Abstract: PROBLEM TO BE SOLVED: To prevent floating of a foundation due to freezing by supplying warm air from the inside of a building to a hollow space made in a concrete foundation block thereby preventing freezing in the ground around the foundation blocks in severely cold winter season. SOLUTION: A concrete foundation block 1 for a building comprises a building frame 2 for supporting the structural member M of the building and a footing portion 3 having a hollow space 4 throughout the whole length inside, and its plan view can be a straight shape, L-shape, T-shape, cross shape or the like. Foundation R comprising rubble stone K and mat foundation is formed on the ground, on which various kinds of concrete blocks 1 can be installed by adequately combining them together for building a continuous footing. In part of concrete block 1, an expanded portion reaching the top surface of the structural portion 2 is provide and a vertical hole communicating to the hollow portion 4 is formed and used as an air intake and exhaust passage for supplying indoor warm air to the hollow space 4.  By doing this, in a region where the freezing depth of ground is large in a severely cold winter season, freezing of ground around the foundation block 1 can be prevented and the floating of the foundation due to freezing can be also prevented.

Title: Electronic apparatus
Inventor: MURATA HIROSHI
IPC: G06F3/14
Filed: 1978-02-15
Abstract: PURPOSE: To divide and display information into several pieces, and then to indicate split display when there are more display contents than display digits, by comparing the both.  
     CONSTITUTION: For example, memory register R is stored with 13-digit information, and display unit DP has 8-digit display body DPD. Decision circuit J compares data stored in register R with the number of digits of display unit DP. Now, when register R is stored with data of more than eight digits and FF gives output antenna Q "1", the contents of signal line L1 are displayed by display body DPD by way of gate circuit TG1, display control circuit DCC and signal line L3, and the antenna-Q output of the FF is transferred via gate G2, so that right-arrow display unit RAD will come on. With key switch KS depressed next, the Q output changes into "1"  through the inversion of the FF, the contents of signal line L2 are displayed, and  left-arrow display unit LAD comes on by the output of gate G1. When the effective  numeral of register R is within eight digits, the output of decision circuit J is "0" and  neither arrow display unit RAD nor LAD comes on.

Title: Seek control circuit for optical disk device
Inventor: KOMINE SHIGERU
IPC: G11B7/085
Filed: 1989-01-26
Abstract: PURPOSE:To attain stable pull-in of tracking by estimating an eccentric rotating speed from a rotary angle at the end of seek and applying speed correction for disk eccentricity with respect to the absolute speed detected by a speed detector or a position detector. CONSTITUTION:When an optical disk 1 is driven with eccentricity at an angular velocity omega, an eccentric rotating speed caused when a track of the optical disk 1 crosses a stationary light spot P in a moving direction r' of an actuator 3 depends on the rotary angle. Moreover, the eccentric rotating speed is negative when the track crosses inward and positive when the track crosses outward. Then the eccentric speed in response to the rotary angle is stored prior to the operation, and the actuator 3 is moved to cancel the eccentric rotating speed in the operation for the seek operation. Then the eccentric rotating speed is estimated from the rotary angle at the end of seek and the eccentric rotating speed is corrected with respect to the absolute speed detected by a speed detector or a position detector. Thus, the tracking pull-in operation is made stable to reduce the seek time.

IPC: H03K5/08
Filed: 1982-02-05
Abstract: PURPOSE:To eliminate noise completely with very simple circuit constitution, by forming the circuit with a rectifier circuit, an FF inputting the rectified output and the 2nd FF inputting the output of the FF. CONSTITUTION:An AC sinusoidal wave (e) is produced in an output of a transformer T, this is rectified with diodes d1-d4 and inputted to a set input S1 of an FF circuit FF1 and a reset input R1, respectively. Thus, a pulse is generated in outputs Q1, Q'1 of the FF1. A pulse is generated at outputs Q2, Q'2 of an FF circuit FF2 with the pulses and the AC sinusoidal wave is converted into a rectangular wave. In this case, since the FF1 is not responsive to noise overlapped on the sinusoidal wave, the noise is completely eliminated at the FF1. Further, when a noise decreasing the sinusoidal waveform is mixed and the result is lower than the threshold level, the FF1 is responsive and a pulse is generated at the outputs Q1, Q'1. But no effect is given to the output of the FF2 even if these pulses are applied.
