Title: Device for indicating elapsed time
Inventor: MINOWA SHIYUUJI
IPC: G04F13/00
Filed: 1988-09-27
Abstract: PURPOSE:To allow the easy recognition of the lapse of time from a change in color by housing the laminate of a volatile liquid holding layer which contains a volatile liquid to exhibit high light transparency into a container having a freely openable/closable aperture and evaporating the liquid. CONSTITUTION:This device is constituted of the laminate 3 formed by laminating the volatile liquid holding layer 2 on an opaque base layer, the aperture 4 which evaporates the volatile liquid from the volatile liquid holding layer 2 at the controlled speed and a door 5 for starting the evaporation of the volatile liquid. This volatile liquid holding layer 2 has the property to irregularly reflect at least the external light on the surface thereof at the time of the layer 2 not contain volatile liquid and has the property that the transparency of light increases and the color of the opaque base layer 1 is visible at least partly through this layer once the volatile liquid holding layer contains liquid. A user is allowed to visually recognize the lapse of the time from the start of the evaporation of the volatile liquid on the volatile liquid holding layer 2 before the volatile liquid is substantially absent (dried) in the volatile liquid holding layer 2 as a change in the color of the indicating surface.

Title: Manufacture of thin film transistor matrix
Inventor: ENDO TETSURO
IPC: H01L29/786
Filed: 1987-09-24
Abstract: PURPOSE:To reduce noise at the time of driving a panel, by decreasing parasitic capacitance caused by overlapping of a gate electrode and a source electrode. CONSTITUTION:A source electrode S, a picture element electrode E unified in a body with it, a drain electrode D and a bus line SD connected to it are formed by using a transparent conducting film 12. Patterns except the source electrode S and the drain electrode D are covered with an opaque film 14, and thereon an transparent conducting film 18 is formed. Thereon a positive type resist film 19 is spread, and back-exposure is performed to expose the transparent parts of the source electrode S and the drain electrode D to light. Next, the light-exposure of the above resist film 19 is performed from the surface side by using a mask. Since the resist is positive type, the exposed part is eliminated by developing, and the part not exposed is left. A gate electrode G is formed by using the resist film 19 self-aligned with the drain electrode D and the source electrode S as a mask. Therefore, a parasitic capacitance of gate source is remarkably decreased, and noise at the time of driving a panel is reduced.

Title: Dew detecting apparatus
Inventor: FUKAI TOSHIHIKO
IPC: G11B15/00
Filed: 1990-09-10
Abstract: PURPOSE:To positively detect the formation of dew in a cylinder by providing a humidity sensor to a spherical regenerator fixed to an insulating plate. CONSTITUTION:A humidity sensor 1 which changes its resistance value by the humidity of the surface thereof is fixed to a flat part on the surface of a spherical regenerator 2. The regenerator 2 is fixed to an insulating plate 3 at the other flat part. The regenerator 2 is formed of, for example, aluminum allay, and the insulating plate 3 is made of material with a small thermal conductivity, e.g. synthetic resin. The regenerator made of metal or the like, and having a large thermal capacity is formed to have a small surface area into a sphere, and therefore the regenerator transfers less heat to the neighborhood. Moreover, since the regenerator is held by the insulating plate 3, the thermal conduction to a main body of the VTR is kept small. The cylinder is maintained approximately at the same temperature as the regenerator. Accordingly, the humidity sensor fixed to the regenerator forms drops of dew approximately at the same time with the cylinder, so that the formation of the dew can be quickly detected.

Filed: 1987-09-25
Abstract: PURPOSE:To prevent the damage of the glass surface of an original platen by controlling a reciplocating means so that originals are held down by means of an original cover roller in synchronization with the exposure and movement of an exposing means. CONSTITUTION:A controller 10 outputs drive signals to the driving part of a light lamp 50. At that time, the controller 10 determines the distance that the lighting lamp 50 moves to the right with the aid of detecting signals from a size detector 65. According to the size of the original 36, the controller 10 controls the driving time of a driving motor 20. Moreover, the controller 10 outputs the driving signals to the moving motor 65 of the light lamp 50, and simultaneously outputs the driving signals to a presser motor 25 in synchronization with the driving part of the lighting lamp 50. Thus, the lighting lamp 50 irradiates the original 36 conveyed by the rotation of a cover sheet 4, and the original is copied in an original position P while it is pressed by the cover roller 6. Therefore the copying accuracy is improved, and the damage of the original platen is minimized.
