini volume area 7-4 and is handled as data for which only reinitialization is required at the time of error. Respective mini volume areas 7-i are used to perform preferable recovery. When error occurs in a volume 1, an input/output supervisor 2 starts a recovery management program 5. The recovery management program 5 reads contents of a mini volume table 6 to start the program so that a preferable recovery means is taken for each mini volume. Thus, the number of provided volumes is reduced.

By means of a detecting signal for a combustion flame, a microcomputer outputs a signal, responding to running of an engine, to a temperature set part to heat and control the heater 8 to a temperature of 300-700 deg.C. Namely, after running of an engine, the temperature of the heater 8 is controlled by means of a signal by means of which the running state of an engine is monitored so that the temperature of the detecting part of the fiber 5 for detecting light is maintained at a value at which a combustion prod is difficult to adhere. Since a combustion prod is prevented from adhesion before it is adhered, the combustion product can be prevented from adhesion by means of a small amount of energy.

Abstract: PURPOSE:To designate an area with high operability by inputting several apex positions, and thereafter, inputting an auxiliary point in the end, deriving an intersection of a segment for connecting this auxiliary point and the last apex, and the other segment and determining a polygon by setting this intersection as one apex. CONSTITUTION:Pieces of (n) apexes, for instance, five pieces of apexes (P1 - P5) are inputted, they are displayed successively on a screen, and also, a segment for connecting the points inputted successively is displayed simultaneously. Subsequently, when an auxiliary point Px is inputted, it is recognized that a segment P5Px has an intersection Q with a segment P1P2. In this case, when it is assumed that a segment PnPx makes an intersection Q with a segment P1 Pi + 1, an (n -i + 1) angle shape in which the points Q,(Pi+1)-Pn are apexes is determined. For instance, in the case of (n) = 5 and (i) = 1, a pentagon in which points Q, P2, P3, P4 and P5 are apexes is determined. In such a way, an area can be designated with high operability.

Abstract: PURPOSE:To prevent a variation in torque at low speed by a method wherein the count value of a counter is sampled based on the output pulses in a rotary encoder and the frequency of motor applied current pulses is controlled in accordance with the count value. CONSTITUTION:With start pulses applied, clock pulses (a) are applied to a retriggerable mono multi-vibrator RM, so a constant level continuous current is supplied to a motor MR.
