Title: High speed writing system for disk controller
Inventor: TANAKA KEISHICHIROU
IPC: G06F12/08
Filed: 1990-03-20
Abstract: PURPOSE:To suppress the data dissipation at the time of missing write to the minimum by writing back data until the previous write written in a nonvolatile memory from a host computer to a disk device, when write fails in a cache memory for executing write from the host computer. CONSTITUTION:When write fails in a cache memory 22 for executing write from a host computer 10, data until the previous write written in a nonvolatile memory 23 from the host computer 10 is written back to a direct access storage device (DASD) 11 constituted of a magnetic disk. Also, when write fails in the nonvolatile memory 23 for executing write afterward, data until the present write written in the cache memory 22 is written back to the DASD 11. Therefore, even if there are many data which are not written back but dissipated at the time of failure of write, write from the host computer 10 is enough by a single time portion. In such a way, the data dissipated at the time of missing write is suppressed to the minimum.

Abstract: PURPOSE:To eliminate needles feeding of a film ribbon by changing a cooling operation of a printing head upon an increase in the temperature of the head, based on a detection signal from a detecting means for discriminating the kind of an ink ribbon. CONSTITUTION:While a temperature not higher than a predetermined temperature is detected by a temperature sensor 21 fitted to a printing head 5, a predetermined printing operation is conducted. When a printing duty is heavy and the temperature of the head 5 exceeds the predetermined temperature, a protective operation is started. In the case of a ribbon cassette 2 for a loop form belt 1 which cassette does not have a projected part 14, a micro-switch 15 is turned OFF, so that a blind swing operation is carried out, that is, only a carriage motor 23 is driven by immediately stopping a printing operation, or a unidirectional printing operation is conducted. On the other hand, in the case of a film ribbon cassette 11 having the projected part 14, the micro-switch 15 is turned ON, so that both the printing operation of the head 5 and the driving of the carriage motor 23 are stopped to perform natural cooling of the head. Thus, needless feeding of the ribbon is obviated.

Title: Foam slush molding apparatus
Inventor: NAGASE TAKASHI
IPC: B29L22/00
Filed: 1986-03-29
Abstract: PURPOSE:To obtain a foam slush molding device, throughout which almost no temperature difference develops in hot air, by a structure wherein a hollow heat insulating body is provided along the mold surface of a slush mold and a large number of vent holes are made on the hollow heat insulating body. CONSTITUTION:Along the mold surface 10a of a slush mold 10, a hollow heat insulating body 12 is provided so as to have the predetermined space interval between the surface and the body. In addition, hot air passages 13 are formed between the hollow heat insulating body 12 and the mold surface 10a of the slush mold 10.

At the same time, on a barrier 12a, which is not opposite to the mold surface 10a, a hot air supply port 14 is opened in order to supply air therethrough. Because a large number of vent holes are made on the passage forming surface of the hollow heat insulating body as described above, hot air is uniformly spread over the whole area in the hollow heat insulating body and uniformly strikes against resin so as to heat the resin uniformly.

Title: Buffer type gas circuit breaker
Inventor: TAKAGI HIROKAZU
IPC: H01H33/16
Filed: 1989-03-27
Abstract: PURPOSE:To make the size compact and reduce a charged overvoltage by setting a charged speed of a charged resistance contact part at both movable electrodes composing a main contact in an arc extinguishing chamber more than a relative charged speed of the electrodes, and opening the charged resistance contact part only after charging the main contact. CONSTITUTION:If a charged command is given, an operation rod 36 is moved to the charging side. Pressure liquid is supplied to a liquid chamber 501b in a charged resistance contact operation cylinder 50 simultaneously, where inside a liquid chamber 501c is kept at an atmospheric pressure, and a piston 502 and an operation rod 49 are moved to the charging side at a high speed. At this time, a drive speed is set at more than twice the drive speed of a rod 36. At this time, the relative charging speed of a first movable electrode and a second movable electrode of an arc extinguishing chamber 30 is twice the drive speed of the rod 36. In the meanwhile, the operation cylinder 50 is driving the rod 49 at a higher speed than the relative speed of the first and second movable electrodes in the arc extinguishing chamber 30, so a charged resistance contact is necessarily charged prior to a main contact in the arc extinguishing chamber. An over-voltage at the time of charging can thus be restricted.

Abstract: PURPOSE:To reduce the number of obtuse angle triangles by using an average interval of dots of a dot string as the reference to control lengths of sides of a triangle mesh to be generated and moving coordinates of a nodal point to be noticed. CONSTITUTION:An average value of lengths of two sides of a part to be processed and an average value of lengths of all sides are compared with each other and a correction ratio (r) is calculated based on the comparison result in accordance with a formula I, and the average value of lengths of two sides is multiplied by the correction ratio (r) to generate triangle elements and sides of triangle elements are averaged. Coordinates Pi of a nodal point (i) and indicated by a formula II are moved based on distances from nodal points adjacent to the nodal point (i) and coordinates of respective nodal points to form a mesh. In these formulas, (n), hi, Ni, Pj, and Hj are the total number of dots of the dot string indicating an area where triangular areas should be generated, the distance between points (i) and i-1, the number of nodal points adjacent to the nodal point (i), coordinates of a nodal point (j), and the distance between nodal point (i) and (j) respectively. Thus, the occurrence of an obtuse angle triangle in the triangular mesh is suppressed.

Inventor: TOYAMA HIROSHI
IPC: H04N5/66
Filed: 1994-04-11
Abstract: PURPOSE:To enable multilevel display with a low electric power. CONSTITUTION:A reference voltage complied with the polarity of an AC signal S4 is selected from among plural reference voltages and outputted, the selected reference voltage is applied on a data signal line 2-i only in a period tw and the potential of the data signal line 2-i is made equal to the reference voltage only in the period tw. Since the data signal line 2-i after the termination of the period two becomes a high impedance state, the voltage is held by means of electric charge stored in a wiring capacitor of the data signal line 2-i. A lamp driving voltage is applied on all wiring capacitors of the data signal line 2-i and the voltage of the data signal line 2-i in the high impedance state causes the equivalent voltage change following up the waveform of the lamp driving voltage generated by a scanning signal circuit 60 and a common electrode driving circuit 100. The potential difference between the voltage of the data signal line 2-i just after the termination of the period tw and the voltage of a common electrode 8 becomes a writing voltage in a liquid crystal cell.
