Title: Heat accumulating apparatus utilizing hydrogenated metal
Inventor: SAKAI TAKASHI
IPC: F28D15/02
Filed: 1981-09-30
Abstract: PURPOSE:To recover heat of reaction while reducing loss of sensible heat, by charging  a hydrogenated metal in a hollow space formed at the central portion of a donut- shaped heat pipe so that hydrogen is passed through the hydrogenated metal, and  connecting a heat accumulating section and a hydrogen storing section to each other via a conduit. CONSTITUTION:Opposite open ends of an outer pipe 1 and an inner pipe 2 of a donut- shaped heat pipe are closed by end plates 4a, 4b, and a hydrogen feeding and discharging pipe 8 is connected to the end plate 4a. A hydrogenated metal 6 is charged in a  hollow space 5, and hydrogen is passed through a porous pipe 9 promptly. With such  an arrangement, hydrogen gas, generated by heating a heat exchanging section by a  heat medium carried to a heat exchanger and dehydrogenating the hydrogenated metal  through heating of the same, is carried to a hydrogen storing section, so that hydrogen  is stored as hydrogenated metal. On the other hand, in utilizing the apparatus for  accumulating heat, the hydrogenated metal is dehydrogenated by heating the same by  a low-temperature heat medium in which waste heat is collected, and heat, obtained by  reacting the hydrogen produced through dehydrogenation of the hydrogenated metal  with a metal at an electricity accumulating section, is transmitted to the heat medium.

Title: Video tape recorder
Inventor: INOUE HAJIME
IPC: G11B15/087
Filed: 1992-05-20
Abstract: PURPOSE:To surely enable the changeover of an operation mode at the break of a signal processing unit by adding identification data for identifying the signal processing unit and segment recording video signals, then changing over a reproducing mode to a recording mode in accordance with this identification data. CONSTITUTION:A recording signal forming circuit 2 divides digital signals to a synchronous block and records the signals by changing over the signals as identification data ID to frame ID, track ID and video ID. A system control circuit changes over the operation over the entire part to the reproducing mode after rewinding a magnetic tape by as much as several tracks in the case of execution of consecutive recording. An OR circuit 25 outputs a picture recording mode changeover signal SW by the detection of the frame ID, track ID and video ID. An FF circuit 26 outputs a changeover signal SEL in synchronization with the rise of the signal level of the signal SW when this signal level rises. A selection circuit 6 is thus changed over from the reproducing side to the recording side.

Title: Voice message store type selective call receiver
Inventor: TSUTSUMI TAKEHIKO
IPC: H04M3/42
Filed: 1984-07-25
Abstract: PURPOSE:To enable a user himself/herself of write and rewrite an optional message by providing a function to a selective call receiver so that the user can operate a selection switch for message writing address to write the message to a RAM. CONSTITUTION:A selection switch SW for message writing address is operated previously to give the A/D conversion to a voice message supplied through a mike M and to write it to a RAM via a control part CONT. The selection signal received by a radio receiver RF is identified by a decoder DEC. Then the message designation signal which is received consecutively is decoded by the DEC in case a selection signal is allocated to own. An access is given to the RAM via a control part with the address of said designation signal. Based on this address, the message stored previously in the RAM undergoes the D/A conversion and is outputted in voice through a speaker. Thus, it is not required for a carrier of a selective call receiver to give an immediate answer to a caller through a telephone even though said carrier receives a call. In such a way, the operation load of the user is reduced.

The luminance signal converted inversely, that is, the RGB signal is stored in the memory 8 and displayed on a CRT 9 and an image is printed out by a printer section 6. Thus, a final image with high accuracy is confirmed in a short time and a pre-view image with fidelity to a print image is displayed on the CRT 9.

As a result, the kerosene is diffused widely over the upper portion of the surface 19 and evaporated and hence the evaporation capacity is improved. On the other hand, the kerosene flowing into the groove 23 and having reached the part 23A is caused to flow upwardly along the part 23A, so that the kerosene is diffused over the surface 19 and evaporated. Consequently, the evaporation capacity is increased.
