Title: Semiconductor device
Inventor: YAMADA YUTAKA
IPC: H01L21/336
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To facilitate pattern design of a high breakdown-voltage MOS transistor and also to make its pattern area small. SOLUTION: An n+ type source region 5 is surrounded by a field oxide film 3, and is adjacent to a channel stopper layer 11 at a position corresponding to the end of the film 3. In this way, an n+ type drain region 4 is positioned away from the end of the film 3 and an n-type drain region 10 is formed in the vicinity thereof, whereby a breakdown voltage between the source and drain can be made high. Further, since the region 5 is set to have the same potential as ground (0V), this will cause no breakdown voltage problem even when the region 5 is brought into contact with a channel stopper layer 11.

Title: Piston ring
Inventor: SATO YOSHINORI
IPC: F02F5/00
Filed: 1991-02-19
Abstract: PURPOSE:To reduce a cost and improve scuffing resistance during test run or running-in by dispensing with processing after flame coating to a ring outer peripheral surface in a flame coating piston ring. CONSTITUTION:A piston ring 10 has a coating layer on its outer periphery by flame coating. An outer peripheral surface roughness of a ring main body 11, being not more than 0.5mum in Rz, has a coating layer 12 whose thickness ranging between 5mum and 50mum. Instead of the coating layer 12, an axially waved coating layer 15 may be provided. When the coating layer 12 is 5mum or less in thickness, it is eliminated before proper conformatibility to a cylinder wall surface is obtained. When the coating layer 12 is more than 50mum in thickness, roughness of the flame coated surface of the coating layer 12 is increased, being apt to damage a cylinder liner surface.

Title: Speed control circuit for motor
Inventor: HIOKI TOSHIAKI
IPC: H02P29/00
Filed: 1983-03-17
Abstract: PURPOSE:To enable to preferably control a motor speed by selecting a comparison signal in response to the rotating state of the motor. CONSTITUTION:When a speed detector 7 detects that the rotating speed of a disk is largely fast, the output (e) of a comparison signal generator 17 passes gates 12, 13, 15, and is applied as a comparison signal (b) to a phase comparator 2. Since the frequency of the output (e) is higher than a reference signal (a), the phase comparator 2 outputs a signal for decelerating the rotating speed of the motor. On the other hand, when it is largely lower than the rotating speed of the disk, a comparison signal selector 11 does not select any of comparison signals (d), (e). Accordingly, a signal for accelerating the rotating speed of the motor is outputted from the comparator 2. In this manner, the motor is rotatably driven substantially near the prescribed speed.

Title: Instance data base retrieving system
Inventor: MURAKAMI SUSUMU
IPC: G06F17/30
Filed: 1990-02-28
Abstract: PURPOSE:To easily decide the data of high preference by deciding the priority of data based on the degrees of attribution and necessity and outputting the data based on the priority. CONSTITUTION:The degrees of attribution are added to data following a key word and against the data on the key word. When a data base 11 is retrieved, an input means 13 secures the key word and the degree of necessity of data against the data on the key word. A retrieving means 12 obtains the least degrees of attribution and necessity for each data key word, obtains the maximum value between the least values as a coincidence degree, obtains the maximum degrees of attribution and necessity, obtains the least value between the maximum values as a coincidence degree, and outputs the data in the order of higher coincidence degrees. Then the means 13 selects the retrieving ways of the means 12. Thus the priority of data is decided based on the degrees of attribution and necessity and the data are outputted in the order of priority. Then the data of high preference is easily decided.

Title: Control system for correction of rotational synchronization
Inventor: OTSUKI SHOHEI
IPC: G05B19/18
Filed: 1990-02-28
Abstract: PURPOSE:To attain the highly accurate rotational synchronization in a simple constitution by controlling the number of rotation of one of two rotary shafts against the other one via a differential mechanism in response to the rotational error produced between both rotary shafts. CONSTITUTION:A rotary drive shaft is connected to a rotary shaft 1, and a rotated shaft is connected to a rotary shaft 2 respectively. Both shafts 1 and 2 are connected to each other via a differential gear in a differential mechanism 10. The rotation detectors 5 and 6 detect the rotational angles of the shafts 1 and 2. Then a synchronization control means 14 detects the rotational error between both shafts 1 and 2 based on the output signals of detectors 5 and 6 and controls the mechanism 10 in order to eliminate the rotational error and to secure the synchronous rotations between both shafts 1 and 2. When a rotational error is produced between these two different shafts 1 and 2, the means 14 controls the number of rotation of the rotated shaft to the rotational frequency of the rotary drive shaft in the mechanism 10 in response to the rotational error. Thus the mechanism 10 is controlled so that the rotational error is reduced. In such a simple constitution, the highly accurate synchronous control is attained between two rotary shafts.

Title: Extending and smoothing processor of picture data
Inventor: SONOBE KENICHI
IPC: H04N1/409
Filed: 1993-02-12
Abstract: PURPOSE:To provide a extending and smoothing processor whereby the diagonal line of a graphic pattern such as a chinese character, etc., is smoothed. CONSTITUTION:Input picture data are successively stored in a 7X7 register matrix 61. A pattern detecting part 62 detects the black or white linkage pattern of a reference picture element in a picture element under consideration 61a. An extending and smoothing processing part 63 interpolates a series of the picture elements of the extension-processed picture elements under consideration by the black picture element at the time of the 1:n(n=1, 2, 3,...) black linkage pattern. At the time of the 1:n(n=1, 2, 3,...) white linkage pattern, a part of the picture element of the extension-processed picture element under consideration is erased. In result, the diagonal line is smoothed. Also the line made to be thick by smoothing can be corrected to be the thin line so that the nice- looking picture is outputted.

Title: Operation controlling method for refrigerator

IPC: F04B49/00
Filed: 1981-03-31
Abstract: PURPOSE:To enable to operate a prime mover at a highly efficient region, by designing the prime mover to be used for refrigerating operation, and changing the capacity of a compressor in case that it is used for space-cooling operation and the output of the prime mover is not sufficient for this purpose, so that a refrigerating capacity suited for the output of the prime mover can be obtained. CONSTITUTION:A screw compressor shown in the drawing is designed such that the ratio of inernal volumes can be varied by varying the length of a slide valve 5. In using the compressor for one of multiple purposes requiring a minimum driving force (for instance, production of ice), the capacity of the slide valve 5 of the compressor is set at 100% (as shown by AB in the drawing). On the other hand, in using the same for a purpose requiring a greater driving force (for instance, space-cooling), the capacity of the slide valve 5 is set at a restricted value (as shown by A' B' in the drawing), estimating the extra output (5% in general) of the maximum output of the prime mover 21. With such an arrangement, it is enabled to operate the prime mover 21 at a highly efficient region in both of the above two operations as shown in the drawing and to raise the primary energy efficiency.
