Title: Melting and excavating device of ice surface of frozen road surface by thermal conduction
Inventor: MURAKAMI KATSUSHI
IPC: E01C11/24
Filed: 1994-05-20
Abstract: PURPOSE:To increase the frictional coefficient of a road surface and prevent slipping, by providing a pillar-shaped shaft melting and excavating an ice surface, in which the front end heated in a substance having a large electric resistance is spherical. CONSTITUTION:A pillar-shaped shaft 27 and a spherical front end 1 are heated by a substance 4 having a large electric resistance like nichrome wire in which electric current is conducted from an electrode 2 through current plates 3 as an electric source. A melting and excavating device of ice surface for a frozed road surface is transferred by one round along an anti-clockwise ellipse course. When the device approaches the road surface 21, the shaft 27 released at the guide plate tail 15 comes near to ice 20 on the road surface and melts the ice and makes a hole. Then the cooled shaft 27 is heated while closely positioning the electric current plate 3 and the electrode 2 and transferring one round, at the front end 16 of the guide plate. In this way, ice is melted and a number of holes are opened and hence, the surface of ice 20 becomes uneven and the frictional coefficient of the road surface 21 is increased and slipping is prevented.

Title: Memory control system
Inventor: ISHIDA WATARU
IPC: G06F12/08
Filed: 1985-06-28
Abstract: PURPOSE:To produce freely a user program by dividing a logic space into an area where the mapping is carried out and another area where no mapping is carried out and therefore attaining the accesses to the same memory from both areas. CONSTITUTION:When a logic space is sexadecimal and has 10000000 bytes, the accesses are given to a memory in a physical space via a memory control unit MMU through addresses 0-7FFFFFF within a logic space together with addresses 8000000-FFFFFFFF where the accesses are carried out with no intervention of the unit MMU. Here if an access is given to an address 1000 in the logic space, an access is also given to a physical space according to a conversion rule. While an access is given to the address A001000-8000000=2001000 in the physical space. Therefore a user can produce freely programs at and after the address 0 in the logic space.

Filed: 1982-08-17
Abstract: PURPOSE:To prevent the mutual interference of the operation of adjacent FETs by surrounding one of Schottky junction gate type FETs formed by insularly isolating mutually on a semi-insulating substrate with an electrode of the prescribed voltage. CONSTITUTION:A GaAs active region 31 is insularly formed on a semi-insulating substrate 32, and an MES FET is formed with ohmic electrodes, 33, 34 and a Schottky electrode 35. A guard electrode 36 is formed of the same metal as the electrodes 33, 34 or 35 around the FET on the substrate 32. An insulating film is covered, the electrodes are respectively connected through connecting parts 37, 310 to wirings 311-313, and the wirings 312 and the electrode 36 are grounded. According to this configuration, lines of electric force which are directed toward the FET in the guard electrode of the lines of electric force produced out of the guard electrode are all terminated at the electrode 36, and the operation of the FET of the inside is not affected by the variation in the voltage out of the guard electrode at all. In other words, even when a leakage resistance is presented in the substrate 32, the FET may be electrically isolated.

Title: Optical reception equipment
Inventor: AIISO ATSUSHI
IPC: H04B17/00
Filed: 1986-06-18
Abstract: PURPOSE:To prevent malfunction of the titled equipment due to white level noise component at no signal by extracting a white level noise component and a reception signal component, supplying them to a comparator to apply comparison and stopping a digital signal output when no reception signal compo nent output exists. CONSTITUTION:A noise voltage excluding a signal component is obtained by a white noise detection means 8 and the entire voltage of the noise and signal is obtained from a signal + white level noise detection means 9. If the signal component voltage is lost from the entire voltage, its level is fluctuated remarkably, and since no change exists in the detected voltage of the means 8, the comaprator 10 detects non-signal easily. Moreover, even if a variation exists in the gain of a photoelectric transducer 1 and a broad band amplifier 2, since the comparator 10 acts like both the inputs similarly, the output of the comaprator 10 is immune to the variation of the characteristic. Thus troublesome threshold adjustment which had been required in a conventional equipment is not required.
