Filed: 1993-06-21
Abstract: PURPOSE:To detect the change of a recording mode by measuring the operation time of an intermittently operated capstan by a counter and comparing a result with time data determined as a threshold value. CONSTITUTION:The counter 1 receives clock pulse (CP) supplied from a clock pulse (CP) generation circuit 2 through a switch 3, performs counting during the arrival of capstan driving signals SCD and becomes operable with signals delayed in a delay circuit 4. A count value is supplied to a latch circuit 5 and the fall of the signals SCD is latched by the latch pulse LP of a differentiation circuit 6. A comparator circuit 7 compares the latched count value with the threshold of a memory 8 and performs transmission to an AND circuit 9 and one of the thresholds is selected by a mode switching signal MSW. The counter 10 counts control signals CTL out of a magnetic tape during the rotation of the capstan and performs operation only during the arrival of the signals SCD. The output is supplied to the AND circuit 9. When either the output of the counter 10 or the output of the comparator circuit 7 or the both change, the output of the AND circuit 9 also changes from 'H' to 'L'. The change is detected in a control circuit and the mode is surely recognized.

Title: Adjusting method of transmission power in digital mobile telephone system
Inventor: SUTEITSUGU MARUTEIN RAASON
IPC: H04B7/26
Filed: 1991-06-20
Abstract: PURPOSE: To prevent unnecessary interference in nearby channels which use the same frequency for transmission and to make transmission information sufficiently comprehensible by adjusting an output power so that it always keeps an optimum level with respect to a method which controls the transmission power between a mobile station and a base station in a digital mobile telephone system. CONSTITUTION: Measured values of the signal intensity and the signal transmission quality are collected, and their average values are calculated. Assuming that the transmission power at a present point of time (t)0 is kept invariable, these values are used to calculate a predictive value (Z-SS) of the signal intensity and a predictive value (Z-QQ) of the signal transmission quality at a next point of time (t)1 . The transmission power at the next point of time is adjusted based on these predictive values. The transmission power is increased in the case of the predictive transmission quality lower than a desired quality and is reduced in the case of the predictive quality higher than a maximum allowable quality or the predictive signal intensity higher than a maximum allowable value.

Title: Asphalt pavement waste material regenerative dryer
Inventor: FUJIWARA KAZUYA
IPC: E01C19/10
Filed: 1995-06-15
Abstract: PURPOSE: To prevent an asphalt pavement waste material from being deposited and built-up in a cylinder-shaped drum by a non-return blade installed on a supply side of a waste material in the cylinder-shaped drum with a carbon tool steel plate having a specified thickness. CONSTITUTION: A non-return blade 12 is formed with a carbon tool steel plate whose thickness ranges from 1 to 2mm where the non-return blade 12 is installed on the supply side of a waste material in a drum 2. Therefore, the non-return blade 12 is easily vibrated and undulated by a slight impact, which prevents a heated waste material from being deposited on the non-return blade 12. Even when the waste material is deposited and built up to some degree, it is separated so that it may not grow to a lump state. This construction makes it possible to prevent the waste material from being deposited and built up in the drum and remove the waste material even if it is deposited and built up.

Title: Catheter
Inventor: SUZUKI TATSUO
IPC: A61M25/00
Filed: 1991-05-27
Abstract: PURPOSE:To facilitate the smooth insertion into a blood vessel or the like by keeping the thickness of inner and outer tube parts constant at a body section while the thickness of the inner and outer tube parts is kept constant at the tips thereof to mold the body section and the tip part integral without forming any step between the both. CONSTITUTION:Inner tube part 13 at a body section 11 is kept thick constantly while the outer tube part 14 at the body section 11 is kept thin constantly. The inner tube part 13 at the tip part 12 is kept thin constantly while the outer tube part 14 at the tip part 12 is kept thick constantly. In other words, a catheter 10 has roughly a fixed thickness almost over the entire area of the body section 11, namely, relatively less flexibility and has roughly a fixed softness almost over the entire area of the tip part 12, namely, relatively large flexibility. This makes flexibility smooth in change between the body section 11 and the tip part 12 of the catheter 10 thereby enabling smooth insertion into a blood vessel.

Title: Coordinate input device
Inventor: SHINODA NAOTO
IPC: G06F3/0488
Filed: 1985-07-09
Abstract: PURPOSE:To input a coordinate with high accuracy and low cost by providing a coordinate input part to convert the input information into an electrical signal a shift width setting part to fix the shift width by which the coordinate of electrical signal is shifted, and an addition part to add a shift width to the electrical signal. CONSTITUTION:A physical reference point on a board of a coordinate input area 1 is pressed with a pen. The physical position information as the coordinate information of X and Y-coordinates in the coordinate input area 1 is converted into the electrical position information of digital value by a coordinate value detecting part 2 and provided to an adding part 3. Then, in the adding part 3, an offset value which is the prescribed initial value from a shift width setting part 4 is added to the electrical position information. After addition, the electrical position information is indicated on a display 7 via an interface 5 and a host computer 6. If there is a discrepancy of the coordinates between the indicated electrical position information and the physical reference point actually pressed, the combination of plural toggle switches is adjusted in order to remove the error and the final offset value of the shift width is fixed. Therefore the accuracy becomes higher, and the manufacturing cost can be kept low.

Title: No-vibration and no-noise compaction sand pile formation method
Inventor: YAMADA TAKASHI
IPC: E02D3/10
Filed: 1995-05-15
Abstract: PURPOSE: To use a spiral blade attached to the outer peripheral surface of a casing not for assisting intrusion of the casing, but for improving the ground compaction effect. CONSTITUTION: Both penetration and pulling of a casing 3 with a spiral blade 9 are performed, for example, by a rack and pinion casing elevating device 7 in which while the casing 3 is rotated in the opposite direction to the direction of the spiral blade 9, the reaction force from a leader 2 can be obtained. It is preferable that the penetration is assisted by a drilling bit 10 of the tip of the casing 3. Thus, at the time of the penetration, the ground earth is not discharged to the ground, but pressed downward so that the ground compaction effect can be improved.

IPC: F04C2/02
Filed: 1980-10-27
Abstract: PURPOSE: To reduce a vibration and a heat loss by forming a belt-like channel lower than the height of a tooth around the outermost periphery from of a stationary scroll member from the end of scroll to a point on it 180° apart from the end so as to distribute pressure symmetrically in respect to a point.  
     CONSTITUTION: Two scroll member 1, 2 composed of end plates 1a, 2a and laps 1a, 2b formed upright on then, are engaged respectively with each other, with the laps opposed inwards to each other. One scroll member can be turned, apparently making no relative movement to the other. A band-like channel 16' lower than the height of a tooth is formed around an external semicircular part of a stationary scroll member 1 from the end of its scroll. Pressure of gas is thereby distributed simmetrically in respect to a point so that a moment created by deviation pressure distribution applied on the scroll may be reduced.
