Abstract: PURPOSE:To improve the efficiency of a compression mechanism and eliminate insufficient lubrication in a wide range of operation conditions by returning a sucked refrigerant to the compression mechanism nearly directly in the low pressure type wherein the compression mechanism is arranged at an upper level and the electric motor thereof at a lower level. CONSTITUTION:A refrigerant sucked through a suction pipe 17 arrests lube oil and cooling liquid with a wire mesh 19 so fitted as to cover an opening 18 toward the inside o the lower enclosed vessel 1 of the suction pipe 17. After the lube oil and the cooling liquid are dropped down on a stator 4 via an open part 23, only a refrigerant gas is introduced to the suction port 22 of a compression mechanism 2 via a suction passage enclosure 21. And the refrigerant gas within the compression mechanism 2 is compressed via a suction chamber 24, a compression chamber 9 and a delivery port 25, and then discharged from a delivery port 27. On the other hand, lube oil in a lube oil sump 28 at the bottom of the lower enclosed vessel 1 is sucked by a pump 29 and fed to the compression mechanism 2 via the oil feed hole 30 of a crankshaft 6. Thereafter, the lube oil is returned to the lube oil pump 28 from a discharge port 31 via the stator 4 and a communication passage 32 between both ends thereof.

Title: Mechanism for preventing forward falling of continuous folded paper
Inventor: TAKAYASU TAKURO
IPC: B41J15/04
Filed: 1989-07-13
Abstract: PURPOSE:To prevent printing shift and to facilitate the cutting of paper by constituting a guide mechanism feeding paper after printing rearwardly while preventing the falling thereof on this side in an openable and closable manner. CONSTITUTION:The continuous folded paper forward falling preventing mechanism arranged to the discharge route of paper 4 is constituted by mounting an acrylic plate 3 as a guide mechanism and an upper plate 2. Since the paper 4 after printing is sent so as to pass under the acrylic plate 3, if the paper 4 is ready to fall forwardly, said paper 4 is brought into contact with the acrylic plate 3. As mentioned above, the paper can be automatically fed rearwardly while the forward falling thereof is prevented. Further, since the acrylic plate 3 is mounted to a lower plate 1 by a hinge through the upper plate so as to be freely made openable and closable, the cutting of the paper 4 is easily performed.

Title: Motor-driven tool
Inventor: HASHIMOTO KOICHI
IPC: B23B45/16
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To miniaturize a tool main body by miniaturizing a spring that is necessary in terms of functions. SOLUTION: A drill driver has a clamping torque adjustment mechanism. A sliding torque setting spring 42 of the clamping torque adjustment mechanism is formed by winding a corrugated rectangular wire into a number of turns in a cylindrical shape. Since the spring that can provide high load although being small in diametrical and axial sizes as compared with coil springs and coned disc springs is used, the drill driver with the required load setting can be obtained while keeping the tool small.

Title: Thin film magnetic head
Inventor: NISHIYAMA TOGO
IPC: G11B5/31
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To manufacture a thin film magnetic head having a track width excellent in precision. SOLUTION: Upper-side cores opposite a lower-side core 72 with a magnetic gap 76 between are formed in two stages to constitute a two-layer structure. As a result, a track width TWA is determined with the width of the gap side of a a first magnetic film 78. The film thickness of the first magnetic film 78 is thin, the film is machined with high precision. Consequently, the precision of the track width is also enhanced. Moreover, since the machining precision is not required for a second magnetic film 84, the thickness of the film 84 may be made thicker. Thus, magnetic reluctance can be reduced by increasing areas as the whole of the upper-side cores and the recording and reproduction efficiency is improved.

Title: Digital signal encoding method
Inventor: SAGATA ATSUSHI
IPC: H04N19/50
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To obtain a digital signal encoding method for improving encoding efficiency by reducing a code quantity for quantization width as much as possible by not including a code word indicating that the quantization width of an encoded object small unit varies from its last value in encoded data. SOLUTION: When quantization width is described by small units in encoded data, the encoding efficiency becomes inferior, so a moving picture encoding system (MPEG-1) describes a code word indicating variation in quantization width in the encoded data only when the quantization width varies and describes the value of new quantization width only when the code word is present. When a method which does not include the quantization width in the encoded data is applied, the code word indicating the variation of the quantization width is eliminated in the encoding data, thereby making the encoding quantity smaller. Namely, the code word of the value of the quantization width is eliminated and the code indicating the variation in the value of the quantization width is deleted to improve the encoding efficiency.

Abstract: PURPOSE:To obtain an image output having a less visually odd feel by suppressing the influence of discrete dots in a highlight part where the discrete dots appear and further improving the gradation characteristics of the highlight part. CONSTITUTION:The threshold values are set at 0, 41, 127, 255 by sorting the values of input density signals from 0 to 255 to 4 stages.
