Abstract: PURPOSE:To provide an MOS-type semiconductor device on a semiconductor substrate with a sharp impurity profile and a manufacturing method for creating an element while maintaining the profile. CONSTITUTION:When forming an MOS transistor on a substrate 1 where an impurity region with a sharp profile called a delta dope layer 6 inside it, element isolation regions are formed in MOS structures 4, 9, and 10 or an impurity layer with a sharp profile is formed after an element isolation oxide film is formed to form an MOS transistor, thus forming an MOS element without collapsing the sharp concentration distribution of a punch-through stopper and hence extremely suppressing the punch-through phenomenon while reducing the impurity concentration near a channel. Namely, channel characteristics can be drastically improved while preventing reduction in threshold voltage.

Title: Sliding member
Inventor: NAKAHARA NOBUO
IPC: F16J15/34
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To show stable performance under severe utilization conditions such as low speed, high pressure, etc. SOLUTION: A sliding member of one of a rotary circle 2 and a fixed circle 3 of a mechanical seal 1 is formed of compound material prepared by blending carbon particulates in WC (tungsten carbide). A portion of the sliding surface of the sliding member corresponding to WC is flattened, while the portion corresponding to the carbon particulates is slightly recessed compared to the flat surface. The sliding surface has unevenness composed of flat and recessed portions. Sealing fluid flowed to the sliding surface is held there by unevenness, to form liquid film on the sliding surface. The carbon particulates, having adsorption performance for sealing fluid, functions as a supply source of lubricant. Satisfactory lubricating condition can be kept on the sliding surface, so that generation of blister and abnormal abrasion can be suppressed.

Title: Liquid crystal display device
Inventor: KIMURA TADASHI
IPC: G02F1/13357
Filed: 1989-12-27
Abstract: PURPOSE:To execute bright and excellent color display, to easily manufacture a device and to prevent parallax from occuring when the device is used by constituting a light modulation part between a pair of transparent substrates having an electrode pattern inside by laminating at least two layers having a liquid crystal oriented by mutually different threshold voltages and a dichroic dystuff which show mutually different colors. CONSTITUTION:A light modulation substance 3 is constituted by laminating the layers 3a, 3b and 3c which respectively contain the dichoric dystuff, the liquid crystal and polymerized resin being as a supporting body by turns. Then, they are changed to an achromatic and transparent state from a colored state by the mutually different threshold voltages. Even when an electric field is impressed on the light modulation part, the respective layers become the colored state because only polarized light whose vibrating direction is parallel with the major axis direction of the dichroism dystuff contained in the respective layers is absorbed in the case that the electric field is not over the threshold voltages of the respective layers. Besides, when the electric field which is over the threshold voltage of one part of the layers is impressed on the light modulation part, one part of the layer becomes achromatic and transparent because the light is not absorbed only there. Thus, the bright and excellent color display is realized and the device is easily manufactured. Besides, the parallax is prevented from occurring when the device is used.

Abstract: PROBLEM TO BE SOLVED: To provide a low-cost image forming device which can read and write documents fast and electronically sort them by performing a sorting and a copying process by using only a 1st image data storage means under a condition of (number of division >= number of document images). SOLUTION: A document of a 4th page is read out by a scanner and its image while outputted on a printer is stored in a bank 1 of a memory 1. Similarly, a document of a 3rd page, a document of a 2nd page, and a document of a 1st page are similarly read by the scanner and their images while outputted on the printer are stored in a bank 4. Thus, a partial copy which is sorted is outputted. Further, the image data in the bank 1 of the memory 1 corresponding to the 4th page is transferred to the printer and outputted as an image. Similarly, the 3rd page, 2nd page, and 1st page are outputted as images. Here, if a job for next electronic sorting is generated, image data is stored from a bank 5 without reading out of the bank 1 and when a final bank (n) is reached, the image data is stored in the bank 1 next.

Abstract: PROBLEM TO BE SOLVED: To provide a carriage capable of adjusting a parallelism between a recording face and a head face and a paper gap without adjusting a support position of a guide shaft and to adjust a parallelism between a dot forming element arrangement and a conveying direction. SOLUTION: A recording head 2 is displaced in a direction perpendicular to the recording face with respect to the carriage 1 by the rotation of first bearing members 15, 16 and the recording head 2 is rotated with respect to the carriage 1 centering around a support shaft 10 by the rotation of a γ angle adjusting lever 12. As a result, the parallelism between the recording face and head face is adjusted. The position of the support shaft 10 supporting the recording head 2 is displaced in the conveying direction of a recording medium with respect to the carriage 1 by the rotation of a rotating member 14 and then the parallelism between the dot forming element arrangement and conveying direction is adjusted.  When the support shaft 10 is rotated, the recording head 2 is vertically moved with respect to the carriage 1 by virtue of the eccentric structure of the support shaft 10 so that the paper gap can be adjusted.

Filed: 1989-12-28
Abstract: PURPOSE:To obtain natural sound tone even at a high frequency by providing a sound quality adjustment means varying the frequency distribution of an audio signal in response to an effect sound addition command so as to prevent a change in the sound quality at the addition of effect sound. CONSTITUTION:A sound quality adjustment circuit 26 varies the frequency characteristic in the case of surround-off and surround-on. In this case, since a coefficient data is rewritten by the operation of high pitched sound an low pitched sound adjustment keys of a keyboard, a different coefficient data group is used by the operation of the surround-off and surround-on. Thus, the sound quality change at the surround-on is prevented and natural sound tone even at a high frequency is obtained.
