Title: Rotation controller for optical disk and optical disk device
Inventor: NARA HITOSHI
IPC: G11B19/28
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a rotation controller of optical disk capable of shortening a servo pull-in time while performing a constant servo pull-in operation at the time of the quick access of optical pickup or the like. SOLUTION: From a state in which a first cutoff means SW1 and a second cutoff means SW2 are both cutting off the transferring of a revolving speed error signal SES, at first, the revolving speed error signal SES is transferred to a read operating clock generating means 12 by making the first cutoff means SW1 a releasing state and next, the error signals SES is transferred to a rotation driving signal generating means 13 by making the second cutoff means SW2 a releasing state. In short, a timing turning the servo of a spindle motor on is made to be delayed until a tracking servo is stabilized. Thus, the constant servo pull-in is performed at the time of the quick access of an optical pickup or the like to prevent the vibration or the like of an optical disk.

Title: Restoration signal transmission system for signal circuit
Inventor: TERASAKI YUTAKA
IPC: H04Q3/42
Filed: 1988-11-08
Abstract: PURPOSE:To release a load relay completely even if an open current of the load relay is small by connecting an earth transmission circuit to an output of a constant resistance circuit able to be switched into a low resistance state and a high resistance state with a control signal and sending an earth level to the output for a prescribed time when the constant resistance circuit is in the high resistance state. CONSTITUTION:The constant resistance circuit 1 reaches a low resistance state when a control signal CONT 1 sent from a control circuit 13 through a control line 14 is low level to a resistance changeover circuit 2 and reaches a high resistance state when the CONT 1 goes to a high level. Moreover, an earth transmission circuit 8 is connected to an output terminal 12 of the constant resistance circuit 1 and earth level is given to the output terminal 12 of the constant resistance circuit 1 when a control signal CONT 2 sent from the control circuit 13 through the control line 15 goes to a high level. When the constant resistance circuit 1 is at high resistance state, an earth level is sent to the output terminal for a prescribed time only. Thus, even if the open current of the load relay is small, the relay is surely released.

Inventor: SHIMIZU SHIGEMI
IPC: B05D3/10
Filed: 1994-11-15
Abstract: PURPOSE: To perform the dry washing of a precise part such as an LSI wafer by using active air. CONSTITUTION: An active air generator 1 is connected to a washing chamber 8. The active air generator 1 is constituted by combining a centrifugal force/ coriolis force generator 2 and a gas-liquid separator 4 and subjects water to ion dissociation treatment to form waterdrops in a revolving air stream and performs the activation treatment of the waterdrops and the ionizing treatment of an air molecule to form an air ion in the revolving air stream. The gas-liquid separator 4 separates waterdrops from the revolving air stream to take out active air and supplies active air to the washing chamber 8. The active air contains the air ion and a water cluster to form a high humidity atmosphere and comes into contact with the article to be washed in the washing chamber 8 while flows to wash the same.  The air ion netralizes the charge of the article to be washed and the water cluster releases a deposit from the surface of the article to be washed. The flowing active air peels the deposit from the article to be washed to remove the same.

Title: Quantitative determination method for secondary brightener in plating liquid
Inventor: NISHIKAWA TAKESHI
IPC: G01N27/416
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To obtain a quantitative determination method in which the concentration of a secondary brightener in plating liquid can be determined easily and precisely by applying a constant voltage in a state that a rotating electrode is at a standstill and in a state that the electrode is turned, measuring the precipitation speeds, and finding the ratio of the precipitation speeds in both states. SOLUTION: An Ni plating liquid which contains a secondary brightener as a test liquid 2 is put into a testing tank 1, and the ratio of a precipitation speed in a state that a rotating electrode 3 is at a standstill to a precipitation speed in a state that the electrode 3 is turned is found. The contact frequency of the secondary brightener with the electrode 3 is higher during its rotation than at its standstill, the precipitation obstruction action of the secondary brightener acts on the turning electrode 3 more according to its concentration, and the precipitation speed is lowered. Since the ratio of its reduction is proportional to the concentration of the secondary brightener, the concentration of the secondary brightener can be found on the basis of the ratio of the precipitation speed at the standstill of the electrode to that in its rotation.  When the secondary brightener in a proper quantity is replenished on the basis of a concentration value determined in this manner, a good plating treatment can be executed.

Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent an IC card from being illegally accessed even when the partial wire tapping of information in a special memory packaged in an IC card is permitted. SOLUTION: When an IC card 1 is inserted to an IC card reader/writer 3 and the cancel of access right is requested from the reader/writer 3, an arithmetic processing part 15 reads a random number from a random number generating processing part 11 and translates it to the memory address of a special memory 7. Then, a data read request is sent so as to read the data of that memory address out of the special memory 7 and to send them to an IC chip 5. The data from the reader/writer 3 are compared with data in a special memory managing table 17. When both the data are equal, the right of access is canceled to the readar/writer 3 and it is reported. When these data are not equal, an access right cancel error is judged and it is reported to the reader/ writer 3. At the same time, an access right cancel error counter 21 is activated and increment operation is performed.  When it is reported from the counter 21 a count value reaches a prescribed threshold value, it is reported through the reader/writer 3 to a center host and the IC card 1 is locked by itself.
