Title: Supply of water for forming ice and snow exhibiting body
Inventor: TAKAZAWA TAKASHI
IPC: F25C1/02
Filed: 1988-07-21
Abstract: PURPOSE:To form a low-temperature artificial scene exhibited in a room more efficiently by ice figures or the like by a method wherein low-temperature water in a water tank is sprayed into a low-temperature space, in which ice and snow displaying bodies are formed, while water on a floor surface is returned into the water tank through a heater. CONSTITUTION:Low-temperature water 21 in a water tank 20 is sprayed into a low-temperature space 1, in which ice and snow displaying bodies 2 are formed, while water 21 on the floor surface F of the low-temperature space 1 is returned into the water tank 20 through a heater 28. One part of the water 21, sprayed in the low-temperature space 1, is frozen and forms ice and snow displaying bodies 2. The other part of the sprayed water 21 drops on the floor surface F of the low-temperature space 1 and is cooled by cold air in the low- temperature space 1 whereby cold water 21 is returned into the water tank 20 thereby keeping the temperature of the water in the water tank 20 at a low value and increasing the efficiency of forming of the ice and snow displaying bodies 2. On the other hand, a heater 28 is provided in order to prevent the freezing of the water 21, dropped on the floor surface F of the low-temperature space 1 on the way of returning process.

Filed: 1989-07-14
Abstract: PURPOSE:To obtain a magnetic head, which keeps stable contact with a disk, rich in durability by fitting an edge on an opposite side to a side, where a reader is provided, to a head supporting device so that the head can get the strongest contact with the magnetic disk and contact pressure can be lowered toward the reader side. CONSTITUTION:A magnetic head 3 is fitted to a supporting device 2 so that the lengthwise direction of the head can be correspondent to a traveling direc tion a1 or a2 of a magnetic disk 1, the edge in a breadthwise direction on the opposite side to the side equipped with a reader 32 can get the strongest contact with the disk and the contact pressure can be lowered toward the side equipped with the element 32. Accordingly, the contact area of the head to the disk 1 is decreased and the head can naturally and stably follow up the high-speed traveling of the disk. Thus, the head can also follow up the undulation of the disk as well. Since the contact area is reduced, the quantity of the both mag netic disk and head to be worn is decreased and the durability is improved.

Title: Film automatic rewinding device
Inventor: KIMURA HIROYUKI
IPC: G03B17/42
Filed: 1981-11-13
Abstract: PURPOSE:To rewind a film automatically when winding is terminated, by using outputs of a photocoupler, which detects the transportation state of the film, and a roller, which detects whether the film is present or not, to start and stop the rewinding. CONSTITUTION:A photocoupler 35 which detects perforations 41 to detect the transportation state of a film is provided in the transportation path of a film 34, and a detecting roller 18 which detects whether the film is present or not is provided on a spool 17. When the film approaches the terminal during winding, the turn-on/off constant signal of the photocoupler 35 is not steady. This is detected to reverse a motor M1, and a gear 8 is allowed to engage with a gear 27 to start the rewinding. When the film 34 runs out, it is detected by the detecting roller 18 to turn off a switch SW1, and the power supply to the motor M1 is stopped to stop the rewinding. Therefore, the film is rewound automatically when the winding is terminated, and thus, handling is very convenient.

Title: Schmitt circuit
Inventor: NAGAO HISAO
IPC: H03K3/2897
Filed: 1984-08-29
Abstract: PURPOSE:To set a hysteresis irrespectively of the scale of the electric current of a Scmitt circuit in the current mirror circuit cross-linking type Schmitt circuit, by setting the emitter area ratio of two transistors forming a current mirror circuit to one other than '1'. CONSTITUTION:Emitter area A, B, C, and D of transistor Q1, Q2, Q3, and Q4 are set to satisfy A=D, B=C, B/A=C/D=a>1. Inversion of the initial state I1>I2 of electric current under this condition takes place when I1=I0/(1+a) and the inverted state is again returned to the initial state when I1'=aI0/(1+a). That is to say, a hysteresis exists in this case and, since the hysteresis is I1'/I1=a and determined in accordance with the emitter area ratio only, the hysteresis does not depend upon the total current. Therefore, the hysteresis can be set irrespectively of the scale of the electric current of the circuit.
