Title: Injection molding method and device therefor
Inventor: SHIMODAIRA KATSUYOSHI
IPC: B29C45/70
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To perform holding and cooling of injection pressure and plasticization in a lapped manner so as to shorten a cycle time by a method wherein an injection screw is rotated by keeping a predetermined pressure in an injection pressure holding cooling process and operations of backing, stop of rotation, forward resin protrusion are repeated by plasticizing a resin so as to replenish a mold with the resin. SOLUTION: After filling of a resin is completed, a resin passage 35a is closed by a two-way valve 36 of a control device 30 in a state that a maximum holding pressure is being held. A resin pressure sensor 39 sends a detection signal of a pressure in a holding chamber 38 to a control tank 30. When the pressure is lowered below a necessary holding pressure during an injection pressure holding cooling process, a command for stopping the rotation of an injection screw 6 is outputted to a screw drive motor 26 and the two-way valve 36 is opened. Further, the injection screw 6 is advanced through the screw drive motor 26. When a resin pressure P is sufficiently raised, the two-way valve 36 is closed again and the plasticization of the resin is started again by the injection screw 6. This operation control is continued until the resin is cured to a certain degree. Accordingly, a sufficient time can be taken for the plasticization.

Title: Acoustic equipment
Inventor: ARAME YUUJI
IPC: H03G3/32
Filed: 1983-12-16
Abstract: PURPOSE:To allow a sound volume in response to a wind pressure to be listened to with a proper sound volume even when the equipment is applied to a device where the wind pressure is changed according to a mobile speed by adjusting the sound volume with an output of a small sized generator in interlocking with a mindmill rotated by the wind pressure. CONSTITUTION:When the windmill 1 is rotated by receiving a wind pressure, an output of a rectifier 3 via the small sized generator 2 is a control voltage proportional to the wind pressure and this voltage is inputted to a spund volume regulator 4. Since the sound signal from a signal source 5 is controlled automatically, a sound volume in response to the wind pressure is obtained from the output device 7 via an amplifier 6. Thus, even when the equipment is mounted on a motorcycle, the acoustic equipment which does not become difficult to hear due to the wind pressure is attained.

IPC: H04N1/04
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To eliminate image data read when an original slips by detecting a slippage of the original while the original is read. SOLUTION: The reader is started with an original placed thereon, a size of the original to be read and the read mode are set (Sly, and a reference step (line) number in conformity with the original size/mode is set (S2).

Filed: 1986-10-08
Abstract: PURPOSE:To eliminate the need to displace a photographing lens always slightly by measuring the time width of a differential signal pulse part based on a differentiation circuit to detect whether the lens is focused state or not and the degree of defocusing. CONSTITUTION:The titled device is provided with an image pickup means, the differentiation circuit 22 for differentiating a video signal outputted from the photographing means and a measuring circuit for measuring the time width of a differential signal pulse part based on the circuit 22. The differential signal of the video signal obtained from the image pickup device indicates the sharpness of a photographed object and the edge part of the object appears as the pulse-like part of the differential signal. Thereby, the time width of the pulse- like part of the differential signal is measured, whether the focused state or the defocused state is measured based on the measured value, and a defocused variable in the defocused state is detected. Consequently, focusing can be detected under the static state of the focusing lens, so that slight oscillation of the lens for the detection of focusing can be omitted.
