Title: Direct memory access controller
Inventor: YOSHIDA ATSUSHI
IPC: G06F13/28
Filed: 1987-12-02
Abstract: PURPOSE:To transfer all data, and also, to eliminate the need of a transfer data number counter by transferring the data when an untransferred data remains behind in a data latch buffer, when an input/output port has transmitted the transfer end to a CPU. CONSTITUTION:When the data are brought to direct memory access (DMA) transfer from an input/output port 12 to a memory 13, a signal outputted at the time of the end of the DMA transfer from the input/output port 12 to a CPU 14 for managing a DMA controller 41 is utilized, and when this signal has been outputted from the input/output port 12, when the data from the input/ output port 12 to be transferred to the memory 13 remains behind in a data latch buffer, this data is transferred to the memory 13. In such a way, a transfer data counter is eliminated, the cost can be reduced, and also, even in case width of data buses of the memory and the input/output port is different, the DMA transfer can be operated normally.

Title: Thermal transfer printer
Inventor: TAKAHASHI KIYOSHI
IPC: B41J2/355
Filed: 1988-11-30
Abstract: PURPOSE:To obtain a sharp printing output without being affected by the other adjacent heating elements by a method wherein according to the number of heating elements in an electric conduction to the heating elements of a printing head three types of electric currents are selectively passed through each of the heating elements. CONSTITUTION:A printing head consists of a plurality of heating elements T1-Tn. The heating element T1 is electrically conducted by turning ON a transistor Q1 with a signal outputted from a drive circuit DRV1. On the other hand, if either one of signals from the drive circuits DRV1 and DRV2 is ON, an output of a gate circuit Ga1 becomes 'high level', a transistor Qa1 is turned ON, and an electric current from a printing head power source VH flows through both the transistor Qa1 and a resistance Ra1. With the change-over of an electric current flow path, the amount of electric current in an electric conduction to either one of heating elements T1 and T2 is controlled to be larger than that in an electric conduction synchronous to both of them.

Title: Vapor phase epitaxy
Inventor: TOKUDA HIROKUNI
IPC: C30B25/02
Filed: 1986-12-22
Abstract: PURPOSE:To obtain an epitaxial crystal of high quality, by carrying out growth under different pressure depending on the crystal quality required in each growth layer, using a hydrogenated product of group V element and organometallic compound of group III element. CONSTITUTION:GaAs substrate 114 is installed in a prescribed position and growth of andope GaAs layer is applied. At the time, pressure in a reaction tube 111 is set to about 500 torr by carrying out the exhaust in the reaction tube 111 through a route A. In this process, growth rate is relatively quick and about 0.05mu/min and GAs layer of high purity can be grown, since an inner pressure of the reaction tube 111 is close to ordinary pressure. Then after passing for about 20min, the three way valve 12 is operated and exhaust route is changed to a route B. By this operation, an inner pressure of the reactive tube is reduced to about 50 torr and the growth rate is rapidly reduced to about 0.01mu/min. Then when the pressure attains constant state, Al(CH3)3 and SiH4 are fed into the reactive tube and growth of n type AlGaAs layer is carried out. After the prescribed time is passed, the feed of Al(CH3)3 is stopped and n type GaAs layer is grown for the prescribed time to complete the growth.

Title: Recording device
Inventor: OKUBO AKIO
IPC: B65H19/12
Filed: 1986-12-22
Abstract: PURPOSE:To simplify operation of a user, by a method wherein recording sheet conveyance passages are independently formed to two sheets in roll, and by detecting that the respective conveyance passages are released, initial setting of only set recording sheets is effected. CONSTITUTION:Two separately set sheets 2 and 3 in roll have their respective independent conveyance passages. Thus, when either the sheet in roll 2 or 3 is replaced or jam processing is effected thereon, even if a conveyance passage for the sheet 2 or 3 is released, the other conveyance passage is left closed. With a given switch made by detecting the recording sheet 2 or 3 form whether the conveyance passage is released or not, initial setting is made only on the set recording sheet 2 or 3. This constitution enables simplification of operation of a user.

Title: Production of supporting body for photographic printing paper
Inventor: MIYAMA MASAO
IPC: G03C1/775
Filed: 1987-11-30
Abstract: PURPOSE:To prevent the generation of slime, and to obviate stains and holes on the title body by incorporating alpha-chlorobenzaldoxim acetate in a head box slurry in an amount of 0.1-50ppm based on the amount of the head box slurry. CONSTITUTION:The alpha-chlorobenzaldoxim acetate is incorporated in the head box slurry to prevent the generation of the slime in the producing step of a base paper usable for a supporting body of a photographic printing paper. The suitable addition amount of a slime controlling agent as mentioned above is in the range of 0.1-50ppm based on the head box slurry. When the addition amount is less than 0.1ppm, the effect of the slime controlling agent is very little, the faults such as a web break, stains and holes, etc. of the base paper are generated, resulting in the undesirable lowering of quality and productivity of the supporting body. On the other hand, when the addition amount exceeds 50ppm, the effect of the slime controlling agent is not almost increased while the undesirable, cost up and the adverse influence to a photographic emulsion is caused. Thus, the generation of the slime is controlled, and the quality and the productivity of the base paper are improved.

Abstract: PURPOSE:To evaluate the toughness of a coating film within a short time by bringing an indenter into contact with a test piece having a coating film formed on the surface, moving the test piece in one direction, adding a continuously increased load to the indenter, and detecting the elastic wave at the time of breaking the coating. CONSTITUTION:An indenter is brought into contact with a test piece (a) having a coating on a thick film surface, the test piece (a) is moved in one direction, a continuously increased load is added to the indenter 3 to detect the elastic wave at the time of breaking the coat by an AE sensor 6, and the energy of the elastic wave at the time of breaking the coating is measured by an AE signal measuring device 11. The signal form the measuring device 11 is given to a computer 13 and analyzed there. As the elastic wave energy, the square of the amplitude of the elastic wave is measured, and the value (E/N) obtained by dividing the total of the squares of the elastic wave amplitudes by the generating number of elastic waves is used as a scale of toughness. The corresponding relation of a toughness value determined by indenter pressing method with the E/N value is examined to form an analytical curve, whereby the toughness of a sample unknown in toughness value can be directly obtained from the energy of the elastic wave at the time of breaking the coating film.
