IPC: F28F19/02
Filed: 1981-03-20
Abstract: PURPOSE:To make it possible to collect heat not only at a temperature around the acid dew point but also up to an ordinary temperature level by a method wherein bare pipes whose inner and outer surfaces are covered with enamel layers are used as anti-corrosive heat transfer pipes. CONSTITUTION:Each of the bare pipes 2 is made to have suspension holes 2 at portions near both ends thereof, respectively, and the inner and outer surfaces of the pipe are enamelled simultaneously by suspending the pipe with a hook 3 in such a manner that the hook 3 is first inserted into one of the suspension holes 2 to thereby suspend the pipe during the enamelling process for the lower half of the pipe and then inserted into the other suspension hole after the pipe is turned upside down to thereby suspend the pipe during the enamelling process for the upper half of the pipe. Further, two of the above pipes 2 are inserted into the openings of a U-shaped pipe 7 and the gaps between the pipes 2 and the U-shaped pipe 7 are filled with a bonding agent or a sealing material 8 to connect the pipes tightly with each other so that the leaking of a liquid flowing through the pipes is prevented. The heat transfer pipes thus finished have excellent anticorrosive properties and are able to collect heat not only at a temperature around the acid due point but also up to an oridinary temperature level.

Title: Motor assisted bicycle
Inventor: MATSUMOTO TOSHIHIRO
IPC: B60K1/04
Filed: 1995-02-28
Abstract: PURPOSE: To accurately control the auxiliary driving force in a motor assisted bicycle by connecting a flywheel diode in parallel to a series circuit of a DC motor and a motor current sensor to correctly detect the motor torque based on the armature current of the DC motor. CONSTITUTION: In a motor assisted bicycle which is driven by the main driving force by the input and the auxiliary driving force by a motor, the battery current to be fed to a motor 101 from a battery 102 through a switching element 103 is turned on/off at the prescribed frequency by a switching element 104. The current flowing a motor 101 also flows during the off-period of the switching element 104 through the flywheel operation of the diode 104, and a motor current sensor 105 detects the net motor current. Because the motor torque is essentially proportional to the motor current, the motor current sensor 105 can correctly detect the motor torque, i.e., the auxiliary driving force compared with the case to detect the battery current.

Title: Pachinko game machine
Inventor: OMOTEGAWA HACHIROU
IPC: A63F7/02
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To turn the frequency of the continuous opening of a ball receiving member at the time of a special winning state to a fixed number and to vary the possibility of the generation of the special winning state. SOLUTION: Based on the entrance of a game ball to passing gates 14a and 14b, the fluctuation display of a pattern display part 15a is started. When a special pattern '7' is displayed when a pattern is stopped, the opening/closing piece 15a of an opening/closing type start port 15 is opened. When the game ball enters the opening/closing type start port, the ball receiving member 23a of a variable winning device 20 is opened/closed for two times. At the time, when the game ball enters the variable winning device and also enters a continuous winning port, the pattern display part 21 stops fluctuation. When the stopped pattern displays the pattern 'F', a specified state is attained.  When the specified state is attained, the frequencies of the opening of the opening/closing piece of the opening/closing type start port thereafter is increased to three times until the frequencies of the special state becomes '0'. Thus, the game ball easily enters the opening/closing type start port and the possibility of ball entrance to the continuous winning port, that is the generation of large winning, is improved as well.
