Title: Waterproof camera
Inventor: TAKAMURA MASASHI
IPC: G03B17/08
Filed: 1986-04-18
Abstract: PURPOSE:To realize easy handling and to move a lens barrel forth in a watertight state by forming an internal and an external air chamber in the lens barrel, and linking the internal air chamber with the internal space of a camera and the external air chamber with the outside of the camera. CONSTITUTION:When the lens barrel 2 is moved to the rearmost position to serve as a wide-angle lens, the internal space 6 of the camera is small and the capacity of the internal air chamber 5B is large. When the lens barrel 2 is drawn out to the front to enters a telephoto lens state, the camera internal space 6 becomes large and the capacity of the internal air chamber 5B decreases to allow the air in the internal air chamber 5B to move into the internal space 6 through a vent hole 3a and a vent passage 2b, so that the air pressure in the internal space 6 is held constant. Then when the lens barrel 2 is slid from the telephoto position to the wide-angle position, the internal space 6 becomes small and the capacity of the internal air chamber 5B increases to allow the air in the internal space 6 to flow in the internal chamber 5B from the vent hole 3a through the vent passage 2b. Therefore, the pressure in the camera internal space 6 is still held constant and thus the lens barrel 2 is switched between the wide-angle and telephoto states while held in the airtight state.

Title: Method for press-fixing mold
Inventor: GOIE MASATO
IPC: B22C23/00
Filed: 1990-04-05
Abstract: PURPOSE:To improve dimensional accuracy by arranging a pushing member worked with a hydraulic cylinder at the upper part of a cope and applying pressing force into a region surrounded with projecting outer shape outline to plane of cavity formed by the cope and a drag and inner edge of a flask. CONSTITUTION:Pressure fluid is supplied into the hydraulic cylinder 11 by an instruction of a CPU 17 through a control valve 14 and by working the pushing member 12, molding sand 6 in the cope 7b is pressed. In this case, the pushing member 12 as marked with hatching, i.e., the pushing member 12 approached to the cavity 8a, 8b is not worked, but only the pushing member 12 existing in the region surrounded with the projecting outer shape outline to the plane of cavity 8a, 8b and the inner edge of flask 4b is selectively worked. By this method, as the pushing force or press-fixing force is not directly applied to the cavity part, the developments of deteriorated shape and deteriorated dimension in the casting can be prevented. As a result, the dimensional accuracy is improved and finishing work of the casting is extremely facilitated.

Title: Radiation detection apparatus
Inventor: NAKAOKA HIROSHI
IPC: G01T1/24
Filed: 1995-04-17
Abstract: PURPOSE: To obtain a radiation detection apparatus by which the detection result for neutrons and the detection result for γ-rays or the like are obtained by one detector only. CONSTITUTION: A converter layer 12 which is composed of<6> LiF emits heavy charged particles such as α-rays or the like when neutrons are incident. As a result of the thickness setting of the converter layers 12, the heavy changed particles which are emitted from the converted layer 12 so as to be incident on a detector 10 have energy at a definite value or higher. The thickness of a depletion layer is set to be larger than the range of the incident heavy charged particles and to be smaller than the range of β-rays at prescribed energy which is lower than that of the incident heavy charged particles. As a result, the detector 10 absorbes energy wholly, it outputs detection pulses at a definite level or higher, and it outputs only detection pulses at a definite leverl or lower regarding incident γ-rays or the like.  Consequently, when the output pulses of the detector 10 are pulse-height-discriminated, a detection result regarding the neutrons and a detection result regarding the γ-rays can be obtained simultaneously.

Filed: 1992-04-10
Abstract: PURPOSE:To maintain stable cleaning performance even in a low-temperature environment by providing an image forming device with a heater for an image carrier and a cleaning blade which removes residual toner. CONSTITUTION:The heater 37 is arranged in a back-up roller 35 arranged opposite to the cleaning blade 22-2 with an intermediate transfer belt 19 between them, and efficiently heats an abutting part between the cleaning blade 22-2 and the intermediate transfer belt 19. Additionally, the intermediate transfer belt 19 is provided with a temperature sensor 36 for detecting the surface temperature, which is arranged on the downstream side of the cleaning blade 22-2 in the direction in which the intermediate transfer belt 19 moves. In the case of a low-temperature environment, the heater 37 is turned on to heat the intermediate transfer belt 19. Therefore, the temperature of the belt and the temperature of the blade become almost equal since the heater 37 directly heats it by holding the intermediate transfer belt 19 between them.

Title: One-shot multivibrator
Inventor: DAIMON TERUMI
IPC: H03K3/023
Filed: 1984-05-09
Abstract: PURPOSE:To attain ease of MIC by grounding one terminal of a capacitor, using one MIC.OSM (one-shot multivibrator) connecting terminal so as to detect the time when the other terminal of the capacitor is charged up to a prescribed voltage thereby avoiding a negative potential from being impressed to an MIC circuit. CONSTITUTION:One terminal of a capacitor RC2 for deciding OSM time is grounded and the other terminal is connected to a connecting terminal B of the MIC. Suppose that an input voltage Vin is a rectangular wave. As soon as an NPN transistor (Tr) T116 is switched off, the capacitor C2 is charged by a prescribed voltage source V4. A voltage VB at the terminal B is compared with a constant voltage V5 by a comparator CO1, and the moment the former reaches a V5 voltage, the T116 is switched on, a charge in the C2 is drawn and a time Lo until the VB reaches the voltage V5 or below is attained. On the other hand, a T117 is synchronized with on-off of the T116, turned on just before the output of the CO1 goes to a high level and turned off as soon as the charging of the C2 is started. Thus, an apparent output of the CO1 goes to a high level for a prescribed time only until the level of the capacitor C2 reaches the voltage V5 from 0V and a constant time pulse is obtained.
