Title: Manufacture of odd-shaped ice
Inventor: TAGUCHI TETSUYA
IPC: F25C1/20
Filed: 1987-10-27
Abstract: PURPOSE: To facilitate making of transparent odd-shaped ice with simple work by simply taking out ice inside an ice making retainer to obtain flexibly shaped ice according to the shape of the ice making retainer. CONSTITUTION: Ice making raw water in an ice making retainer 1 is significantly affected by the agitation of the ice making raw water 14 existing outside it through a water passing hole 5 and an ice freezing layer growing on the wall of each ice making retainer 1 also always undergoes freezing from renewed ice making water to be further turned transparent. In this manner, the ice frozen in the ice making retainer provides transparent ice totally. The frozen layer grown on the wall of an ice making can entirely wrap the ice making retainer 1 and the ice making work is stopped when all of the ice making raw water is frozen sufficiently in the ice making retainers 1. Then, a drop tube 11 is pulled up to withdraw the ice making can 10 from a cooling brine tank 16 and the ice grown inside is taken out of the ice making can 10.  After the ice is melted, the ice making retainers 1 are taken out individually and an upper mold 3 is taken off a lower mold 2 to obtain a grown spherical ice therein.

Title: Input circuit for semiconductor integrated circuit
Inventor: SUMI KATSUAKI
IPC: H03M1/36
Filed: 1985-11-29
Abstract: PURPOSE:To decrease the number of emitter followers serving as buffer amplifiers by using an emitter follower transistor where the analog input signal is inputted to the base and the output signals are outputted to plural comparators. CONSTITUTION:A differentials amplifier for comparison consisting of transistors TRQ3 and Q4 compares the analog signal inputted to an input terminal 2 with the voltage obtained by processing the reference voltage inputted to an input terminal 3 for reference voltage by an emitter follower consisting of a TRQ2 and a constant current source I2. When a clock input terminal 5 has a level higher than a clock input terminal 6, a TRQ5 is turned on and a constant current source I3 flows through the TRQ5. Then said differential amplifier becomes active. The difference of the base voltage between the TRQ3 and Q4 is amplified. Thus an output corresponding to the levels of the analog input signal and the reference voltage is obtained at each collector. The collector voltage of the TRQ4 is extracted through an output terminal 7 in the form of an output via an emitter follower consisting of a TRQ9 and a constant current source I4.
