IPC: G11B15/46
Filed: 1991-03-29
Abstract: PURPOSE:To enable high-density recording to be conducted and to prevent crosstalk jamming caused by a pilot signal in the case of reproduction by using the periodical change of accumulated electric charges as the pilot signal corresponding to the increase of a density ratio. CONSTITUTION:A 8-15 conversion part 6 selects and outputs one code based on an inputted 8-bits data language, control signals (a-c) from a comparator 5 and the final two bits of an encoded word before being stored in a latch circuit 7. When the control signal is (a), the conversion part 6 selects the encoded word having the -1 or -3 charge total (CDS) in one encoded word, when the control signal is (b), the encoded word having +1 or -1 CDS is selected and when the control signal is (c), the encoded word having the +3 or +1 CDS is selected. Simultaneously, the final two bits of the encoded word are applied to the circuit 7, and a current value RDn+1-RDn of the accumulated electric charge is applied to an adder 2. Then, a parallel encoded word from the conversion part 6 is converted to the serial data modulating signal of 15 bits by a P/S conversion part 8.

Title: Digital radio telephone system
Inventor: TANAKA HIRONORI
IPC: H04W72/12
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To allow radio channels of a base station to be efficiently utilized by slave sets. SOLUTION: In the case that a radio slave set PS makes a call when radio speech channels of a base station BS are fully occupied and no channel is available, the base station sends channel fully occupied data to the slave set and the slave set receiving the data sends reservation information to the base station. When any channel is released and idle in the base station, the base station reserves the idle channel and informs the reserved notice to the slave set. The slave set receiving the notice immediately makes redialing, resulting that the speech of the slave set is made through the reserved idle channel.  Thus, in the case that the speech is not available because of fully occupied radio channels, redialing by the slave set having otherwise been repetitively tried till connection to opposite party is made is avoided, resulting that the slave set uses radio channels of the base station efficiently.

Abstract: PROBLEM TO BE SOLVED: To facilitate manufacture while reducing the cost and to increase heat storage per unit volume while suppressing fluctuation in the heating temperature of a fluid to be heated by providing every other channel of a ceramic honeycomb arranged in vertical direction. SOLUTION: A heat storage body 1 is a honeycomb 2 made of ceramic, e.g. alumina, having a large number of square channels 3 defined by ceramic walls 2a. The honeycomb 2 is disposed with the channel 3 directing in the vertical direction and every other channel 3 is filled with a substance 4 changing phase between solid and liquid depending on the working temperature. Since a fluid channel 3 is adjacent to a part filled with the phase changing substance 4 in the honeycomb 2, heat transfer takes place between the substance 4 and air flow 9 when it is fed through the channel 3. When the heat storage body 1 is heated, the substance 4 makes a transition from solid phase to liquid phase and stores a significant quantity of thermal energy in the form of latent heat in the heat storage body 1 through phase change.
