Patent JP-S6118564-A (JP)
Title: Power steering unit
Inventor: AKAIWA MICHIROU
IPC: B62D5/08
Filed: 1984-07-04
Abstract: PURPOSE:To prevent occurrence of fluid noise by providing a variable throttle mechanism for increasing the back pressure of working oil in a power steering unit while interlocking with a hydraulic control valve. CONSTITUTION:Upon rotary operation of a steering wheel to rotate a stab shaft 2 in predetermined direction, to the left for example, a hydraulic control valve 6A will move to the left thus to move a throttle valve 23 synchronously in a valve containing hole 12. Consequently, predetermined differential hydraulic pressure is produced between two operating chambers 9, 10 to move the piston to the left thus to assist motion of a steering member 11 and to control steering of wheel. The throttle valve 23 will gradually choke the exhaust control orifices 26a, 26b thus to gradually increase the back pressure of working oil to be discharged selectively from said chambers 9, 10 through hydraulic exhaust sections 6b, 6b. Consequently, the differential pressure across said sections 6b, 6b can be reduced to prevent occurrence of fluid noise.

Title: Estimating method for halftone picture of dither picture
Inventor: HIRATSUKA SEIICHIRO
IPC: H04N1/40
Filed: 1986-06-14
Abstract: PURPOSE:To excellently restore a picture edge part into a halftone picture by estimating the halftone picture so that a scanning opening including an estimate picture does not come into contact with the picture edge whose density is changed obruptly. CONSTITUTION:Plural scanning openings including an estimate picture region are prepared and openings whose estimate picture element is possibly close to the center of a dither picture (e.g., D11. D12) are selected among scanning openings not in contact with the edge. Then the matrix buried by the estimated halftone picture and the dither matrix are compared based on each picture element succeedingly. In case of the dissident pattern, the picture with less dissident picture element number has a priority and in case of the dissident picture element number to be identical, the scanning opening whose estimate picture element is close to the center of the dither picture is selected. Thus, the much difference in the level of the halftone picture is not caused in comparision with an original halftone picture.

Title: Heat accumulating appararus
Inventor: KAI JIYUNJIROU
IPC: F24S90/00
Filed: 1978-11-13
Abstract: PURPOSE:To reduce size as a whole retaining the characteristics of the water sensible heat type heat storage tank while preventing the lowering of the heat storage efficiency by compensating for the difference in the heat storage capacity required by the said tank between the cooling and heating operations. CONSTITUTION:Sodium acetate octahydrate (NaCH3COO.8H2O) is placed in a box-shaped metal container 18 as a latent heat type heat storage material. This heat storage material has a melting point of about 58 deg.C with a heat of fusion being about 60cal/g, while the heat of fusion per capacity including the container is about 7.4X 10<4>Kcal/m<3>. In total, about 0.22m<3> of the material including the container is used in the entire heat storage tank. Therefore, this heat storage tank 11 is capable of accumulating 12,000Kcal as water latent heat in the summer season by operation at 5-10 deg.C with an internal capacty of 2.62m<3>, and in the winter season, 24,000Kcal as water sensible heat at 50-60 deg.C. To this added is 16,000Kcal as heat of fusion of the sodium acetate octaacetat. Thus, in total, about 40,000Kcal can be accumulated.

Title: Original carry controller
Inventor: MORIMOTO TETSUJI
IPC: G03B27/62
Filed: 1995-05-15
Abstract: PURPOSE: To simplify a procedure when reading is restarted after the occurrence of a fault. CONSTITUTION: A state change detection section 37 senses a change in on/off of a register sensor 28. An on-timer 33 and an off-timer 35 measure an original carrying time between the register sensor 28 and a read section and expires when the time elapses. When the output of the register sensor 28 changes from an OFF to an ON state, the on-timer 33 is started and when an output of the register sensor 28 changes from an ON to an OFF state, the off-timer 35 is started. When the on-timer 33 is expired, a flag is set and when the off-timer 35 is expired, the flag is reset. The set flag indicates it that an original is at a read position and the reset flag indicates it that the original is not at the read position. A discrimination section 36 decides the state of the flag at the recovery from a fault to start the original discharge processing or the original read operation.
