Title: Digital sound recording device
Inventor: TANAKA HIDEKI
IPC: G11B5/09
Filed: 1992-10-19
Abstract: PURPOSE:To attain post-recording and to prevent the occurrence of a noise due to a boundary part by arranging a reproducing head ahead of a recording head in the running direction of the recording medium of a tape, etc. CONSTITUTION:The reproducing head 2 is arranged ahead of the recording head 3 in the running direction of the tape 1. Whether a relation between a tape running reqired time T=a/Tv for the interval (a) obtained from the arrangement interval (a) between the head 2 and the head 3 and a tape running speed Vt and lapse time information (t) outputted from a timer satisfies t>=T or not is judged. Additional sound recording is executed by the head 3 when it is judged in the relation of t>=T. At this time, sound recording data recorded additionally newly by the head 3 and the continued frame data are recorded on the tape while keeping the continuity of a frame. Thus, the occurrence of the noise is prevented since no synchronism deviation occurs when the boundary part sound recorded additionally is reproduced.

Title: Buried body surveying device
Inventor: MICHIGUCHI YOSHIHIRO
IPC: G01V3/12
Filed: 1986-12-23
Abstract: PURPOSE:To reduce an area where surveying is impossible nearby the ground surface and to increase survey depth by varying the pulse width, i.e. frequency and pulse amplitude of a radio wave oscillated by an oscillator according to observation depth. CONSTITUTION:A transmitting antenna 1 is applied with a pulse signal from the oscillator 5, which is controlled by a control signal generator 6 to vary the amplitude and pulse width of the oscillated pulse signal. A signal received by a receiving antenna 2 is amplified 7 and further sampled by a sampler 8. This sampled signal is led to a video processor 9, where the signal is made into video and displayed 10. Further, the video processor 9 inputs the position of a carriage 3 where the antennas 1 and 2 are mounted from a position detector 11. Then, the amplitude and frequency of the oscillated pulse signal are varied according to the observation depth and the pulse width is made short as the time of an observation nearby the ground surface, so the area where detection is impossible owing to ground surface reflection is reducible. Further, the attenuation of a reflected wave from a deep surveyed target can be decreased, so the survey depth can be increased.

Title: Refrigeration cycle
Inventor: NISHIDA SHIN
IPC: F25B5/02
Filed: 1993-12-08
Abstract: PURPOSE:To reduce impact sound of a water hammering phenomenon when opening and closing a solenoid valve and reduce refrigerant passing noise when the solenoid valve is opened by installing a capillary tube on the upstream side of a sub-evaporator and installing the solenoid valve to a cooling flow line between the capillary tube and the evaporator. CONSTITUTION:When a solenoid valve 31 is opened, liquefied refrigerant is supplied to a sub-evaporator 26 passing through the solenoid valve 31. During, this operation, the flow rate of the refrigerant is decreased to a small extent by a tube friction resistance of capillary tube 30 installed on the upstream side of the solenoid valve 31, thereby buffering a water hammering phenomenon. What is more, the generation of refrigerant passing through sound is also minimized. In addition, the liquefied refrigerant which has passed in the capillary tube 30 and flow through the solenoid valve 31 is partially evaporated in a process passing through the capillary tube 30. Therefore, the refrigerant flowing to the inlet of the solenoid valve 31 is turned in a two-phase state or a gas and liquid phase state. This construction makes it possible to restrain the water hammering phenomenon produced when closing the solenoid valve 31 and suspending the supply of refrigerant to the sub-evaporator 26.

Title: Base for photographic paper
Inventor: OMOTANI TSUNEHISA
IPC: C09D11/037
Filed: 1988-12-07
Abstract: PURPOSE:To obtain a base for photographic paper having high adhesion of printed picture image parts on a sheet-shaped base body to a layer coated with a polyolefin resin, and high resistance to blotting at edges by forming a printed picture image of a predetermined density on one side of the sheet- shaped base body with a water-base printing ink. CONSTITUTION:Water-base printing ink contg. a pigment consisting singly of carbon black and a binder is used for printing a base for photographic paper printed on a rear surface. Since the ink contains no white pigment nor reducer and is required only to form picture images having low density which are so low as being not detected by a mark sensor, the amt. of the carbon black pigment to be contained absolutely in the ink may be a considerably small amt. Accordingly, the amt. of the binder to be contained absolutely in order to fix the low density pigment may be also small. Such water-base printing ink has high adhesion to the sheet-shaped base body generating no choking, and a base body obtd. therefrom causes hardly blotting at the edges.

Filed: 1991-10-29
Abstract: PURPOSE:To reduce the weight of a spectrum section, that is, the multi-board type image pickup device by forming the spectral section with a dichroic mirror made of thin plates. CONSTITUTION:An object light made incident from an image pickup lens (image forming optical system) 11 is made incident on a dichroic mirror 21. Then the object light transmitted through the mirror 21 is formed on an erected image pickup element 13 and the object light reflected upward in the mirror 21 as shown in figure is formed onto a mirror image pickup element 15 arranged to a position equivalent to the element 13. The dichroic mirror 21 consists of a thin transparent plate 22 and a dichroic film 23 coated on the surface of the plate. Then the dichroic mirror 21 is supported between a couple of side support plates 24, 24 such a way that its angle is made adjustable and fixed to a lens barrel (not shown). Since a spectral section (color separate means) is formed by forming a dichroic film onto the thin plate, the weight of the spectral section is considerably made light. Furthermore, since the reflected light reflected in the dichroic mirror 21 is directly received by the mirror image pickup element 15, the full reflection mirror is not required and the weight is further reduced.

Abstract: PURPOSE:To prevent entangling of conductor and to protect the conductor and a core against damage by securing the end of an insulated wire on the inside of a stripped part, beating the stripped part, and then stripping the insulation coating off at that part. CONSTITUTION:A conductor 3 comprising a resistive wire is wound around a winding core 2 disposed around a tension member 1 and a winding type wire P applied with an insulator 4 and a sheath 5 is clasped, at an end P' thereof, by mans of a clamp 11 fixed to a frame F on the inside of a part (b) to be stripped. A presser 12 is then moved up and down, as shown by an arrow, by means of a cylinder 13 mounted on the frame F thus beating the part (b) to be stripped in cooperation with the seat 14 of the frame F. Consequently, adhesion between the conductor 3 and the insulator 4 lowers and the wire is untwisted at the end thereof. Subsequently, the part (b) is stripped off by means of a stripper cutter (a). According to the method, the conductor is prevented from entangling and the conductor and the core are protected against damage. The method is favorably employed in the termination of noise-proof resistive wire in automobile.
