Title: Magnetic tape controller
Inventor: MIYAOKA SEIJI
IPC: G06F3/06
Filed: 1991-09-17
Abstract: PURPOSE:To prevent the discontinuation of transfer of the data to a buffer from a host device. CONSTITUTION:A synchronizing signal 7 of a low speed is used for transfer of the data to a write buffer 1 from a host device 20. The transfer of data to the buffer 1 from the device 20 is asynchronous with the transfer of the write data to a magnetic tape device 30 from the buffer 1 with intervention of a write modulation circuit 4. Thus the signal 7 is switched to a low speed operation mode when the idle area of the buffer 1 is reduced. Therefore it is possible to reduce the discontinuation frequency of the transfer of data due to a filled state of the buffer 1 and to improve the transfer efficiency of data. Then the reliability of a magnetic tape controller is improved.

Title: Method for forming thin film
Inventor: OKABAYASHI HIDEKAZU
IPC: H01L21/26
Filed: 1985-10-21
Abstract: PURPOSE:To enable a thin film of a high-melting point material or a high-purity thin film to be formed by using a halide gas or a hydride gas as the source gas for forming a thin film in the cluster ion beam evaporation method. CONSTITUTION:When, after evacuating a vacuum vessel 1 from an exhaust vent 2 to an extent of 10<-5>Pa, a source gas is introduced from a gas supply port 7 into a gas introducing pipe 3, the source gas is jetted by adiabatic expansion from a jetting port 4 into the vacuum vessel 1, forming clusters (bulk molecule groups). A portion of them is ionized when passing through an ionization mechanism 10, and is projected on the substrate surface and decomposed, forming a film. A WF6 gas is used as the source gas, and a thin film is deposited at a substrate 13 temperature of about 400 deg.C with a hydrogen gas simultaneously flowing from an auxiliary gas introducing pipe 9. Since a gas is used as the source material in this way, a thin film of a high-melting point material can be formed, while high-melting point material could not be deposited by the method using a solid as the source. In addition, a halide gas such as Mo, Ta or Ti or a hydride gas such as SiH4 can be used instead of WF6.

Title: Automatic teller machine
Inventor: MATSUI YASUTO
IPC: G06Q40/00
Filed: 1993-09-22
Abstract: PURPOSE:To shorten the time of a money to be withdrawn transaction and to improve the operation efficiency by inputting a password and an amount of money in the reverse order to the conventional order, and sending and receiving a message when the money amount input operation ends. CONSTITUTION:A user inserts a magnetic card C into a card insertion slot and inputs an amount of money to be withdrawn. In response to the input of the amount of money to be withdrawn, a transaction request message is generated and sent to a host computer by a transmission control part 23. Then a transaction (money withdrawn) permit message as a transaction answer message including a password number is received through the transmission control part 23 while the user inputs the password number. Then when the result of collation with the password number by the main control part 11 indicates a coincidence, a paper money reception/payment unit 15 is put in operation to discharge prepared paper money from a paper money insertion slot. Thus, the transaction message is sent before the customer completes the input operation, so the wait time up to the reception of the transaction permit message after the end of the operation is eliminated to shorten the time of the money to be withdrawn transaction.

Title: Semiconductor laser equipment
Inventor: MASAKI KATSUMI
IPC: H01S5/068
Filed: 1990-09-06
Abstract: PURPOSE:To keep the extinction ratio constant independent of temperature change, and facilitate adjusting, by a method wherein, in the state that high frequency wave of a specified amplitude is superposed on an input pulse signal, the detected signal is compared with a preset reference value, and fed back to the input signal on which the high frequency wave is superposed. CONSTITUTION:In a signal route reaching an LD driving transistor 4 from an input terminal 1, an adder 3 is inserted, with which a high frequency oscillator 2 outputting high frequency wave of specified amplitude is connected via a gate circuit 23. Said circuit 23 is opened and passes the high frequency signal, only during the 'high' period of the input pulse, so that the high frequency signal of specified amplitude is superposed on the input pulse signal only during the ON-level period. On the other hand, a bandpass filter 9 is connected with the output side of a preamplifier 8 amplifying the output of a PD 7, and the superposed high frequency signal is extracted from the output of the preamplifier 8. The extracted signal is delivered to a peak detection circuit 11, converted, and compared with a preset reference voltage 13 via a comparator 12. The output of the comparator 12 is sent to the base of a transistor for gain adjustment, and negatively fed back to the input pulse signal on which the high frequency signal is superposed.

IPC: G06F21/10
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a digital data recorder with secrity information which prevents digital data from being falsified, reproduced, partially used, or illegally used. SOLUTION: A CPU 3 generates a public key and a secret key by a public key cryptosystem. Then, an ID image stored in a security memory 8-1 is used as a random number series source. Moreover, the CPU 3 appends additional information to the image data inputted from a pickup system 1, and encodes the data with the secret key, to generate an electronic signature data. Further, the CPU summarizes the input data main body to which the additional information is appended, the electronic signature data, and the public key, etc., an generates a data file. In the case of restoring the data file, if the data acquired by decoding the electronic signature data by using the public key appended to the data file coincides with the data acquired from the main body of the data file, it can be judged that neither falsification nor edit, etc., are added thereto.

Title: Insulation structure in joint portion of power cable
Inventor: TAKAHASHI SUSUMU
IPC: H01R43/00
Filed: 1989-09-14
Abstract: PURPOSE:To restrain any generation of water tree (water penetration like a tree pattern) by using an insulating tape incorporating a crosslinking agent and an antioxidant into a specific polyethylene. CONSTITUTION:An insulator constituting a conductor joint part is formed of a tape made by adding a crosslinking agent and an antioxidant to polyethylene having a low crystallinity and density of 0.89-0.91g/cm<3>. Since the crystallinity of polyethylene(PE) is low, solubility of the crosslinking agent or antioxidant is high. In the case of formation in a tape shape, bloom generated on the tape can be reduced. With the density of 0.89-0.91g/cm<3> of PE, an insulator having a remarkably reduced generation of water tree can be formed. Therefore, any generation of the water tree can be restrained so that insulation of a cable can be enhanced.

IPC: G06T1/00
Filed: 1986-10-07
Abstract: PURPOSE:To reduce the capacity of an image memory by detecting the varying part of a binarized signal sliced in density other than a standard level with an exclusive OR to the binarized signal of standard density and compressing information with length coding. CONSTITUTION:A binarizing slice circuit 3a performs binarization in the standard density and stores this coded result in an image memory 9. The circuits 3b-3d perform binarization in the density other than a standard level. These binarized signals and the signal of the standard density are corrected by exclusive OR circuits 4a-4c in accordance with the density. A correction data generator 7 turns a correction signal into a run length code to store it in a correction data memory 10. A correction signal generator 11 reads the correction data out of the memory 10 in response to a slice level at the time of reading the memory 9. Then the correction data is inputted to an exclusive OR circuit 4d and a slice selection signal 12 outputs an output signal 13 of designated density. Thus it is possible to compress information and to reduce the memory capacity.
