Abstract: PURPOSE: To provide the cell which is high in electromotive force and energy density, and excellent in adhesion between a positive and a negative electrode by letting compounds which are adhered onto the surface of the negative electrode, and have N-F bonds, be capable of being positive electrode active material. CONSTITUTION: The uniform mixture of N-fluoropyridinium-tetrafluoroborate, LiBF4 , and 3-methylsulfonran (a weight ration is 60.4:30.6:9) is applied as positive electrode cell material 7 onto a negative electrode 2 where lithium is used as negative electrode active material, by a knife. Each nickel net 3 is inserted between a carbon plate 6 acting as a positive electrode current collector and a positive electrode can, and between the negative elctrode 2 and a negative electrode terminal formed out of stainless steel in order to assure high conductivity. The terminal 1 is combined with the can 5 via an insulating packing 4 so as to be formed into a button cell. The cell can be thereby obtained, in which adhesion between the negative electrode 2 and the compound 7 acting as positive electrode active material, is excellent, and ion conductivity and an internal resistance are enhanced.

Title: Controller for magnetic recording and reproducing device
Inventor: SAITO KENJI
IPC: G11B15/087
Filed: 1989-10-19
Abstract: PURPOSE:To make the magnetic recording and reproducing device broadcastable as a business VTR and a broadcasting VTR by one specific shaped (CUE signal) by reproducing the device (VTR) in specific directions corresponding to outputs of 1st-3rd command signals respectively. CONSTITUTION:The VTR 5 is reproduced by a program searching command (a), and the CUE signal from the VTR 5 is detected to make the VTR 5 travel reversely by a tape length corresponding to an amt. of 5 sec in the reverse direction, and after a given period of time, the VTR 5 is stopped. When READY command (b) is received 15 sec before starting broadcasting, the VTR 5 is operated to start reproducing. Then, when the CUE signal from the VTR 5 is detected, the VTR 5 is brought under the pausing state. When START command (c) is received 3 sec before broadcasting, the VTR 5 is operated to start reproducing again. By this method, even when the business VTR is used as the broadcasting VTR, broadcasting can be performed without involving any modification of the device, and without recording two kinds of CUE signals either.

IPC: G11C16/02
Filed: 1984-12-26
Abstract: PURPOSE:To decrease greatly the data writing time to a large capacity ROM containing many memory addresses by providing a latch circuit within the ROM to hold temporarily the write data. CONSTITUTION:An EEP-ROM contains a storage mat MX, a Y decoder 1, an X decoder 2, power-down/program logic part 3, an output buffer part 4, a Y gate circuit 5, etc. The lower five bits A0-A4 of the address data are advanced every bit, and the write data D0 is replaced. Then latch circuits F1-Fm set on Y selection rows Y1-Ym latch the write data equal to a line respectively. A program terminal PGM is set at L and the data equal to a row and held by those latch circuits are written simultaneously to memory cells M11-M1m set on the corresponding column. The latch time of the latch circuit can be extremely decreased compared with the necessary writing time. Thus it is possible complete the writing of data equal to a row just in a single time of writing.

Title: Lumber having smoked broken cellular-pore-cell
Inventor: ANDO MINORU
IPC: F26B9/06
Filed: 1994-10-12
Abstract: PURPOSE: To facilitate drying lumber readily by breaking completely or partially cellular pores existing in lumber cells in order to form interstices among the cells of lumber, and at a lumber drying process performed thereafter, allowing moisture contained in the lumber forming cells to come out easily. CONSTITUTION: By opening the rear door of a processing chamber 27, latticed lumber 16 piled up on a truck 19 is housed therein and then the door is closed, and while operating a ventilating fan 13, woody fuel is fired so as to produce lumber gas. Lumber gas is passed through air conduits 6 and the air holes 20 of a processing chamber 27 and stays in the processing furnace for smoking lumber. Watching a gas sensor inserted in the furnace, the replenishment of woody fuel is effected by the opening and closing operation of an air intake 1 for allowing the density of lumber gas to be controlled within a desired range in the processing chamber.  In this manner, since heat accumulation is made into high density lava 23 or the like and thus the process is promoted by lumber gas, smoking unevenness by lumber gas can be prevented, and the decrease of density of lumber gas in the processing chamber can be kept minimum without the necessity of replenishing fuel at night.

Filed: 1986-11-17
Abstract: PURPOSE:To enhance heat resistance, by constituting the title electrode of a seal for sealing the first hollow pipe and preventing the leakage of an internal solution to the outside and the second hollow pipe for covering a stem. CONSTITUTION:The ion selective responsive film 2 fitted to a hollow pipe 1 so as to seal one end thereof is immersed in a high temp. liquid to be examined to measure the concn. of the specific ion in the liquid 9 to be examined. In this case, the internal solution 3 and air 10 of the hollow pipe 1 expand by heating and, when the internal pressure of the hollow pipe 1 rises to reach the friction force between a seal 5 and a stem 6 or more, the stem 6 integrated with an electrode 4 rises and the air in a cavity 11 is discharged to the outside from a hole 8 to suppress the rising in the internal pressure of the hollow pipe 1. When the temp. of the liquid 9 to be examined is further high, the stem 6 further rises and the projection 12 provided to the lower end of the stem 6 contacts with the projection 13 of the hollow pipe 1 to stop the stem 6. By this mechanism, it is prevented that the stem 6 is separated from the hollow pipe 1 and the internal solution is released from the sealed state to change. By this method heat resistance can be enhanced.

Filed: 1984-12-27
Abstract: PURPOSE:To facilitate the mask alignment, by constructing alignment marks such that a portion in a mark region or background region provided with a polysilicon layer is composed of first and second sections having different total thicknesses, with the difference being such that their reflectivity cycles are deviated from each other when monochromatic light is applied thereto.

The graph shows the relation between a thickness of the PSG layer and a reflectivity of mark portions 12R and 12L, taking the thicknesses on the axis of abscissa and the reflectivities on the axis of ordinate. The graph is made by computer simulation on the assumption that the thickness of a resist layer is 9500Angstrom  and the wavelength is of G line of mercury (4358Angstrom ). If the difference in total thickness between the layers in the first mark section 12R and the layers in the second mark section 12L is approximately 900Angstrom , the phases of reflectivity on the G line of mercury are deviated from each other by a half wave-length.
