Title: Image forming element
Inventor: SUGIMURA HIROSHI
IPC: B41J2/475
Filed: 1988-09-16
Abstract: PURPOSE:To simplify and miniaturize an optical printer and to increase the resolving power and area of a printing head by forming the title element by interposing a photoconductor and a heating resistor between a pair of electrodes in a laminated state and constituting at least the electrode on the side of the photoconductor layer of a light pervious electrode. CONSTITUTION:Since mechanical strength is inferior when only an element is used, a transparent base 6 is used as a support and a transparent electrode layer 1 is formed thereon and a photoconductor layer 2 is formed on said electrode layer 1 while a heating resistor layer 3 consisting of a large number of heating resistors 3A separated by insulators 3B are formed on said layer 2 and an electrode layer 4 is further formed thereon. When constant voltage is applied between the transparent electrode 1 and the electrode layer 4 and the element is irradiated with light on the side of the transparent substrate, the conductivity of the photoconductor layer rises at the part irradiated with light of the element and a current flows to the heating resistor layer 3 to generate heat. The thermal color forming body 5 arranged under the electrode layer 4 develops a color by said heat and, since the element generates no heat at a part not irradiated with light, the thermal color forming body forms no color pattern and, therefore, a developed color pattern is recorded on the thermal color forming body according to a light irradiation pattern.

Title: Semiconductor device and manufacture thereof
Inventor: KO TATSUICHI
IPC: H01L21/337
Filed: 1984-11-07
Abstract: PURPOSE:To reduce junction capacity and to make it possible to perform high speed operation, by forming a gate region, in which the side surfaces facing both source and drain regions are isolated by a wall shaped insulating film, and forming a carrier-concentration decreased region along the wall shaped insulating film in a channel region, which is contacted with the wall shaped insulating film. CONSTITUTION:A gate region 14 is isolated with respect to a source region 12 and a drain region 13 by a wall shaped insulating film 15a. Only the tip of the gate region 14 is contacted with a channel region, i.e., a low-concentration impurity region 11. Therefore, the bonding area of the gate region 14 and the channel region becomes very small in comparison with a conventional JFET. Owing to the presence of a carrier-concentration decreased region, a depletion layer is expanded. This facts also contributes to the reduction in bonding capacity. Therefore, high speed operation becomes possible.

IPC: G06F11/22
Filed: 1987-09-19
Abstract: PURPOSE:To realize the automatic production of a test pattern by actually starting a nondefective device to suck up a test pattern and giving again the ternary pin information to the device as a drive pattern to check the priority of the presence of an output mode. CONSTITUTION:A device 30 to be tested is actuated on a device 302 and the signal level of each pin is converted among H, L and intermediate levels via a comparator of a pin electronics circuit 32. This pin information is stored temporarily in a test memory 31. All pins except the one of an intermediate level are converted into a drive pattern to be applied to the device 30 and an input driver is separated for each pin for reconnection of an output comparator. In this case, the pin information obtained from the output comparator is compared with the expected value for decision whether the connection of the comparator should be kept as it is or the comparator should be changed to the input driver. This procedure is repeated until each pin of the device 30 is allocated to a correct input/output state. Thus it is possible to automatically produce a test pattern even to a device having a high function.
