Title: Sludge searcher
Inventor: TAKAHASHI HIDEYUKI
IPC: G01F23/296
Filed: 1980-11-18
Abstract: PURPOSE:To eliminate measurement errors owing to a difference in rise times by deviating the transmission timing of both ultrasonic wave signals by the time corresponding to the difference in the rise time of received output waveforms. CONSTITUTION:First, ultrasonic signals S3, S4 of high and low frequencies from transmitters and receivers 8, 9 are reflected by an artificial reflection body 25 and are received in the transmitters and receivers 8, 9. The difference (t) in the times counted by depth counting circuits 13, 14 in a subtraction circuit 24 is transmitted to a delay circuit 23, and the (t) is subtracted from a set time T, by which a delay time is set. Next, the body 26 is removed. When a transmission timing pulse is generated in a circuit 22, it is delayed by T-t by the circuit 23 and is transmitted via a circuit 25 to a pulse generating circuit 3, from which the pulse-like signal of a low frequency is generated and the ultrasonic signal S2' of the low frequency is emitted from the transmitter and receiver 9 through an amplifier 5 and a transmission-reception selector 7 toward a sludge layer 20. The ultrasonic signal S1 of a high frequency is emitted from the transmitter and receiver 8 by the similar operation, and depths D1, D2 are calculated by the circuits 13, 14.

Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To attain charge imposition every time a recorded broadcast signal is reproduced by providing a key acquisition means to acquire a decoding key externally. SOLUTION: A communication section 51 as a key acquisition means makes communication with a key management center 8 when a broadcast signal recording reproducing device reproduces program recording data to receive a ciphering key 53a and a decoding key 54a. When the key management center 8 sends the ciphering key 53a and the decoding key 54a to a communication section 51, charge is imposed onto a viewer making the transmission request. A decoding circuit 54 uses the decoding key 54a to decode program recording data to be outputted and reproduced from a recording device main body 55, a ciphering circuit 53 uses a new ciphering key 53a to cipher again the signal outputted from the decoding circuit 54 and the result is outputted to the recording device main body 55. Thus, every time same program recording data are decoded, the data are ciphered by a new key and then rewritten.

Title: Method for forming thin cuinse2 film
Inventor: YOSHIDA TAKASHI
IPC: H01L31/04
Filed: 1990-06-21
Abstract: PURPOSE:To enable a thin CIS film with less crystal defect and a flat surface to be formed and conversion efficiency to be improved by eliminating a grain boundary part of a polycrystalline film by a process for forming the CIS polycrystalline film and a sputter etching process. CONSTITUTION:An Mo layer 2 is formed on a glass substrate 1, each layer of Cu, In, and Se is laminated on the layer 2, and it is calcined at approximately 300-600 deg.C in nitrogen. Therefore, a polycrystalline film consisting of a CIS crystal grain 3 is formed but a grain boundary part 4 with much defect having a low density which deviates from chemical stoichiometric composition is produced at the crystal grain boundary. Then, a surface of the substrate 1 is subjected to sputter etching, thus enabling the part 4 to be eliminated. By performing sputter etching again, the grain boundary is embedded with CIS which jumps out by sputtering and is subjected to crystal growth, thus obtaining a high-quality thin CIS film with a high density. After this, the CIS film is formed again and elimination of the part 4 due to sputter etching and crystal growth are repeated, thus forming the CIS film with a flat surface and enabling conversion efficiency to be improved.
