Title: Peeling method for optical disc board and taking out apparatus
Inventor: UEDA KEIJI
IPC: B29C45/42
Filed: 1994-04-25
Abstract: PURPOSE:To obtain a uniform optical disc board having no warpage by blowing peeling air from a bore of the board to a close contact surface of the board with a stamper and releasing the board from the stamper. CONSTITUTION:The method for peeling an optical disc board takes out the board molded in a cavity by filling resin in the cavity from molds. The methods comprises the steps of first releasing only a board mirror surface side while an information surface side of the board 1 remains brought into close contact with a stamper 4, and then blowing releasing airs 7, 7a from a bore of the board 1 toward a close contact surface to release the stamper 4 at the contact surface of the board 1 with the stamper 4. It is preferable to move an ejector sleeve 6 for a cut punch 8 and a molded form protruding to a position slightly reverse to the molded form protruding direction from the stamper surface. Thus, the entire surface of the form is uniform without generating warpage.

IPC: H01L21/02
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To indicate the fluctuation and trend of semiconductor manufacture data in a short time without performing re-calculation, and to reduce a data storage area. SOLUTION: The totalized result of semiconductor manufacture data is preserved for each hierarchy, and the preserved data in each hierarchy are indicated so that fluctuation and trend can be judged. The statistics of the number, minimum value, maximum value, sum, and sum of squares is used as the totalized results so that the totalized result in each hierarchy can be calculated by calculating statistics 43 of the hierarchy only from statistics 41 in the hierarchy ranked lower than the hierarchy by a statistic data calculating function 42 without performing any re-calculation from the data in the least significant layer. Also, any hierarchical data unnecessary for indicating the fluctuation and trend are deleted.

Title: Purification of ketones
Inventor: MIKI HISAYA
IPC: C07C67/00
Filed: 1977-09-13
Abstract: PURPOSE: To reduce the aldehyde content of a crude ketone containing small  amount of aldehydes and acidic substances, by contacting the crude Retone with an alkali, and heating in the presence of an anion exchange resin followed by distilling, thereby keeping the activity of the anion exchange resin for a long time.  
     CONSTITUTION: Purified ketone is obtained by contacting a crude ketone containing small amounts of aldehydes and trace of acidic substances, which is obtained by the acid dedomposition of an aralkyl hydroperoxide, with an alkali, heating the ketone in the presence of an anion-exchange resin having sites of hydroxyl group type quaternary ammonium salts, and subsequently distilling the treated ketone. Since acidic substances form salts with the alkali, and no longer undergo ion-exchange with the anion-exchange resin, the activity of the anion-exchange resin is kept for a long time. The alkali is used in an amount of at least equivalent weight to the acidic substances. When the concentration of the acidic substances in the crude ketone is not definite, excess alkali is used in order to separate the mixture into two layers and crude ketone of the upper layer is brought into contact with the anion-exchange resin.

IPC: B21D9/03
Filed: 1982-06-28
Abstract: PURPOSE:To restrict a flattening of pipe and a generation of folds, and to control the pipe flattening and a decreasing degree of the wall thickness of pipe, by arranging tops, equipped with elastic cushioning materials, opposingly to each other on both sides of a pipe axis, and providing forces, in the radial directions of the pipe, to the tops by pressing-force-transmitting members. CONSTITUTION:A device for prevneting the flattening of a pipe is assembled from tops 7 each of which has an elastic cushioning material 8 attached to its outside, mandrels 9 which have truncated-conical-frustum shapes and are connected to each other by connecting connecting-rods 10 with the aids of pins, and reaction-receiving frames 15 used for supporting the mandrels 9 and the tops 7 movably in the radial direction of the pipe, etc.; the device is inserted into the pipe P. When a pressure is applied to the mandrel 9 in the pipe P by an external force such as a hydraulic jack 13, the tops 7 are expanded to the direction of the pipe wall by a wedge action of the mandrel 9 because the movement of the top 7 in the longitudinal direction of the pipe P is restricted, so the gap between the inner wall of the pipe P and the outer surface of the device is closed. The pipe is bent in this state. After the bending work, the device is easily taken out of the pipe by releasing the force of the jack 13.

Abstract: PURPOSE: To prevent the incomplete combustion caused by a pressure rise and flow increase in change-over, by preopening a butterfly valve of a flue in a buttery on the side of no change-over before changing over the heating of plural batteries to increase the inflow rate of combustion air.  
     CONSTITUTION: Timer circuits 22a and 22b are provided for each battery, and operated according to the change-over of batteries A and B. For example, in changing over a row a to a row b, change-over starting signals of reversing cocks 7a in distribution gas branches 5a of the battery A and given by "ON" of a clock contact 21 to sound an alarm of heating gas change-over. The timer circuit 22b acts at this time to operate a solenoid 23b, and a butterfly valve 12 on the battery B side is forced to open before the cocks 6a are closed. The pressure in the flue draft of the battery B is reduced, and then the cocks 7a are closed. If the pressure in a main heating gas duct 1 rises, the increased flow rate of air into the battery B prevents the incomplete combustion of the heating gas.

The tap coefficient device 15-1 is provided with a positive pulse coefficient device 19 and a differential coefficient device 18 stored with a difference error between positive and negative pulses, and the changeover corresponding to the positive/negative pulses is applied by using a switch 21. All outputs being the result of addition of all outputs of the tap coefficient devices 15-1-15-N by an adder 16 are outputted from an output terminal 13 as the entire output of the applied filter. Since all the positive/negative coefficient devices are set simultaneously up to the linear region without adding a special hardware, the converging time is not almost increased.
