Abstract: PURPOSE:To reduce the positional deviation of an original reading sensor so as to improve the reading quality of an original reader, by providing a member which controls the movement of a moving table sliding along guide rails in the direction normal to the sliding direction right below or right above the position where the sensor is provided. CONSTITUTION:An original reader is composed of a moving table 10 equipped with vertical walls 11 at both end sections, sliding members 4 at four corner sections on the lower surface of the moving table 10, guide rails 1, driving device (not shown in the figure) which moves the moving table 10, and original reading sensor C. The sensor C electrically scans a picture in the direction almost normal to the moving direction of the moving table 10 and forms an image. The table 10 is placed on the guide rails 1 by means of the sliding member 4 and, at the same time, positioned in the direction shown by the arrow B by swing preventing sliding members 2 and 3 which hold the rails 1 between them. The sensor C is provided right above the positions where the members 2 and 3 are provided. Therefore, positional deviation of the sensor C is reduced and the original reading quality is improved.

Title: Method for oxidative disposal of high cod waste water
Inventor: CHIN CHIYUUKITSU
IPC: C02F1/72
Filed: 1991-04-09
Abstract: PURPOSE: To effectively reduce COD by regulating the pH value of waste water to a specific range and adding an oxidizing agent while controlling temp. to a specific range, thereby oxidizing and decomposing the org. matter in the waste water.  
     CONSTITUTION: The oxidizing agent is added to the waste water while adjusting the pH of the waste water to about 6 to 13 and controlling the temp. to about 40 to 95°C, thereby oxidizing and decomposition the org. matter in the waste water. The oxidizing agent to be added to the waste water is, for example, KMnO 4 , H 2 O 2 , Na 2 S 2 O 5 , (NZH 4 ) 2 S 2 O 8 , NaOCl, bleaching agents, etc. Then, the collapse of the org. matter micelles in the waste water is made possible, the contact chances of the oxidizing agent and the org. matter are increased and active energy barriers are degraded by adjusting the pH value. If the temp. is regulated in this state, the decrease of the COD may be attained by rapidly and thoroughly oxidizing and decomposing the org. matter.

Title: Lead frame and manufacture thereof
Inventor: HAMAMURA KIYOTO
IPC: H01L23/50
Filed: 1981-05-22
Abstract: PURPOSE:To effectively partly plate at the end of a lead frame by forming the sectional shape in the vicinity of the end of the lead frame nearly in trapezoidal shape. CONSTITUTION:A vinyl chloride mask 25 is covered on a main surface 221 except the partly plated part 23 of a lead frame 20, an Si rubber plate 26 is placed  on the other main surface 222, and is pressed through a plate 27.

When it is plated in this state and  the prescribed part is partly plated at the part 23, an excessively plated part is  not produced at all, and even if mechanical or thermal impact is applied to the  pins 22, a shortcircuit accident due to the excessively plated part can be avoided  between the pins, thereby obtaining a lead frame having pre ferable characteristics. When photomasks of different shape and size are formed on the main surfaces 221, 222 and are etched, a lead pin of sectional shape of nearly trapezoidal  shape having an oblique surface 24 can be obtained.

Abstract: PURPOSE:To secure a wide range of the output voltage operation, by connecting the serial circuit of the NPN and PNP transistors to the output end of the differential amplifier and at the same time giving the negative feedback to the output toward the reverse input end of the differential amplifier. CONSTITUTION:Transistor TR1 gives the reverse amplification to output voltage V0 of differential amplifier A1 to which two input voltages v10 and v20 are supplied, and sends its output voltage to TR2. Then TR2 gives the reverse amplification to the input voltage given from TR1 for output and at the same time the negative feedback to output voltage E0 toward the reverse input terminal of amplifier A1 via resistor R14. Furthermore, the negative feedback is given to voltage v0 toward the same reverse input terminal of A1 from the output end of A1. Thus a wide range of the output voltage operation can be obtained for the differential amplifier.

Abstract: PROBLEM TO BE SOLVED: To reduce the frequency of re-purchasing and to reduce the possibility of illegal use by using a card for the identification confirmation of the prepay of monetary value without storing remainder information in the card, so as to prepay a large amount of money. SOLUTION: An ID card to rent a user is registered in a repeating device 2 by using a counter terminal and inputs the prepaid amount from the terminal 1. The device 2 holds information of the prepay, consumption, of each ID as a database. The user sets the ID card received at a counter to a reading device 3, which transmits ID to the device 2. The device 2 transmits prepaid remainder corresponding to corresponding ID from a database to the device 3. When consumption is executed, the device 3 transmits the amount of the consumption to the device 2, which updates the prepaid remainder by subtracting the amount of the consumption from the prepaid remainder corresponding to the ID.
