Title: Three-dimensional image input apparatus
Inventor: TANI NOBUHIRO
IPC: H04N5/355
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To simply obtain three-dimensional image information of a moving object to be measured at a low cost. SOLUTION: Photodiodes at an interval of 5 horizontal lines in a CCD of this three-dimensional image input device detects signal charges with respect to distance. Vertical transfer CCD pulses (4-phase drive pulses) S52, S53, S54, S55 are used to transfer the signal charges having been transferred to the vertical transfer section in the direction of a horizontal transmission section. While a horizontal transfer CCD pulse S50 is outputted, a vertical transfer CCD outputs pulses corresponding to 6 cycles. Thus, the signal charges by one line transferred to the horizontal transfer section are outputted to the outside of the CCD by using a horizontal transfer CCD pulse S51.

Filed: 1986-07-28
Abstract: PURPOSE:To achieve a higher corrosion resistance as well as electric insulation, by housing a thermosensitive element and a lead into a cylindrical case while the case is filled with a filler after the element and the lead are covered. CONSTITUTION:A lead 6 of a thermosensitive element 5 is formed by bending and in such a manner as to be drawn in the same direction as that of a lead 7, while the thermosensitive element 5 and the leads 6, 7 are provided with a covering 9 of powdered epoxy. Thereafter, the work thus covered is housed into a cylindrical case 4, which is filled with a filler 8. The filler 8 employs epoxy, alumina, magnesia or the like. This eliminates the existence of a fine part requiring the penetration of a molten resin thereby enabling the prevention of deterioration in the heat conductivity due to poor filling with the filler. A higher insulation as well as water resistance are achieved with an increase in the cover layer.

Title: Mixer
Inventor: OGURA TAKEISA
IPC: B01F15/04
Filed: 1987-07-17
Abstract: PURPOSE:To continuously control the mixing ratio in a pipeline with high precision and with a small amt. of solvent by controlling the flow rate of the org. solvent in a gaseous state. CONSTITUTION:The org. solvent 5 is heated in each heater 1 to a temp. higher than its b.p. to generate the vapor of the solvent 5, and the vapor is transported to a pipeline 7 by the carrier gas 6 such as gaseous nitrogen. The flow rate of the transported vapor is controlled by a mass flowmeter 2 to a specified value, and the vapor is further transported by the pipeline. The vapors of the respective solvents are mixed in a mixing pipe 3 packed with a column. The mixture is then passed through a cooler or a temp. regulator 4, cooled, and liquefied, or used as a gaseous mixture kept at a specified temp. Since the flow rate of the vapor is thus controlled, precision is enhanced, and stabilized control can be carried out because the volume of the vaporized solvent is large.

Title: Digital electronic still camera
Inventor: MISAWA MITSUFUMI
IPC: H04N5/225
Filed: 1989-07-10
Abstract: PURPOSE:To surely store a picture data before the transmission by providing a means detecting whether or not a picture data is transferred to an external device, and disabling the replacement a battery contained in a battery holder when the untransmitted data is detected. CONSTITUTION:When the pickup is finished, a photographer connects a camera to an external memory through a connector to transfer a picture data in the memory to the external memory. When all picture data are transferred, a memory control circuit outputs a reset signal to a CPU, from which a lock release signal is outputted. When a bistable plunger 54 moves to a position shown in broken lines, a lock lever 56 is made turnable against the energizing force of a spring 64, thereby opening a battery cover 50 optionally. Thus, before picture data is transferred from the memory, the photographer does not open the battery cover 50 in mistake, and the picture data before the transmission is surely stored.
