Title: New coupler for photography
Inventor: KANEKO YUTAKA
IPC: G03C7/38
Filed: 1990-10-19
Abstract: PURPOSE:To enable cyan colouring matter image not generating any hue change against heat, humidity and light to be formed by a method wherein a specified pyrazolotriazine derivative is used. CONSTITUTION:A coupler for photograph expressed by a formula I is used. In the formula I, R1, R2 and Y denote hydrogen atom or its substituent, X denotes groups reacted with hydrogen atom or oxidization substance of color development main constituent and removed from it, Z1 and Z2 denote O, S or N-R3, and R3 denotes hydrogen atom or its substituents. Z1 and Z2 may be the same to each other or different from each other. Substituents expressed with R1 to R3 may have anti-diffusion groups such as long-chained hydrocarbon group or polymer residual group or substituents such as electron withdrawing groups. As the substituents expressed by Y, there are groups which can be removed under an alkaline condition or substituents coupled off under a reaction with oxidization substance of the development main constituent. With such an arrangement, it is possible to form a cyan colouring matter image not generating any change in hue against heat, humidity and light.

Title: Drive circuit of semiconductor switching element
Inventor: USHIKI SHUICHI
IPC: H03K17/732
Filed: 1985-12-12
Abstract: PURPOSE:To obtain the drive characteristic with high efficiency and high speed by supplying the energy required for turning-off of a semiconductor switching element from a main current path of the semiconductor switching element so as to eliminate the need for a large reverse bias current source. CONSTITUTION:When a drive transformer 15 is saturated after the semiconductor switching element 1 reaches the ON-state completely, a winding N2 is short- circuited and a forward gate current is not supplied. In this case, the short- circuit between the gate and cathode of the element 1 is prevented by the forward voltage drop of diodes 29, 30. When the switch element 3 is closed and the switch element 2 is opened, a voltage taking a mark . as the negative pole is generated in the winding N3, the voltage biases the forward voltage of the diodes 29, 30 to constitute the reverse gate current path, through which the reverse gate current is supplied. In this case, since all the currents supplied from the winding N2 are fed to the gate of the element 1, the efficiency is high.

Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce a necessary current and to improve measures for heat by reducing a current flowing into a starting circuit to about zero when a band gap circuit reaches a prescribed value. SOLUTION: A current whose peak value is about <=7 μA is supplied to the starting circuit 100 for 1-3 μsec at first and voltage is applied to the band gap circuit 102 supplied to the circuit 100. When target band gap reference voltage is 1.25 V e.g. whether at least a part of the circuit 102 reaches a prescribed voltage value 800-900 mV or not is judged, and when the circuit 102 does not reach the prescribed voltage value yet, the current in the circuit 100 is continuously increased. When the circuit 102 reaches the prescribed voltage value, the current in the circuit 100 is controlled so as to be approached to zero. Thus the efficiency, reliability and heat measures of the starting circuit 100 can be improved by driving the circuit 100 with a low current.

Title: Absorption type air conditioning apparatus
Inventor: IKEDA KATSUTO
IPC: F16K31/24
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To improve durability by restricting the concentration of cooling water cooled by an evaporation type cooling column while abolishing an electromagnetic drain valve. SOLUTION: A drain port 65a is provided on the bottom of a cooling water tank 65. There are arranged in the cooling water tank 65 a float 68, an opening/ closing valve 69 to open or close the drain port 65a and a spring means 70 to link them. Evaporation with a cooling column 61 proceeds and when the water level in the cooling water tank 65 falls down to a low level lower than a valve closing level immediately before the pulling of the spring means 70 starts, cooling water is supplied into the cooling water tank 65 until reaching the valve opening water level to dilute the cooling water. When the water level reaches the valve opening level, the opening-closing valve 69 opens the drain port 65a by a floating force of the float 68 and a return force of the spring means 70 to drain the cooling water.  When the water level falls down to the valve closing level, the opening/closing valve 69 closes the drain port 65a and a blowdown operation ends. Thus, a dilution of the cooling water is accomplished without using any drain valve.
