Title: Information selector
Inventor: NORIFUSA MASAYA
IPC: H03M11/04
Filed: 1989-08-23
Abstract: PURPOSE:To decrease the instruction frequency and to detect and select a subject in a short time by rearranging a symbol string and using sequential instructions when subjects are numerous to select and decide a subject. CONSTITUTION:A rearrangement means 2 rearranges the symbolized information according to a rule, and a display deciding means 5 decides a subject after displaying it by means of the rearranged symbol string. At the same time, the subject can also be pointed by a direct pointing means 6. However it is hard to detect the relevant subject and a long time is needed to decide the subject if the number of subjects is large. In such a case, a sequential instructing means 7 is used to successively select the subjects via a part of the symbol string, for example, then instructs these subjects in sequence. Then the means 6 decides a specific subject. Thus it is possible to decrease the operations which frequently move the part to be displayed back and forth for selection/decision of a subject out of a subject list, and to reduce the re-displaying frequency caused by said moving operations. As a result, a desired subject is detected in a short time and in a small number of operations.

Title: Fluorescent lamp
Inventor: YANAGI TADASHI
IPC: H01J61/067
Filed: 1983-11-16
Abstract: PURPOSE:To prevent the generation of irregular flickering by suppressing the toxication of the electrode by specifying the distance between the free end of lead-in wires and the location where the leg of a filament coil is fixed. CONSTITUTION:Each lead-in wire 4 has a section 9 with a large diameter, which is located apart from the end 5 of the lead-in wire 4 by a distance (h) of at least 5mm.. The legs 10 of a filament coil 6 are fused to the sections 9 by spot welding. Because of the above constitution, during the anodic cycle of the electrode, electrons do not flow into the filament coil 6 and most of them flow into areas of the lead-in wires 4 located between the center of the axis of the legs 10 and the end 5 of the lead-in wires 4. Accordingly it is possible to protect the filament coil 6 from electronic impact. Furthermore, it is possible to prevent an impure gas such as carbon dioxide gas from developing from an electron-discharging substance applied to the filament coil 6, thereby suppressing the toxication of the entire electrode.

Title: Picture data re-transmission system
Inventor: YOKOYAMA NAMI
IPC: H04N1/403
Filed: 1989-08-22
Abstract: PURPOSE:To transmit again picture data without bothering the transmitting side by changing threshold by a density changing command from a receiving side. CONSTITUTION:When the receiving side receives obscure picture data and desires re-transmission, it calls (polling) the transmitting side, and informs the transmitting side of the density changing command and the re-transmission request of a picture. The threshold changing part 4 of the transmitting side changes the threshold of a binarizing part 3. Namely, if the received density is too thick, the level of the threshold needs only to be made higher so as to be difficult to become black, and if the received density is too thin, the level of the threshold needs only to be made lower so as to be easy to become black. Thus, the clear picture can be re-transmitted without bothering the transmitting side.

Filed: 1989-08-22
Abstract: PURPOSE:To enhance massage effect by controlling air amount control valves at the time of the circulation of bathtub water so that the intensity change is repeated in the jet stream from a jet nozzle by changing an air suction amount and the changes of the air amount control valves are shifted timewise. CONSTITUTION:When solenoid valves 8a, 8b are opened, respective, left and right jet nozzles 2 suck air through air suction pipes 7c, 7a and air suction pipes 7d, 7b and said air is mixed with jet water as air bubbles to form air bubble jet streams which are, in turn, introduced into a bathtub to generate jet air bubble streams. When the solenoid valves 8a, 8b are closed, since the air suction passages to the jet nozzles 2 are closed, jet streams composed of mere water streams are injected from the jet nozzles 2. As mentioned above, when the solenoid valves 8a, 8b are subjected to opening and closing operation within a short time by a controller 9, the injection of jet air bubbles becomes a state as if injected intermittently and the state of jet streams is given to a human body. By this method, massage effect is enhanced and a psychologically excellent pleasant feeling is obtained.
