Abstract: PURPOSE: To provide functions of an eating chair, a study chair, and a rocking chair by combining components such as two main frame plates, a backrest plate, two seat plates, two operating rods, a study plate, a tread, and the like. CONSTITUTION: When a new three-way chair shows an upright state, an infant can sit on a chair formed by its backrest plate 2 and a chair 3 and can use it as an eating chair by resting feet on an upper operating rod 4 and a tread 8. If the chair is used in an inverted position with an arched curved surface 11 pointed up and a recessed surface 12 down, when an infant sits on a chair formed between an auxiliary seat 6 and a seat plate 3, the three-way chair can be used as a study table for reading and writing by the installation or a study desk 7. In another application, when the chair is held in an inverted position with the recessed surface 12 facing up and the arched curved surface 11 facing down and, when an infant sits on the chair, its lower operating rod 5 is controlled and feet are put on the back surface of the study desk 7 to step on it.  By the action of moving the chair up and down following an arched line which the arched curved surface 11 shows, the chair can be used as a rocking chair.

IPC: D05B69/36
Filed: 1989-08-04
Abstract: PURPOSE:To completely prevent a mode from being overlapped with the other operation mode when a thread is cut by providing an order to ignore a signal from a switch for high-speed sewing until thread cutting operation is finished by a signal from a thread cutting switch. CONSTITUTION:A microcomputer MC is operated in synchronism with a CLOCK which has a fixed time period. For example, when a switch TSW for thread cutting is turned on at a t9, a CPU reads the signal of the TSW at a t10, in which the CLOCK goes to be an H level. Then, simultaneously with the operation of a thread cutting device TRIMMER, a driving signal DRIVE is outputted and a sewing machine shaft is revolved at a low speed. Then, the thread cutting is executed. When a needle goes to an upper position at a t11, and an upper position signal UP and the CLOCK go to be the R level, the driving signal and a thread cutting signal are made L level and a brake BRAKE is made H level until a t13 and a thread wiping WIPPER is made H level until a t12. Then, a thread is wiped.

Abstract: PURPOSE:To prevent the end of a silver electrode conductor layer from migrating by coating the end of the layer exposed on the side of a sintered laminate with a thin film of metal which exhibits smaller migration characteristic than silver. CONSTITUTION:Powder of organic binder is mixed in powder of polycomponent solid solution ceramic having perovskite crystal structure to form a green sheet, silver paste is coated by printing thereon, 60-80 layers are laminated, sintered at high temperature to form a sintered laminate.

Abstract: PURPOSE:To obtain a picture with high quality and reproducibility by designating a location of a picture element interleaved or added in plural picture elements in response to a random number generated by a random number generating means so as to attain picture element density convention without causing deterioration in the picture even in case of a dither picture. CONSTITUTION:At the time of interleaving one picture element per each 4 picture elements for example, a random pulse RP is generated at its indefinite position for 4 clocks from a random number generating circuit 21, an interleaved latch clock LCK' is outputted from a gate circuit 22 and fed to a latch circuit 4. Thus, the binary picture data DS outputted from a binarization circuit 3 is latched by the circuit 4, then the picture element is interleaved corresponding to the clock LCK' and the data DS is interleaved by each 4 picture elements. Thus, at the time of recording the picture data LDS' interleaved in this way by a line memory 6, the dither pattern is changed irregularly and no longitudinal stripe pattern noise is caused in the reproduced picture. That is, the deterioration in the picture quality is suppressed and the reproduced picture with high quality and reproducibility is obtained.

Filed: 1991-07-19
Abstract: PURPOSE:To mix an adhesive simply and efficiently by employing a technique by which to mix a prepolymer or a polymer having a reactive group which performs the same operation in a specified number of times using a difference between their specific gravities. CONSTITUTION:A two-liquid container consists of the first container with an extraction orifice where a prepolymer or a polymer having a reactive group is stored and the second container where a liquid crosslinking agent is stored, as an attachment to the former. The second container is rammed through by a bar with a pointed tip so that the prepolymer or polymer having a reactive group is allowed to come in contact with the crosslinking agent. In addition, the second container is maintained in an air-tight state with the bar and the two-liquid container is turned upside down. Further, the second container is left stationary as it is to allow the materials to be mixed by a difference in their respective specific gravity. After that, the two-liquid container is again turned upside down and the same operation is repeated. Thus an adhesive can be prepared easily without troublesome operation.

Title: Shift controller
Inventor: HOTTA SHIGEO
IPC: G05B19/4103
Filed: 1987-08-17
Abstract: PURPOSE:To shorten both the processing time and the working time by neglecting plural command positions which are taught almost adjacently to a straight line and carrying out the linear interpolation just with a single straight line. CONSTITUTION:The position data are successively read out of a data memory A by a straight line arithmetic means C and a straight line set between the present position and a read-out command position. A deviation arithmetic means D outputs the deviation between said straight line and a commanded position on an action locus set in the middle of the straight line. When the obtained deviation is kept within a fixed allowable range, the commanded position is neglected out of the linear interpolation. Then a straight line set between the following separated commanded positions is operated against the present position in addition to the present position. In case the deviation between said operated straight line and the commanded position set in the middle of the straight line is not kept within a fixed allowable range, the linear interpolation is applied to a straight line set between the present position and the commanded position out of the allowable range. Thus the shift is carried out along said straight line. As a result, the working speed is improved for a robot, a machine tool, etc.
