Title: Contents protection system of external storage device
Inventor: IWAMOTO AKIRA
IPC: G06F12/16
Filed: 1980-07-11
Abstract: PURPOSE:To avoid failure of a system by processing of software, by protecting the contents of an external storage device by means of restoring a part which is considered to have been broken down at the time of disconnection of an electric power  source of the external storage device, or rewriting-in a data, when the electric power source has been released. CONSTITUTION:A data is sent to a data buffer 5, a write-in amplifier 6 is operated, and when the data is written in a data track, if disconnecton of an electric power source occurs, the data cannot be sent halfway, and operation of the amplifier 6 is discontinued, too. As a result, a data is broken in the middle of an object track, a new data exists from a write-in start up to disconnection of the electric power source, except which an old data which has been written previously is left on the track. In this case, when the electric power source is released, a specific track information is read out by a read amplifier 7, is transferred to a CPU, an operation immediately before disconnection of the electric power source has occured is checked, the CPU retransfers a data or initializes a data track, and the contents of  an external storage device are held normally.

Title: Frequency demodulator
Inventor: OMATSU SHIGETOMO
IPC: H04L27/14
Filed: 1984-05-10
Abstract: PURPOSE:To simplify the circuit constitution and to reduce the cost by providing a filter part which transmits only a frequency component equivalent to either one of both digital binary information subjected to the modulation of frequency and a demodulating part which performs the demodulation of frequency to the output given from the filter part. CONSTITUTION:The frequency modulated digital binary coded signal recorded on a disk is modulated by the linear modulation characteristics 21. In other words, the information equivalent to the H level of the binary coded signal is modulated to a frequency f2 together with the information equivalent to the L level modulated a frequency f1 respectively. Then the modulated binary-coded signal is supplied to a BPF12 which uses the frequency f2 equivalent to the H level of the binary-coded signal as the center frequency. Then the BPF12 selects a signal equivalent to the H level of the binary-coded signal. The signal outputted from the BPF12 is demodulated digitally by an FM demodulation circuit 13 to the binary-coded signal obtained before modulation.

Title: Thermal transfer medium
Inventor: KUBO TAKASHI
IPC: B41M5/42
Filed: 1987-04-20
Abstract: PURPOSE:To enhance a heat resistance and a corrosion resistance, by a method wherein a compound selected from among alcohols, ethers, ketones, and a specific derivative is incorporated in a hot-melt substance layer formed on a substrate. CONSTITUTION:An accepting sheet is laid over a transfer sheet so that an accepting layer thereof is in contact with a transfer layer of the transfer sheet. A required transfer image is formed on the surface of the accepting sheet by applying a thermal printing from the reverse of the transfer sheet. At this time, a hot-melt substance in the thermal transfer layer melts due to heat and serves as a carrier in the transfer of a coloring dye or pigment. Because an ethyl cellulose used as a binder has a high melt viscosity, it functions as to enhance the melt viscosity of the whole transfer layer to further uniformly improve a transfer efficiency, thus realizing the uniformity of the transfer image. Moreover, the hot-melt substance melts into a loading material held by a high-heat resistance water-soluble resin in the accepting layer, whereby the coloring dye or pigment is fixed more securely and the rub resistance and the heat resistance are enhanced. The aforesaid accepting sheet is constructed by providing the accepting layer of the water-soluble resin and the inorganic or organic loading material on the surface of a substrate, such as a paper, a synthetic paper, and a plastic film.
