Title: Production of confectionery
Inventor: OZAKI TAMIO
IPC: A21B5/00
Filed: 1986-05-23
Abstract: PURPOSE:To produce a confectionery without breaking a granular shape, by heating a confectionery material, applying compression thereto while heating after the lapse of a given time, then releasing the compression, further continuing the heating while keeping the distance between the top and bottom forces and removing steam in at least the compression stage. CONSTITUTION:A confectionery material 6, e.g. polished glutinous rice etc., is put in a middle force 1 and top and bottom forces 2 and 3. Heating is carried out from the start to end of production. A given time from the start of production is a process for steaming and kneading the glutinous rice. After passing through the process, the top force 2 is lowered to compress the material 6, produce and form a rice cake. The pressure applied to the top force 2 is then reduced to zero and only the weight of the top force 2 is applied to the glutinous rice to carry out adjusting of the shape, drying and roasting. Steam generated from the confectionery material 6 throughout the heating and compressing is released from a clearance 4 to the outside. As a result, the granular shape is held and firmly bonded to form the glutinous rice into a given shape.

Abstract: PURPOSE:To accurately position an FP type IC in X, Y and Z directions before being mounted on a printed board by providing a reformer area for correcting deformation of an IC lead in the Z direction between an area of a tray unit of an FP type IC loader and an area of a positioning unit for placing by correct positioning. CONSTITUTION:An FP type IC (W) picked up from a tray unit 2 by a transfer unit 3 is placed in a forming lower die 12 of a lead reference unit 10 by placing a lead part thereof on the forming lower die 12. Then, once a clamp drive part 14 is actuated, a forming upper die 13 is lowered to make contact with the forming lower die 12 with given pressure and hence clamp the IC lead. Hereby, the IC lead is corrected if it is deformed in the Z direction, permitting all leads to be aligned to a same level shape. Thereafter, the clamping is released to raise the forming upper die 13. Further, the IC is picked up by a robot arm and fed to a positioning unit 5 for its positioning in X and Y directions including other necessary processes. Thus, mounting accuracy of an IC can be improved and prevent any problem such as bad soldering from being produced.

Abstract: PURPOSE:To secure a sufficient ventilating air flow quantity so as to improve the cooling efficiency by operating a shutter, damper plate, and air direction controlling plate in an interlocking way. CONSTITUTION:When a cooling/heating switching room is used as a cooling room, the first and second vent ports 30 and 31 are opened by operating a shutter 33 from an operating section.

When the room is used as a heating room, a heater 29 is energized and, at the same time, the ports 30 and 31 are closed by means of the shutter 33. Then the damper plate 34 opens the vent port to the fan 28 chamber and the plate 36 retreats from the dividing position. Therefore, a sufficient ventilating air flow quantity can be secured to a cooler 26 and the cooling efficiency can be improved. In addition, heavy frosting on part the cooler 26 can be prevented.

CONSTITUTION:The feedback section of the operational amplifier 6 consists of the resistor R11 and the diode D11, the controlling current Ii is impressed to an antiphase input, and its output voltage is impressed respectively to control terminals 4, 5 via the RF choke circuit (acting like a voltage follower function) comprising an operational amplifier 7, capacitors C21, C22 and resistors R21-R23. Through the constitution above, the attenuation AT to the RF signal is expressed as ATT=20log10[(2R0/R11)xe<x>+1], where x=(q/KT)R11Ii and R0 is the characteristic impedance of the RF circuit. When the (x) is sufficiently large in the equation above, the ATT is expressed as ATT 20log10(2R0/ R11)x+alphax, (where alpha is a constant), and even when the control Ii is changed, the change in the 1st term is less in the equation above and the ATT is changed nearly in proportion to the current Ii. Further, the effect of the temperature change is similar to the impressed current change in proportion to the absolute temperature.
