Title: Crystallization apparatus
Inventor: NAKASHIKI TAKEHIKO
IPC: B01D9/02
Filed: 1982-07-06
Abstract: PURPOSE:To reduce scaling, by moving a set ring region into a crystallizing canister to avoid cooling due to the air. CONSTITUTION:A buffle plate 7 surrounds the outer periphery of a draft tube 4 in such a manner that a set ring region 6 is formed in the crystallizing canister 1 remote from the canister wall thereof, that is, just to the outer periphery of the draft tube 4 and the upper part thereof is closed while the lower part thereof is opened. By moving the set ring region 6 into the crystallizing canister 1, cooling due to the air is eliminated and scaling is extremely reduced. In this case, a mechanism wherein fine crystals are withdrawn from the set ring region 6 to be supplied to a heater 2 through a recirculation pump 10 and dissolved under heating to be imparted to the crystal stayed in the canister 1 as oversaturation is similar to that of a conventional canister.

Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To easily gather and take out coins by forming recessed/projecting surfaces on the bottom surface of a coin tray so that the bottom surface of the coin is prevented from being closely stuck thereto. SOLUTION: A coin tray 7 is formed of a front wall 8a, a circumferential wall 8 constituted of left/right side walls 8b, 8b, and a bottom wall 9 and the whole surface of the upper end is opened. The bottom surface of the bottom wall 9 is formed into a recessed/projecting surface 10 having a flat projection parts 10a and a curved recess parts 10b provided alternately in the longitudinal direction of the coin tray 7. As for the coin tray 7 having the bottom surface formed into the recessed/projecting surface 10, the edge of a coin C faced to the recess parts 10b with the bottom surface of the coin C being in contact with the bottom surface can be caught by the tip of a finger F so that the coins C left few can be easily taken out.  When the projection part 10a and the recess part 10b are formed into circular, the coin C supported by the projection part 10a is largely inclined and the edge is projected high on the recess part 10b so as to be easily caught by the tip of the finger.

IPC: H01J9/227
Filed: 1985-05-31
Abstract: PURPOSE:To control defects such as graphite patches produced owing to the decrease of ammonia content in a graphite solution, by using an ammonia water of a specific density as a developing solution for a washing and removing process of the unexposed portions of a photoresist. CONSTITUTION:Some 5% of ammonia is included originally as a dispersion agent in a graphite solution for forming a graphite film, and the ammonia water can remove a photoresist up to about 98-99%. In the development with the present pure water washing, about 4% of a photoresist remains, which is dissolved and removed in a graphite solution sprayed in the following process of graphite film forming, and mixed in the recovered graphite solution as an impurity, causing to produce whitish stain (whitish fading) defects and the like. Therefore, an ammonia water of more than 10% density is applied to blow for a washing process.

Filed: 1979-09-11
Abstract: PURPOSE: To ensure a smooth retrieving by detecting the record track position of the document information by the scale signal generator provided to the linear motor which drives the linear actuator.  
     CONSTITUTION: The scale signal generator 45 incorporating the linear motor 30 generates the scale signals A and B in accordance with the shift of the motor 30. The signals A and B are led to the signal converter 49 and then switched with every 90°-phase to be delivered in the form of the saw-tooth type reference signal C. The signal C is led to one input of the differential amplifier 51 via the buffer amplifier 50 as well as to the sample holding circuit 52. The circuit 52 gives an access to the desired track by the track detector 53 for detection and thus holds the signal C. Then the feedback circuit is provided to give a servo control to the working position of the linear motor based on the differential between the sample holding value and the signal C.

Title: Method for controlling sheet width of hot rolled coil
Inventor: KAZAMA TSUNEO
IPC: B21B1/26
Filed: 1989-05-10
Abstract: PURPOSE:To maintain the specified width of a hot rolled coil and to improve yield by predicting the fluctuation in the width on the outlet side of a finishing mill at the time of a highly accelerated rolling by the temp. change in the finishing mill and compensating a bar width. CONSTITUTION:The temp. change in the finishing mill 6 or the fluctuation in the sheet width between the inlet side and outlet side of the finishing mill 6 generated with this change is previously predicted from the change in the rolling conditions of the mill at the time of the accelerated rolling and the bar width to meet the fluctuation is changed in the longitudinal direction of the target width on the rough outlet side. The finish rolling is executed by compensating the width in this way. The sheet width on the outlet side of the finishing mill is thus so controlled as to be kept constant.

Collector terminal voltage of the phototransistor Tr is introduced to a reversal input terminal of a comparator A1 as output voltage. Standard voltage obtained by dividing pressure of power voltage by series circuits of two resistors R5, R6 is introduced to a normal input terminal of the comparator A1. Consequently, when emission amount of the light emitting diode D decreases due to use for a long time or an output characteristic decreases because of decrease of a light receiving characteristic of the phototransistor Tr, this standard voltage is varied by an output decrease compensation circuit 1.
