Title: High damping alloy and its production
Inventor: KONDO TETSUYA
IPC: C22C38/00
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To obtain a powder metallurgy sintered material, showing superior vibration attenuation characteristic in the temp. region near ordinary temp. and increased on plastic workability and machnability, by sintering a powder of a ferritic stainless steel having an alloy composition in which specific amount of Cr is incorporated into Fe. SOLUTION: The high damping alloy is obtained by sintering a powder of a ferritic stainless steel which has an alloy composition consisting of, by weight, 10-20% Cr and the balance Fe and also containing, if necessary, <=9% Mo, <=20% Co, and 0.5-20% Si. A powder in a modified mode of composition can be easily prepared by mixing a powder of SUS430 stainless steel and a powder of 'Triballoy (R)' in the ratio ranging from 95:5 to 70:30 by weight. This high damping alloy can be produced by sintering the powder having the above composition, rolling the resultant sintered compact, and applying sintering to it again to regulate the density of the sintered compact to a value in the range of 40-70% of true density.

Title: Shutter for camera
Inventor: MIYAUCHI OSAMU
IPC: G03B9/10
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To surely detect non-opening by utilizing a detection means of a stroboscopic trigger signal and a detection means of a film winding signal and detecting a state where the actuation of a closing driving blade is finished before the actuation of an opening blade is finished. SOLUTION: When the opening blade reaches the vicinity of an actuation finishing position, an opening switch spring 392 is separated from an opening switch original point 393 so as to obtain an off-state. An off-signal at this time is used as a trigger signal for the light emission of a stroboscope. When a closing blade reaches the vicinity of the actuation finishing position, a closing switch spring 412 comes in contact and conducts with a closing switch original point 413. The on-signal at this time is used as the film winding signal. When the spring 392 is separated from the switch original point 393 after release operation and comes in contact and conducts therewith before generating the off-signal, a CPU 432 detects these signals and gives a warning that an opening lever 311 or a closing lever 321 is not normally actuated, that is, the closing spring is actuated before the actuation of the opening spring and causes the non-opening.

Title: Production of carbamylethylstarch
Inventor: OOKITA KAZUMI
IPC: C08B31/12
Filed: 1981-06-12
Abstract: PURPOSE: To produce a carbamylethylstarch, by reacting acrylamide, in the presence of a caustic alkali, with starch which is maintained mostly in the powder form by decreasing the amount of water present in the reaction system to an extremely low level.  
     CONSTITUTION: A carbamylethylstarch is prepared by reacting starch or its derivative with acrylamide in the presence of a caustic alkali as a catalyst. This reaction is carried out under continued agitation while the starch or its derivative is maintained in the powder form by maintaining the amount of water, including the water contained initially, at 2W30pts.wt. per 100pts.wt. starch. In this reaction, it is also possible to add an organic solvent. To keep the starch in a state of slightly wet powder, it is preferred to use a small amount of an organic solvent, i.e., below 35pts.wt. per 100pts.wt. starch. As the organic solvent, one which is miscible with water, particularly a lower alcohol, e.g., methanol, is preferred.

Title: Tension setting device for roll-up or roll-back machine
Inventor: HONDA TADAHIRO
IPC: B65H26/08
Filed: 1979-07-20
Abstract: PURPOSE: To obtain a certain amount of tension for a reeled material, by determining a current, in which a coil diameter compensation current proportional to the reference coil diameter is subtracted from a current corresponding to the tension set value, to the current corresponding to the set value when an initial coil diameter is larger than the referece coil diameter.  
     CONSTITUTION: An output of a coil diameter calculating circuit 15 is stored in a memory circuit 22 and compared with an output of a reference coil diameter setter 21. For the higher output of the memory circuit 22, that is, when an initial coil diameter is larger than the reference coil diameter, a minus value proportional to the coil diameter is output from an amplifier 20. This output passes a gain control 19 and is input to an amplifier 13 in the reverse characteristic to outputs from tension setter 14 and amplifier 17. In this way, an output from the amplifier 13 is decreased by the amount in accordance with a difference between the initial coil diameter and the reference coil diameter. Thus the tension can be kept at a constant level through a pass filter.

Title: Microphone
Inventor: ENDO SATOSHI
IPC: H04R23/00
Filed: 1987-04-16
Abstract: PURPOSE:To eliminate the mixing of a noise and to prevent the occurrence of distortion of a sound by providing a light-receiving part consisting of plural photodetectors lined up, converting the positional variation of a diaphragm due to sound wave into the variation in the incidence angle of a light beam passing through a transmittable part of incident light, further, detecting the said variation in incidence angle as the light-reception width of the light-receiving part, and outputting the result in the form of a digital electric signal. CONSTITUTION:As the distance between a light source 11 and the diaphragm 12 varies, the incidence angle alpha of a beam passing through the incidence window 12a varies, and the reception-width of the light-receiving part 13 also varies. Hence the extent of the photodetector 14 to receive the light also varies. In this case, if the diaphragm 12 approaches to the light source 11, the incidence angle alpha comes larger and the light-reception width of the part 13 also comes wider. Inversely, if the diaphragm 12 goes farther from the light source 11, the incidence angle alpha comes smaller, and the light-reception width of the part 13 comes narrower. The lined-up photodetectors 14 in the light-receiving part 13 detects the light-reception width, and count up the number of the elements that receives light, thereby converts the light to a digital electric signal to be outputted. Therefore, no mixing of noise occurs during transmission by other equipments, furthermore, since amplifier is not needed, no distortion other than that occurring in the microphone itself will occur.

Abstract: PURPOSE:To improve the detection rate for nonsoldering of the surface mounted component and to automate inspection by supplying heat from a contact or to a pattern connected to the surface mounted component on a printed board and measuring the temperature of the lead part of the surface mounted component by a thermoviewer. CONSTITUTION:The surface-mounted component 102 mounted on the printed board 106 is fixed by a lead terminal 103, the pattern 105, and solder 104. When the heat of a heat generating body 108 is supplied to the pattern 105 from the contact 107, this heat is conducted to the lead terminal 103 through the pattern 105 and solder 104 and the temperature of the lead terminal 103 rises. Therefore, the temperature of the lead terminal 103 is measured by the thermoviewer 101 and then the heat which is conducted to the pattern 105 is not conducted sufficiently to the lead terminal 103 through the solder 104 is case of nonsoldering, so the temperature rise of the lead terminal is smaller than when soldering is excellent.
