Title: Reed valve of compressor
Inventor: MUNAKATA AKIHIRO
IPC: F04B39/10
Filed: 1990-03-02
Abstract: PURPOSE:To shorten the length of a flat section for miniaturizing a compressor by providing a clearance groove on the contact surface of a plate with a reed valve plate and making the contact point of the flat section and curved surface of a valve guard become a position opposing to the clearance groove. CONSTITUTION:A reed valve plate 1 and valve guard 2 are integrally clamped and fixed to a plate 5, whose port 3 is opened, by a bolt 6. The joint point of the flat part and curved surface section of the valve guard 2 is installed at a position opposing to a clearance groove 4 through the valve plate 1. Therefore, the length l'2 of valve opening section in the range of clamping bearing generation due to the bolt 6 is generated therein can be shortened due to the existence of the clearance groove 4, and for this reason the required length e1' of the flat section of the valve guard 2 can also be shortened. Therefore, the whole of a compressor can be miniaturized.

Title: Semiconductor device
Inventor: NAKASE YASUNOBU
IPC: H03K19/08
Filed: 1987-03-03
Abstract: PURPOSE:To drive a large load capacitance at high speed without impairing the performance of a bipolar transistor and causing breakdown, by adding an element energized when a reverse bias voltage being applied between the base and the emitter of the bipolar transistor exceeds a prescribed value. CONSTITUTION:When the lowering of the emitter potential of the bipolar transistor 9 is delayed and it becomes larger by Vf than the base potential at the time of switching an output terminal 8 from a high level to a low level, a diode 13 is energized. Therefore, the electric charge of a wire connected to the output terminal 8 is also discharged by a MOS transistor 4 via the diode 13, and the maximum potential in a reverse direction to be applied between the base and the emitter of the bipolar transistor 9 is limited to the Vf, and the bipolar transistor 9 is operated normally without generating the breakdown. Also when the load capacitance of the wire connected to the output terminal 8 is large, since a part of accumulated charge is discharged by the transistor 4 via the diode 13, the change of the output terminal 8 from the high level to the low level can be accelerated.

IPC: F16F1/06
Filed: 1995-03-09
Abstract: PURPOSE: To provide a tension spring in which the hook part is difficult to slip from a through hole of an attaching part, assembling workability can be improved, and the function of a stopper is provided by making a double structure through a process of turning over the hook part. CONSTITUTION: In a tension spring 10, since a hook part 10b is turned over and a double structure is formed, the action part of tensile stress is made into a double structure, and the strength of the action part of tensile stress is improved. Therefore, the hook part 10b can be made into a structure wherein it is not easily deformed and it is difficult to slip from a through hole 31a. Since the turning-over point part is made into a tip 10a of the hook part 10b by turning over of the hook part 10b, the tip 10a is roundish, and it is easily inserted into the through hole 31a, and assembling workability can be improved.

Title: Silver halide photographic sensitive material
Inventor: HIRANO SHIGEO
IPC: G03C1/485
Filed: 1986-03-07
Abstract: PURPOSE:To obtain a direct positive photosensitive material sufficient in reversibility even in the case of using a processing solution comparatively low in pH by incorporating a specified heterocyclic quaternary ammonium salt in an emulsion layer or a hydrophilic colloidal layer. CONSTITUTION:At least one of the emulsion layers or other hydrophilic colloidal layer contains at least one of the alkynyl-substituted heterocyclic quaternary ammonium salts represented by formula I in which R<1> is an aliphatic group; R<2> is H, an aliphatic or aromatic group; Z is a nonmetallic atomic group necessary to form a 5- or 6-membered optionally substituted hetero ring on the side of the quaternary ammonium ion; and Yn is a counter ion for balancing electric charge, and n meaning a number of valence electrons is 0 or 1. The nucleating agent of formula I may be added to the hydrophilic colloidal layer adjacent to the silver halide emulsion layer, but it is, preferably, added to the silver halide emulsion layer, and it is practically useful to add it in an amount of 1X10<-7>-1X10<-2>mol per mol of silver halide.

Title: Underwater acoustic equipment
Inventor: OBATA HIDENORI
IPC: H04R1/44
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent the defective insulation of a sensor and also to prevent the vibrations of a cable from reaching the sensor by adhering the cable conductors directly to a mold member and therefore completely cutting off the water. SOLUTION: The inside/outside part of a clamp 5 including the upper outside part of a case 1 and the upper surface part of a flange 4 through the cable conductors 6a and 6b and the periphery of the lower end part of a cable 6 are molded into a single body via a mold member 7. Thus both conductors 6a and 6b are bared from the cable sheath 6c and directly adhered to the member 7 in a clamp 5. In the water, the inundation caused through the surface or the damaged parts of the sheath 6c can be prevented at an upper erected clamp part 5c by the adhesive strength. Thus a sensor 3 never sinks more and can be protected from its defective insulation caused by the water. Furthermore, the sheath 6c is not directly connected to the case 1 and the member 7 functions as a mask or damper to the cable 6. As a result, the vibrations of the cable 6 never affects the sensor 3.

Abstract: PURPOSE:To reduce a loss of aeration in heat caused by a natural draught in case of terminating operation in a heating facility such as a water heater or the like by a method wherein a multi-vane fan moving apparatus is provided in which the multi-vane fan is abutted against a front surface of a casing under a stopped condition of an electric motor and an air inlet opening is closed by a lip. CONSTITUTION:An engagement between a hub 18 at a rear part of a fan 13 and a rotary shaft 17 is made such that a pin 22 uprighted at an outer circumferential surface of a rotary shaft 17 is slidably engaged with an inclined groove 23 formed and inclined in respect to the hub 18 in its axial direction. Its inclined direction and a length of the groove are set at a position retracted and spaced apart from a front surface of a casing 12 when the fan 13 is started to rotate. In turn, when the fan terminates to rotate, the hub 18 is rotated along the rotating shaft 17 under its inertia force and advances to forcedly contacts with the front surface of the casing 12. Under such a condition as a fan 13 is forcedly contacted with the front surface of the casing 12, a lip 21 at the front surface of the fan closes the intake port 15 and shuts off the inflow of air. In turn, when the fan starts to rotate, the fan 13 is automatically removed from the front surface of the casing.

Here, when the roller 19 falls in the rotating direction of the hub stand 12 by the absorption force of the hub 15 by a magnet 13 and the friction force with a magnetic head with the rotating body, the falling of the roller 19 is regulated by a roller 20, the relative dislocation in the rotating direction with the hub stand 12 and the rotating body is prevented, and index period dislocation, rotating jitter, etc., are prevented. In such a way, positioning of the rotating body is surely and correctly attained.
