Title: Photodetector
Inventor: KURAHASHI AKIRA
IPC: H01L31/10
Filed: 1989-05-01
Abstract: PURPOSE:To enable the photodetector in specific wavelength to be performed by using a low cost device by a method wherein, when the first and second respective photodetecting parts are irradiated with the same light, different optical outputs are generated in the respective photodetecting parts and then the difference in these outputs are realized in the first wiring parts while the outputs amplified by an amplifier are made proportional to the photocomponents in specific wavelength bands. CONSTITUTION:Respective photocompoments of detected light are converted into current and then the photocomponents detected by the detecting parts PD1 become the current 1A running from n type impurity regions 6 to p type impurity regions 7 while the other photocomponents detected by the other detecting parts PD2 become the current 1B running from n type impurity region 8 to p type semiconductor substrate 3. The differences between the currents 1A, 1B generated in respective photodetectors PD1, PD2 are realized in wiring parts 4 to be amplified by a current amplifier 2 so that a voltage Eout represented by a formula I may be outputted to the output terminals of an operational amplifier 9. Through these procedures, the photodetection in specific wavelength enabled to be performed by a low cost device while the device having specific photodetection characteristics can be manufactured.

IPC: C07D207/28
Filed: 1985-05-25
Abstract: PURPOSE:To enable the mutual separation of pyrrolidonecarboxylic acid and glutamic acid from an aqueous solution containing said acids, with simple procedure, by taking advantage of the adsorptivity difference to a nonpolar porous synthetic adsorbent. CONSTITUTION:An aqueous solution containing pyrrolidonecarboxylic acid (abbreviated as PCA) and glutamic acid is made to contact with a nonpolar porous synthetic adsorbent (e.g. Diaion HP20) to effect the separation of both acids taking advantage of the adsorptivity difference of PCA and glutamic acid to said adsorbent. The contacting operation is carried out batchwise or using a column, however, column separation process is preferable. The column separation can be performed either by the chromatographic method comprising the pouring of the aqueous solution containing PCA and glutamic acid to the top of the adsorbent in the column followed by the elution of the adsorbed acid with water, etc., or by passing the aqueous solution through the column until the elution of PCA is about to begin. A high-purity solution of glutamic acid or PCA can be produced easily by this process.

CONSTITUTION:An image original of an optical size is set on an original placing table 1 of an image reader and an apex of the original is set at an original point position of the table 1. The length of the original edge side extending vertically and horizontally from the original point position is read based on the size value of an index Sz. Thus the size of the image original is known. When an image original having a size equal to an image reading range RA is placed on the table 1, it is decides that the size of the original is equal to '8'. Then this size value 8 is inputted via a key input device 23 as the reading range information. Under such conditions, a character string CS corresponding to the size value '8' is displayed on a CRT monitor 14 and the device 23 performs a reading operation in such a state. Thus a CPU 22 and a system control circuit 21 control the reading operations of an image reading head 2 carried out by a timing control circuit 9 in accordance with the value '8'.

Abstract: PURPOSE: To provide the subject method capable of carrying out constantly proper combustion of matters to be burnt irrespective of physical properties thereof (high or low ignitability) and requiring no such a special device as a combustion assisting burner or the like.  
     CONSTITUTION: In the case where the ignitability of matters to be burnt is high, the quantity of air to be supplied to the combustion zone is reduced without reducing the total quantity of combustion air thereby to suppress the combustion.
