Title: Semiconductor device
Inventor: AKAOGI TAKAO
IPC: H03K19/00
Filed: 1992-09-17
Abstract: PURPOSE:To reduce current consumption and to stably decrease and supply a power supply voltage from outside by using a transistor as a voltage decreasing means and driving the transistor by applying a reference voltage on a prescribed level to the gate of the transistor. CONSTITUTION:As a voltage decreasing means for decreasing a power supply voltage Vcc to a prescribed internal voltage Vci, a transistor Q connected between the line of the power supply voltage Vcc and the generation node N of the internal voltage Vci is used.

Title: Semiconductor memory circuit
Inventor: NAGAI KENJI
IPC: H01L27/095
Filed: 1991-09-02
Abstract: PURPOSE:To obtain a semiconductor memory circuit whose number of elements is reduced which is operated at a high speed by using two tristate gates which are respectively controlled by a clock signal and an inversion clock signal. CONSTITUTION:When a non-inversion clock signal CK is 'L', a tristate gate TG2 is opened, and a TG1 drives an output load, and switches an output, that is, information. When the signal CK is 'H', and an inversion clock signal CKB is 'L', the output of the TG2 holds the output potential of the TG1 before the switching of the signal CK, and the output of the TG1 is turned to 'H', and the TG1 is opened. Therefore, the output potential of the output QB of a data latch circuit is not related with the input, and this circuit is operated as the data latch circuit. Therefore, a delay time from the switching of the signal CK until the output of the data is decided by the element TG1, and used as a required time for a signal transmission for one stage of the gate. Thus, the number of invertors can be reduced by one while the high speed operability of the data latch circuit can be maintained. And also, it is enough for the gate TG2 to hold the output potential, so that this circuit can be made compact even when the size of an output impedance is large, and a low power consumption can be attained.

Title: Seal structure of bearing portion
Inventor: AZUMA YOSHIO
IPC: F16J15/18
Filed: 1994-09-16
Abstract: PURPOSE: To prevent each seal groove inside from becoming a recessed/ projecting shape due to wear and heat deformation by providing a recessed portion at each seal groove of a drive shaft, providing at the same time at the side portion of each seal ring a projecting portion that is put into the recessed portion. CONSTITUTION: In a case in which a drive shaft 1 and a housing 2 are rotated relatively at a low speed, a seal ring 5 in a seal groove 1b follows the housing 2 and is rotated due to radial difference between its inner and outer peripheries. However, when the relative rotary speed of the drive shaft 1 and the housing 2 becomes high, the pressure chamber inside becomes high pressure due to heat expansion, so the seal ring 5 is energized to the lower pressure side in the seal groove 1b, and a projecting portion 5a is put into the recessed portion 1c of the seal groove 1b. Then, the seal ring 5 follows the drive shaft 1 and is rotated, and slides only between the inner periphery surfaces of a bearing 2a.  Each bearing 2a of the housing 2 uses a metal such as steel, so even if frictional heat is generated due to slide with the seal ring 5, there occurs no fear of the bearing 2a inner periphery surface causing heat deformation.
