Title: Washing machine
Inventor: KURASEKO TAKAO
IPC: D06F33/02
Filed: 1989-06-08
Abstract: PURPOSE:To stimulate the removal of filth with avoiding damages to cloths and attain a good effect of soak-washing by a method wherein during agitation period, a controller reads out weak rotation cycle or strong agitation cycle from a memory to control the action of a motor, and read out the strong rotation cycle more frequently with the progress of soak-washing. CONSTITUTION:A rotary propeller 8 is reversed for a short time period after a certain rest time period in soak-washing process. The reverse cycle of the rotary propeller 8 includes three patterns: the pattern A generates a reverse current at short intervals, the pattern B a weak current because of a short on-period per unit time, and the pattern C a strong current because of a long one-period per unit time. The soak-washing process is divided into four time periods T1 to T4 for every one hour, and either one of the patterns is read out and performed in each time period after a certain rest time period. In the beginning of soak-washing process, as the effect of detergent is weak, the laundry is agitated by a strong agitation force, and when the detergent works effectively in the later period, a rather strong agitation is applied to stimulate the removal of filth and to disperse filth.

Abstract: PURPOSE:To suppress the inertial slide of an IC and suppress the hindrance for a feeding hook by installing, onto the feeding hook, a pad made of conductive rubber so as to contact with the top surface of the IC when the feeding hook lowers and to depart from the top surface when the feeding hook rises, in a hook-feeding apparatus which pitch-feeds the ICs intermittently. CONSTITUTION:A feeding hook 2 transports ICs 4 intermittently in a prescribed pitch through the vertical movement in reciprocation by the reciprocative movement a' and c' and the reciprocative turn b' and d' of a connecting bar 3. At this time, a pad 6 made of conductive rubber contacts with the top surface of the IC through the lowering movement of the feeding hook 2, and a frictional force is generated between the IC, and a brake power is developed, and the slide due to the inertia of the IC is suppressed, and dusts can be adsorbed by the static electricity generated by the friction. Together with the rise of the feeding hook 2, the pad 6 is separated from the IC 4, and the return operation of the hook 2 is carried out free from hindrance. Therefore, the slide of the IC due to the inertia of the IC is suppressed, and the smooth operation of the feeding hook is permitted.

IPC: H01J29/48
Filed: 1977-12-07
Abstract: PURPOSE: To enable a simple-structure electron gun to form a high-brightness and high-distinction display picture by forming an identical-magnetic-field region between the 2nd and 3rd grids and by providing a resistor layer which forms a pre- focus lens.  
     CONSTITUTION: In the electron gun, an electron flow emitted from cathode 11 is focused by cathode lens formed of cathode 11, and the 1at and 2nd grids 12 and 13. In the region between the 2nd and 3rd grids 13 and 14, the action of the prefocus lens can be obtained by grids 13 and 14 and resistor layer 15, and this lens action increases the focusing action of an electron flow by elongating length (l) of resistor layer 15 to a certain length. As a result, the electron flow can be throttled tight and its divergence angle (α) can also be made small easily. Characteristics of the electron gun of this constitution are shown by curve 50 (the solid line express conventional ones), and beam current ID can be controlled greatly with beam diameter DT held nearly constant.

Title: Semiconductor integrated circuit device
Inventor: UDAGAWA SATORU
IPC: G11C11/407
Filed: 1986-06-25
Abstract: PURPOSE:To obtain a semiconductor integrated circuit device such as a semiconductor storage device with high circuit integration and low power consumption and further stabilized operation by making an output voltage of a 2nd voltage generating circuit at the time of supplying leak current nearly coincident with an output voltage of a 1st voltage generating circuit. CONSTITUTION:The absolute value of an output voltage of a voltage generating circuit VG2 having comparatively small current supply capability is smaller rapidly because a substrate back bias current Ibbs is larger, while the absolute value of an output voltage of a voltage generating circuit VG1 having comparatively large current supply capability is not so much changed even if the substrate back bias current Ibbs is large. The maximum output voltage of the circuit VG2 is -(Vcc-Vth) and an output voltage of the circuit VG2 in giving a leak current of a certain degree for the countermeasure of power voltage bump is selected to be nearly -(Vcc-2Vth) at the standby state of a dynamic RAM. Thus, even if the dynamic RAM is selected and the operation of the voltage generating circuit VG1 is started, (the substrate back bias voltage -a potential at a -Vbb output terminal) does not show a large fluctuation.
