Title: Hard alloy for impact resistant tool
Inventor: KODAMA MITSUO
IPC: C22C29/08
Filed: 1981-10-02
Abstract: PURPOSE:To obtain a sintered hard alloy for an impact resistant tool with superior impact and wear resistances by sintering a hard phase contg. Mo-W carbide as a principal component with a binding phase of an Fe group metal. CONSTITUTION:Particles of simple hexagonal system (Mo,W)C or a mixture of (Mo,W)C with WC as a hard phase are sintered with 3-60wt% Fe group metal such as Co as a binding phase. The percentages of Mo and W in the hard phase are 5-95% Mo and 95-5% W, and the ratio of (Mo,W)C/WC is adjusted to 0.1-10. The carbide particles as the hard phase are composed of 10-90wt% fine particles having <=1mum size and the balance coarse particles having >=3mum size. When an impact resistant tool such as a metallic header mold is manufactured using the resulting sintered body, the life of the mold is considerably prolonged owing to the superior impact and wear resistances of the sintered body.

Title: Scrambler and data multiplexing method
Inventor: HATAKEYAMA TAKESHI
IPC: H04N19/20
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To allow other recipients than a regular recipient to view data where part of objects is missing by setting a scramble mode to each of multiplexed object data. SOLUTION: Data corresponding to an image object A in a scrambler 11 are not scrambled but data corresponding to only image objects B, C are scrambled and outputted. A descrambler 12 conducts inverse processing of the scrambler 11 and recovers the data. In this case, a scramble signal is analyzed by a CPU 121 and each of object data are fed to cipher decoders 123-125 via a demultiplexer 122. The scramble mode of the object data to be added are analyzed by a CPU 121, which sets the scramble mode to the decoders 123-125 and the data are descrambled by using a scramble key in the separate scramble modes.

Title: Magnetic disk device
Inventor: KATOU MOTOYUKI
IPC: G11B20/10
Filed: 1981-09-30
Abstract: PURPOSE:To protect the information on the defective area of a conductor near the initiation of a track from the destruction due to the inadvertent writing, by counting the servo pulses only for a certain period and synchronously with the index signal. CONSTITUTION:With the transmission of an index signal 2, a flip-flop 3 is set. Then a gate circuit 4 transmits a servo pulse 1 to a counting circuit 5. The circuit 5 starts to count the servo pulses in its reset mode. The resetting of the circuit 5 is identical with the resetting of the signal of an overflow signal line 6. In this respect, a gate circuit 7 prevents the inflow of the signal of a writing signal line 8 to a magnetic head 9 and is set under a writing inhibition state. At the same time, the cicuit 5 continues its counting operation until an overflow arises. The circuit 5 has an overflow when it counts the servo pulses covering from the initiation of a track through the termination of a region  where the information on the defective area of a medium. Thereafter the circuit  5 is set under a writable state.

Title: Pen lifting device in recorder
Inventor: SASAKI NAOTAKA
IPC: G06F3/0488
Filed: 1988-06-27
Abstract: PURPOSE:To enable the soft landing of a pen only by simply controlling the ON/OFF operation of an actuator by a method wherein a cam surface is so shaped as to reduce the travel speed of an actuator when the actuator travels so as to lower one end of a pen carriage to transmit the travel speed to the pen carriage to make the pen land softly on recording paper. CONSTITUTION:When a lever 22 rotates clockwise and a recording pen 7 lowers, a contact position of the lower end surface of the lever 22 and a cam surface 24 is gradually displaced leftward. The lowering speed of the recording pen 7 depends on the lowering speed of a plunger 25 and the change in shape of the cam surface 24. When the cam surface 24 is shaped as a slant surface gradually rising leftward, the rotating amount of the lever 22 is gradually reduced as the plunger 25 lowers. When a direct acting solenoid is used, an attracting force to the plunger 25 increases as the plunger 25 comes closer to the inner center of a solenoid 26 ; the recording pen 7 lowers at a higher speed as it comes closer to recording paper 15. However, the use of the cam surface 24 can reduce the lowering speed.

Filed: 1995-05-31
Abstract: PURPOSE: To realize the total inspection of the absence or presence of un-cut parts of the base plate of an electrical product, in which a metal. plate is insert- molded and which is obtained by cutting a molded article, by a method wherein the vertically moving shaft of a base, to which a plurality of detecting pins are fixed at positions corresponding to the cut parts of the molded article, is raised when uncut parts are present and the raised position of the shaft is detected. CONSTITUTION: When a molded article is moved to an inspection device 11, the vertically moving shaft M of an air cylinder 8 is actuated and lowered, resulting in lowering the inspection device 11 and also detecting pins 19. When the cutting operation of electrode parts is performed correctly with a pressing machine, the detecting pins 19 pass the cut parts, resulting in being judged as a conforming article. However, it even one part is uncut, the lowering of the detecting pin 19 is checked, resulting relatively in bringing the detecting pin 1.9 at raised state. The action results a sliding member 15 also in bringing at raised state and also bringing a detecting plate 22 at raised state. Thus, a gap develops between the detecting plate 22 and a sensor 21 so as to be detected by the sensor 21 and judged as a non-conforming article.
