Title: Shelf method for ink jet recording head
Inventor: MAEOKA KUNIHIKO
IPC: B41J2/175
Filed: 1993-07-19
Abstract: PURPOSE:To effectively prevent ink from being dried and require no adhesive tape to be stuck to a nozzle port and no expensive package for protecting ink from drying by packing a shelf material, which is a solid at normal temperatures and is soluble-in ink, in a nozzle. CONSTITUTION:An ink jet recording head has an element wherein a silicone base plate 3 including a heater, having multilayer films formed thereon, is integrated with a top plate 4 forming therein a common liquid chamber 7 with the aid of a resin layer, and this element and a printed circuit board 8 are mounted on a base plate. The element is liquidly coupled to an ink tank by a supply member 10, and ink supplied into the supply member 10 fills up the common liquid chamber 7 and a nozzle 6 and is discharged from a discharge port 5 by power supply to a heater provided on the wall face of the nozzle 6. In the case where the recording head is delivered, a shelf material, which is a solid at normal temperatures and is soluble in ink, is packed in the nozzle 6, whereby ink is prevented from being dried.

Title: Magnetic head
Inventor: GOTO TADAHIKO
IPC: G11B5/23
Filed: 1987-07-18
Abstract: PURPOSE:To improve the S/N to an off-track by forming a wide gap part of a part corresponding to the wide gap on both ends of a head gap. CONSTITUTION:The wide gap parts 2, 2 are formed on both ends of the head gap part 1. Although the gap of the part by a distance of 2(DELTAx) from the end of the head at the inner side is bridged over an old data (noise) in this way, the head with a wider gap by the length equal to that of the part is used to decrease the level of a detected noise signal, thereby preventing much reduction in the S/N. The gap of the wide gap parts 2, 2 is to be selected to a gap being 2-10 times the width of the conventional gap. Since the S/N to the off-track is improved, no positioning mechanism with high accuracy is not needed and high track density is attained, thereby making a large capacity for the magnetic recording and reproducing device.

IPC: F16K37/00
Filed: 1981-11-09
Abstract: A safety valve, coupled to a pressure chamber, includes a closure element which is translatable substantially along a reference axis. The device includes a spindle nut (60) and an associated extension member adapted for coupling to the spindle (14) of the valve. The extension member includes an annular permanent magnet (76) positioned thereon having its principal axis co-linear with the first reference axis (70). This magnet assembly provides a substantially uniform magnetic field at its periphery which is substantially symmetrical about the reference axis. The device further includes a cylindrical housing member (40) which includes a generally cylindrical inner surface which extends about and is uniformly displaced from the magnet assembly (76) for substantially all positions of the magnet assembly as the spindle moves along the reference axis. The cylindrical housing assembly includes one or more reed switches (50, 52) in close proximity to the inner cylindrical surface aligned with their principal axis parallel to the reference axis. The spacing between the magnet assembly and the reed switches is selected so that as the magnet assembly passes one of the reed switches, that reed switch changes from open to closed, and then back to open again.

Title: Timer circuit
Inventor: KUSAKABE MIZUO
IPC: H03K21/40
Filed: 1992-06-15
Abstract: PURPOSE:To accurately count the event inputs in order to prevent the conflict between the strobe and event inputs by outputting the strobe input to a control circuit synchronously with a clock pulse having the different phase from the clock pulse used for the event input. CONSTITUTION:The clock input which is applied to an external event input terminal 1 as an event input is turned into a signal that is synchronous with a clock pulse by a synchronizing circuit 6. This signal increases the count value of a counter circuit 2 in response to the start of the clock input. Meanwhile the strobe input applied to an external strobe input terminal 3 is turned into a signal that has the different phase from the clock pulse of the circuit 6 by a synchronizing circuit 7. Receiving the strobe input, a control circuit 4 stores the count value of the circuit 2 in a capture register 5 in response to the start of the strobe input. Then the circuit 4 resets the count value of the circuit 2. Therefore the event input never conflicts with the strobe input.
