Title: Magnetic tape cassette
Inventor: OOISHI KENGO
IPC: G11B23/087
Filed: 1982-04-09
Abstract: PURPOSE:To eliminate extreme disorder of pad pressure and to prevent partial abrasion of a magnetic head, by composing a cassette of an upper half part consisting of a couple of upper arms extending to left and right from an upper base part and a lower half part consisting of a couple of lower arms. CONSTITUTION:The upper base part 2 supporting the upper half part of a tape pad 10 have the upper arms 3a and 3b which flex more than the lower arms 6a and 6b to move out into the cassette (to left in a figure) more than the lower base part 5 according to the attitude of a magnetic head 11. Therefore, the pressure that the tape pad 10 presses a magnetic tape 12 against the magnetic head 11, i.e. pad pressure is uniformed by reducing the pad pressure of a part higher than the center by the moving-out operation of the upper base part 2. Consequently, no large pad pressure is applied to the upper part of the magnetic core 11a of the magnetic head 11 which wears relatively easily to prevent the partial abrasion of the magnetic head 11.

Title: Drawing method of blank material for ultrafine metallic pen
Inventor: OOTSUKA KATSUMI
IPC: B43K1/00
Filed: 1982-04-09
Abstract: PURPOSE:To obtain a blank material for a pen point which has a capillary sufficient for supplying and holding of ink and has excellent strength and resistance to abrasion by packing a packing material in the blank material for pen point consisting of an irregularly shaped metallic pipe, drawing the same without mandrel and removing the packing material after cutting. CONSTITUTION:An alloy consisting, for example, of 10% lead and 90% tin is extruded to obtain a blank material 1 for pen point consisting of an irregularly shaped pipe. A packing material, for example, gamma-valeric acid 2 is packed therein at around 160 deg.C and is solidified. A tip 4 is worked to this blank material and the material is drawn through a die 3 for outside reducing, whereby a blank material 5 is produced. Such stage is repeated a number of times to draw the material down to the required pen point diameter. A heat treatment (annealing) stage is usually inserted therein. Since the recrystallization temp. in this embodiment is a room temp. or below, no heat treatment is required. The material 5 is finished by cutting, machining, etc. to a pen point having a drawing end 6 and an ink supply end 7. The pen point is charged into a solvent (water in this case) to elute away the packing material so that the passage for ink is formed over the entire length of the pen point.

Filed: 1978-05-22
Abstract: PURPOSE: To make it possible to perform accurate temperature control even in case of using a thermocouple with small thermoelectromotive force, by using a noise eliminator circuit for the temperature control of a heating body.  
     CONSTITUTION: A voltage developed across thermocouple 21 connected to heating body 12 is impedance-converted by amplifiers 22 and 23 and its differential voltage is detected and amplified by differential amplifier 24 to obtain output waveform (a). This output is inputted to summing amplifier 42 via resistance R4 and also to alternating-current amplifier 41 at the same time. Alternating-current amplifier 41 phase-inverts its alternating-current component only to obtain output waveform (b). Summing amplifier 42 adds the outputs of amplifiers 41 and 24 together to obtain outputwaveform (c) of the direct-current component with alternating current components canceled. Using the thermocouple, therefore, makes it possible to detect accurate thermoelectromotive force with no noise, and consequently accurate temperature control can be performed.

Filed: 1982-04-12
Abstract: PURPOSE:To prevent the deterioration of an inorganic series lining material, by a method wherein exhaust gas containing corrosive gas is replaced with air for exhaust before reaching a dew point of corrosive gas. CONSTITUTION:When an incinerator is brought to a stop, temperature of exhaust gas in a chimney falls. Thereafter, a signal detecting temperature at the inside of the chimney 1 by means of a thermocouple 5 is fed to first and second comparison circuits 91 and 92. If it is found by the first comparison circuit 91 that the detecting signal is below a set value, a signal is fed to a timer 10 from the first comparison circuit 91, and the timer 10 is actuated to drive a blower 6 for specified period of time. This causes air to be blown into the chimney 1 through an air feed pipe 7 from the blower 6, and exhaust gas staying within the chimney 1 is replaced with air before corrosive gas in gas attains a dew point. This causes to automatically prevent deterioration of an inorganic lining material and permits the reduction in a cost required for the lining material.

Title: Drive control device for washing machine
Inventor: FUKUZAWA SOICHI
IPC: D06F41/00
Filed: 1990-03-14
Abstract: PURPOSE:To obtain a time period for satisfactory disentanglement as long as possible during disentangling operation so as to greatly reduce unbalance upon dehydration by discharging water from a washing and dehydrating tank so that the level of water in the tank is steppedly lowered while an agitator is rotated normally and reversely by a rotating angle which is smaller than that during washing or rinsing operation, after the washing or rinsing operation but before dehydrating operation. CONSTITUTION:During water discharging step, an agitator 11 is rotated normally and reversely by a rotating angle with a reversing time period which is shorter than that during washing or rinsing operation. Further, a discharge valve 17 is opened and closed repeatedly by an instruction from a control section 1, and accordingly, the level of water in a washing and dehydrating tank 8 is steppedly lowered during water discharging. During cloth disentangling operation with normal and reverse rotation having a small rotating angle, a time period during which the water level for satisfactory cloth disentanglement is held becomes longer than that in the case of leaving the discharge valve 17 in an open condition, since the water level is steppedly lowered, and thereby the cloth disentanglement can be enhanced further.
