Title: Parallel compression type refrigerating plant
Inventor: HAYASHI SHIGERU
IPC: F04B49/00
Filed: 1981-02-12
Abstract: PURPOSE:To secure a lubricant, in the titled plant wherein the lubricant is supplied from one of compressors to the other, even when said other compressor only is in operation, by constituting such that the oil sump chamber and the upstream suction chamber of the other compressor have generally the same pressure. CONSTITUTION:In case only the first refrigerant compressor 1 is operated, the pressure in a suction chamber 103a is lower than the pressure in a suction chamber 203 and an oil sump chamber 204, and due to the pressure drop by a throttle passage 107 the pressure in the suction chamber 103b becomes lower than the  pressure in the upstream suction chamber 103a. The pressure in the oil sump  chamber 104 of the first compressor 1 becomes an intermediate value of the pressure in the downstream suction chamber 103b and the pressure in the oil  sump chamber 204, and since it becomes approximately equal to the internal  pressure of the suction chamber 103a, the supply of the lubricant from the suction chamber 103a via an oil equalizing check valve 106 to the oil sump chamber  104 would not be interfered.

IPC: G06F3/041
Filed: 1984-02-07
Abstract: PURPOSE:To eliminate difficulty of adjustment and a danger of loss of a switching function to obtain a high-operability and high-reliability input device pen by keeping the pressing state between a depressing element and a pressure sensing mechanism part well without fine adjustment with respect to the pen for input device. CONSTITUTION:If dimensions of a spring 6 itself and the other parts are so designed that the spring 6 has enough elasticity FA to support the weight of a penholder, play is not generated in a penpoint. For the purpose of setting an input detection pen pressure to FB, a load sensitivity FC of a pressure conductive rubber 2 is set to satisfy FC=FA+FB. The load sensitivity of the rubber 2 is set optionally by combining the method, where the pressure sensitivity of the rubber itself is changed by materials, and the method where a load pressure to the rubber for a load is changed by the area and the shape of the depressing element. Consequently, a number of degrees of freedom in design of the spring 6 is attained and flexibility is given to setting of the pen pressure sensitivity of the pen.

Filed: 1994-02-18
Abstract: PURPOSE:To attain adaptive coding in response to property of a picture by generating reference data of Markov model coding in a form including the result of area discrimination in response to a structural statistic quantity from a binary picture. CONSTITUTION:An area discrimination section 11 discriminates at which area a j-th noticed picture element Xi,j of a 1st line of an input picture is in existence. Picture element period data from a period arithmetic operation section 16 and an estimate density L*i,j from a change point Vi,j estimate density arithmetic operation section 15 calculated by a dispersion arithmetic operation section 14 are used. The discrimination content indicates whether an object picture element is a flat part of a picture or a contour, a part with a period of picture element or without the period. Whether or not the picture is a part with a period of picture element is immediately discriminated by an output from a period arithmetic operation section 16, then the discrimination is a major operation of the discrimination section 11. Thus, the adaptive Markov model coding is performed in response to the property of the picture, then adaptive coding in response to the property of the picture is executed.

Title: Tracking actuator for optical disk device
Inventor: TEZUKA KOICHI
IPC: G11B7/09
Filed: 1991-02-14
Abstract: PURPOSE:To miniaturize the tracking actuator while preventing an optical axis from being shifted by driving the actuator by using first and second spring members, and deciding the length and spring constant of the member when energizing the central part of a galvano mirror so that a distance ratio and the inverse ratio between a virtual axial line and each member can be respectively equal. CONSTITUTION:When an actuator 43 is driven, force F is exerted vertically to the face of a galvano mirror 42, and the 1/2 force is exerted, respectively to first and second spring members 46 and 47. Therefore, when the lengths of the respective members are defined as L1 and L2, the spring constants are defined as K1 and K2, and the distances are defined as X1 and X2, the member 46 is extended for L1a=F/(2K1) and the member 47 is extended for L2a=F/(2K2). Accordingly, the ratio between a full length L1+L1a of the member 46 and a full length L2+L2a of the member 47 is made equal to the ratio between the distances X1 and X2. Thus, the extended face of the mirror 42 is turned to pass through a virtual curve 50 at all times, the optical axis of reflected light 60 is not shifted to that of incident light 61, and a tracking control signal having no offset can be obtained.

Title: Image forming device and method for correcting deviation in position of image
Inventor: NAKAYAMA YASUNORI
IPC: G03G21/00
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of obtaining the more excellent reproduction image by correcting deviation in a position of the image more accurately, by means of preventing a recording sheet from being wasted unwittingly. SOLUTION: When a specified copying condition is set (Y of S1), the positional deviation amount 1 is determined by forming a register mark on a transfer belt (S10 to S12). Next, the positional deviation amount 2 is determined by forming the register mark oh the recording sheet (S13 and S15). A difference between the obtained positional deviation amount 1 and 2 is determined, and stored by an EEPROM (S16 and S17). When the specified copying condition is not set (N of S1), the positional deviation amount 1 is determined by forming the register mark on the transfer belt only (S20 to S22). Then, based on the difference stored by the EEPROM, the positional deviation amount 1 is corrected, and the positional deviation amount 1' is determined (S23). Based on the positional deviation amount 1' obtained in this way, correction of the image writing position is performed (S18).
