IPC: G11B7/24
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide the optical disk recording medium where a pattern for judging a tilt quantity more in detail is recorded as to a recording medium for an optical disk player.

Title: Schmitt trigger circuit
Inventor: SEGAWA OSAMU
IPC: H03K3/3565
Filed: 1984-04-06
Abstract: PURPOSE:To determine an input threshold voltage independently by connecting the node of the drains of the 1st and 2nd inverters and the output of the 4th inverter to the input of the 3rd inverter and connecting the output of the 3rd inverter to the input of the 4th inverter. CONSTITUTION:If a signal having a saw tooth-like voltage waveform is applied to an input terminal 71, signal lines 72, 73 show a square voltage waveform. Since a p type TR45 and an n type TR47 are actuated during the period of t0- t1, t2-t3 and t4-t5 and an inverter 63 is not actuated, a signal line 74 is held at a voltage level having the same phase as that of a terminal 71 and a signal line 75 coincides with the inverted voltage of the terminal 71. During the period of t1-t2 and t3-t4, both the p type TR45 and n type TR47 are disconnected, and the inverter 63 operates normally. Therefore, the signal lines 74, 75 are held at the preceding state.

Title: Lighting device
Inventor: YAMAMOTO YASUHIRO
IPC: G03B27/54
Filed: 1987-03-24
Abstract: PURPOSE:To obtain a print less in image irregularity at all times by enabling a prism which is provided on the optical axis from a lighting lamp to an image to rotate around the optical axis. CONSTITUTION:A trapezoid prism 16 for illumination light rotation is held on a prism holder 17, which is installed rotatably on a holder 18. When this prism holder 17 is rotated, the prism 16 rotates around the optical axis (e) and illumination light rotates by an angle twice as large as the angle of rotation of the prism 16. The illumination light is therefore directed optionally by rotating the prism 16. When a laterally long image 31b is printed, the prism 16 is so rotated that the filament 1a of the illumination lamp 1 becomes laterally long, and consequently the filament 1a of the illumination lamp 1 also becomes laterally long in a laterally long lighting range; when a longitudinally long image is printed, the filament 1a of the illumination lamp 1a becomes longitudinally long in a longitudinally lighting range, so the print less in light quantity irregularity is obtained.

Abstract: PURPOSE:To operate an electronic range only when an electric heater is operated and increase a durability of an electrical connection by a method wherein a turn-table provided with an electric heater can slide between two positions, and when the turn-table is located at one position, a rotating force of a motor is applied and in turn when the turn-table is located at the other position, a plug is connected to a connector. CONSTITUTION:When a turn-table 7 is located at one position, a plug 10 is removed from a connector 11 and it is spaced apart from a side wall of a heating chamber 1. As a motor 8 is driven, its rotating force is transmitted to a turn-table 7 so as to operate as a high frequency range. In turn, when the range is operated as an oven range for scorching a food to be cooked, the turn-table 7 is rotated to bring the plug 11 at a position opposing to the connector 11. When the turn-table 7 is pushed backwardly, it is slid by a connecting pin 15 and a hook hole 16 from one position to the other. When the plug 10 is inserted into the connector 11, it is pushed by a projection 10' intergral with the plug to release a switch 12 and an electrical supplying for the motor 8 is terminated. Under this condition, heating and scorching is performed.

Title: Broadcast communication system
Inventor: OKUDA HIDENORI
IPC: H04L12/18
Filed: 1993-03-29
Abstract: PURPOSE:To enable a reception terminal equipment to set the reception condition for receiving broadcast communication without negotiation between the reception terminal equipment and an information source of a transmitter side when the reception condition is set for the reception terminal equipment receiving the broadcast communication service through a digital communication network. CONSTITUTION:A transmission signal is divided into blocks, and a communication parameter is set at each block to set a reception condition to a reception terminal equipment according to a predetermined rule. A reception terminal equipment identifies each delimiter of the transmission signal and extracts the communication parameter from each delimiter according to the prescribed rule and sets the parameter to itself. Even when the transmission of broadcast communication is started from a sender side, a new reception terminal equipment takes part in the reception of the broadcast communication. Thus, the opportunity of request of re-transmission is reduced, the communication network is effectively used and the satisfaction of the reception terminal equipment users is improved.

Title: Grounding current detection method for three-phase four-wire circuit
Inventor: SHIROYAMA KAZUMI
IPC: H02H3/347
Filed: 1993-03-30
Abstract: PURPOSE:To detect a grounding current of a three-phase four-wire circuit independently of a zero-phase current due to an unbalanced load. CONSTITUTION:Current transformers CT1 to CT4 are provided respectively for four wires of a three-phase four-wire circuit; all current transformers are connected together in parallel thereby creating four current transformer residual circuit 2; and a grounding current protection relay 51G is connected to this residual circuit. A zero-phase current due to an unbalanced load L1 of the three- phase four-wire circuit flows to a current transformer CT4 at the neutral line but not to the residual circuit 2. When a grounding accident F occurs, the grounding current flows to the grounding phase, so that a zero-phase current due to the grounding current IG flows to the residual circuit 2. Thus, the grounding current protection relay is operated only by the zero-phase current by the grounding current without being affected by the zero-phase current due to the unbalanced load L1.

Title: Gas diffusion testing method
Inventor: IDE YASUO
IPC: G01M9/06
Filed: 1985-04-04
Abstract: PURPOSE:To investigate the gas diffusion situation suitable to local natural conditions by fixing a terrain model in the air course of an air channel and discharging a gas at the constant position of the model while the air course is rotated based on an hourly distribution in a preset window direction. CONSTITUTION:A terrain table 4 on which the terrain model such as the model of a chimney is placed is installed in the center of the floor 3 of the air course 2 into which an air flow 1 generated by a fan 14 disposed between partitions 15 is blown. The side of the air course 2 is formed with reinforced glass. The floor 3 is supported circularly by supporting foundations 19 installed on a ground 18, and placed on an anti-friction roller 13. The frequency distribution of the direction in which a wind blows for one day at a local place is measured to create a window blowing figure, and the gas for tracer 17 is discharged from the model chimney 5 while the air course 2 including the fan 14 is rotated on the basis of the figure. Thus the diffusion due to the window blowing in all directions for one day can be simulated. Moreover a window speed can be added.
