Title: Purification of malic acid
Inventor: YOKOTA KENJI
IPC: C07C51/00
Filed: 1979-03-22
Abstract: PURPOSE: To obtain purified malic acid containing no or a remarkably reduced amount of maleic acid, and useful as a food additive, by treating an aqueous solution of crude malic acid containing maleic acid with a strong basic cation exchange resin at an elevated temperature.  
     CONSTITUTION: An aqueous solution of malic acid containing maleic acid is passed through a strong basic cation exchange resin bed at ≥35°C, esp. ≥40°C, to purify malic acid. The above ion exchange resin is preferably the II-type resin, since it can be easily regenerated with an alkali. When the concentration of maleic acid in the aqueous solution of malic acid flowed out of the resin bed exceeds the tolerance limit, the flow of the solution is stopped and the resin bed is regenerated. The regeneration of the pref caried out resin is as follows: the aqueous solution of malic acid is forced out of the resin bed with air, water is passed through the bed to desorb a part of adsorbed organic acids, and then an aqueous solution of an alkali is passed through. The temp. can be raised to 40W70°C when the I-type resin is used; and ≤55°C when the II-type is used.

Title: Battery back-up device
Inventor: MARUYAMA KOJI
IPC: G11C5/00
Filed: 1991-02-28
Abstract: PURPOSE:To prevent a volatile memory from breakdown by turning a read switch incorporated in a memory card on only when an external battery back-up power unit is completely inserted. CONSTITUTION:When a memory card 1 is completely inserted in an external battery back-up power unit 2, a read switch 8 is turned on due to a read switch 8 in a magnetic flux generated by a magnetic flux generator 7. Voltage is then supplied to a volatile memory 3 from an external back-up battery 13 through a back-up power supply output terminal 12, a program power supply input terminal 11 and the read switch 8. Also, when the memory card 1 is not completely inserted, the read switch 8 is still in an off state since magnetic field enough to turn it on is not applied. Therefore, the volatile memory 3 is not supplied with the voltage even if a program voltage is added from the program power supply input terminal 11. Consequently, time for back-up is prolonged.

Abstract: PURPOSE: To accurately discriminate a vehicle located in the fixed area of a road one by one at night by discriminating the vehicle based on each image picked up nearly at the same time by varying the incident light quantity of a TV camera in two stages, detecting the superposition of the vehicle and detecting the vehicle from which the superposition is eliminated. CONSTITUTION: Two images are obtained by image-picking up the road nearly at the same time by adjusting the TV camera 1 in the two stages when the road is image-picked up with the TV camera 1. A vehicle discrimination part 24 discriminates the vehicle based on the two images image-picked up nearly at the same time by varying the incident light quantity. A vehicle detecting part 25 detects the vehicle from which the superposition of the vehicle located at the same position is eliminated considering the superposition of a discriminated vehicle.  For example, a vehicle body is detected based on the image image- picked up by increasing the incident light quantity even when the vehicle putting off a headlight is located in the neighborhood of the TV camera 1, and the headlight of the vehicle located far from the TV camera is detected based on the image image-picked up by decreasing the incident light quantity.

Title: Discriminating device for multi-pcm sound signal and video signal
Inventor: KATAOKA KAZUHIRO
IPC: G11B20/10
Filed: 1986-02-18
Abstract: PURPOSE:To simplify a circuit constitution by discriminating a signal whether it is a vertical synchronizing signal or not by the pulse width of the signal obtained at the output of a vertical synchronizing signal separation circuit. CONSTITUTION:In a multi-PCM reproduction time, no pulse is inputted to the input 13 of a discrimination circuit 7 when a recording is performed only on a PCM recording dedicated track, but at a time except the above, a pulse signal having a wide pulse width is inputted to it. The discrimination circuit 7 can discriminate the signal whether it is the vertical synchronizing signal or not, by detecting the pulse width of an inputted pulse signal. Since an FM demodulation circuit, and the vertical synchronizing signal separation circuit can be used as they are, a switching between a video and a multi-PCM signal can be obtained with a simple circuit constitution.

Filed: 1991-02-28
Abstract: PURPOSE:To improve confortableness and energy conservation effect by a method wherein, in an air conditioning machine equipped with a variable capacity compressor, the operation pattern of the compressor is set based on the difference between an indoor temperature and a predetermined temperature and its output frequency is shifted under stepwise control and, when the predetermined temperature is reached, the shift control width is made narrow. CONSTITUTION:When the operation of an air conditioning machine is started with controls 31 set, for example, at a heating mode and at a desired room temperature, an indoor control part 21 reads out the operation pattern at the time of heating operation, obtains the difference between the indoor temperature and the predetermined temperature from a room temperature sensor 22 and identifies the operation pattern corresponding thereto. If the control difference is within a predetermined range, a command code is sent to an outdoor control part 11, which obtains output frequency F to start a compressor motor 1M. This control part effects shift control of the output frequency according to the operation pattern until the predetermined temperature is reached, at which point the shift control width is made narrower than usual in the output frequency region at that time.
