Patent JP-H04171355-A (JP)
Title: Controller for automatic transmission
Inventor: ISHIDA HISAO
IPC: F16H59/66
Filed: 1990-10-31
Abstract: PURPOSE:To suppress the rise of the oil temperature and prevent the reduction of the driving power by shift-down-operating the speed change stage determined from a normal speed change map only in the case where the tilt angle is at least a prescribed value with which the oil temperature of a torque converter is raised over an allowable value. CONSTITUTION:A controller 7 reads in the output of a shift position sensor 6, and when the output is in a 'D range', the outputs of a car speed sensor 3, throttle opening degree sensor 4, and a tilt angle sensor 5 are read, and the speed change stage corresponding to the car speed and the throttle opening degree is determined on the basis of a speed change map. When the tilt angle read in from the tilt angle sensor 5 exceeds a prescribed value, shift-down to the determined speed change stage is performed, while if it is judged that the tilt angle does not exceed a prescribed angle, shift-down is not carried out. Accordingly, the slip of a torque converter during ascending a slope is reduced, and the oil temperature rise of the torque converter can be suppressed without reducing the driving power, obviating the need of increasing the cooling specification.

Title: Effect adding device and electronic musical instrument using the same
Inventor: YAMAMOTO TAKAO
IPC: G10H1/08
Filed: 1993-11-02
Abstract: PURPOSE: To add appropriate effects to the musical sounds of plural groups by providing a means which conducts an effect adding by mixing at least two of the outputs of the effect adding means. CONSTITUTION: Output channels chs 1 to 4 of a sound source TG4 are directly inputted to tone color effect adding sections 202 to 205. Thus, the sections 202 to 205 receive different effects. The output of an adder 235 is inputted to a sound field effect adding section 236 and an appropriate sound field effect is added to the output signals of the adder 235 by the instruction from a CPU. Specifically, this effect is a reverberation effect. The scale of the reverberation sound field effect device, which normally requires a large scale, is reduced by providing one effect that is commonly used by plural channels. Furthermore, smaller scale effects such as chorus and distortion are separately provided for plural channels.  Thus, the increase in the entire scale of the effect adding device is suppressed while keeping high degree of freedom in tone color manipulation and the creation of sound field.

Title: Molding method of concrete product and production equipment thereof
Inventor: MURATA HIKARI
IPC: B28B1/08
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent a form from being deformed, the life of the form from being shortened and noise from developing by a method wherein the output of a cylinder for swinging a swinging table is controlled in response to the charge of ready-mixed concrete in the form. SOLUTION: Ready-mixed concrete is charged under the condition that a form 5 is placed on a swinging table (s). In this case, the charge of the ready- mixed concrete in the form 5 is detected with the sensor 3 of the charge of the ready-mixed concrete so as to feed back a detected signal. to a controller CN. Further, the detected signal sent from a swinging strike detector 4 is also fed back to the controller CN. Furthermore, the controller CN controls a pressure controlling valve 6 so as to enhance a feeding pressure in proportion to the charge of the ready-mixed concrete. The controlling form of the valve is to gradually enlarge the output of a cylinder (c) since the start of the charging of the ready-mixed concrete. Accordingly, at the early stage of charging, in which the form 5 is lighter, no stronger pushing-up of the swinging table (s) than necessary is realized.

Title: Foil-wound transformer
Inventor: HIROSE HIDEO
IPC: H01F27/02
Filed: 1988-11-28
Abstract: PURPOSE:To reduce eddy current loss produced and prevent local heating by forming a portion of a tank opposite to a wiring with good conductive metal and forming the other portion of the tank with another metal with a less linear thermal coefficient than said good conductive metal, aid tank containing an insulating medium therein. CONSTITUTION:A tank body 20a opposite to wiring 4, 5 portions housed in a tank is formed with good conductive metal such as aluminum, and a cover 20b portion disposed on opposite ends is constructed with a soft steel material with a less linear thermal expansion coefficient. Hereby, a leakage magnetic flux 12 from the wirings 4, 5 is repelled by the tank body 20 a acting as an electromagnetic shield. Accordingly, magnetic flux entering the tank 20a portion is reduced and hence any loss produced around the tank 20a is also reduced to prevent the tank from being locally overheated. Additionally, at an outer winding 5 portion, a leakage magnetic flux is difficult to be leaked to the outside. Thus, there is reduced a current flowing a direction where radial leakage in the leakage magnetic flux is cancelled out, with a result of the generation of eddy current loss being correspondingly reduced.

Title: Method for detecting refrigerant and refrigeration cycle
Inventor: SATO NARIHIRO
IPC: F25B49/02
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To easily judge presence of a refrigerant in an air conditioner by providing an inside of a refrigerant passage with a detecting agent wherein a color thereof is changed by a refrigerant or air. SOLUTION: A refrigeration cycle is made up of a detecting means 1 for detecting at least either a refrigerant or air, a compressor 2, a condenser 3, an expansion mechanism 4 such as a capillary tube, an evaporator 5, and a piping 6 for connecting these components. As a detecting means 1, there is used a method for detecting propane which is an HC refrigerant wherein a color thereof is changed from orange to brown by a reduction reaction of chromium oxide or a method for detecting moisture in the air wherein a color thereof is changed from blue to pink by a hydration reaction of cobalt complex. Further, the detecting means 1 is made to be able to confirm a change in color from the outside through a pressure resistance quartz glass, and installed near a suction port in the compressor 2.  As a result, since it is possible to easily judge whether or not the refrigerant fills an air conditioner, a refrigerant sealing confirmation work using a gauge and the like becomes unnecessary, while it is possible to reduce an execution time of the air conditioner.
