Abstract: An optical characteristic of an eye is obtained which can not be measured through a uniform adjustment because of a large difference in the distribution of a refractive index, or the like. An arithmetic part first selects an interlock mode, and performs an alignment adjustment. Next, the arithmetic part measures refraction, and interlocks and moves a first illumination optical system and a first light receiving optical system on the basis of the refraction. The arithmetic part obtains a density distribution of point images obtained from a first light receiving part, and judges whether a measurement can be made for each area on the basis of the density. The arithmetic part makes an adjustment so that an unmeasurable area becomes measurable, and creates a composite point image from plural signals obtained in a process of the adjustment. Further, the arithmetic part uses the composite point image to perform a Zernike analysis, obtains the optical characteristic and outputs it on a display part or the like.

Abstract: There is provided an ophthalmic measuring apparatus in which an image obtained by refractive wavefront measurement is adjusted to an image more suitable for analysis, and the refractive wavefront measurement with high accuracy is enabled. A first movement unit for moving a condensing position so that a light flux from a first light source is condensed on a place close to the retina of a subject eye, and a second movement unit for optically moving a first conversion member for condensing a light flux reflected by an retina of the subject eye and a first light receiving part for receiving light fluxes can be independently driven and can be further driven by an operation of an operator. First, an arithmetic part adjusts a projection side and a light receiving side on the basis of first received light signals from the first light receiving part (S101˜S105).

Abstract: A semiconductor memory device having a self refresh mode may enter the self refresh mode in response to a self refresh set command and may be released from the self-refresh mode in response to a self refresh release command. The self refresh release command may include a plurality of self refresh release commands sequentially executed while a clock enable signal (CKE) is in a clock enable state. In this way, noise on a clock enable signal may not erroneously release the self refresh mode and the reliability of the self refresh mode may be improved.

Abstract: A commercial according to user's needs is provided. A sponsor produces various commercials targeted to unspecified users. Each commercial data is attached with attachment data indicating the sponsor's idea of user and distributed to a large number of unspecified users. A commercial processing apparatus on the user side compares pre-registered data set beforehand by a user and the attachment data in a commercial being distributed and determines whether or not the commercial satisfies the user's needs. In response to the determination that the commercial satisfies the user's needs, the commercial based on the commercial data being distributed is shown and stored in a storage portion as registered commercial data. In response to the determination that the commercial does not satisfy the user's needs, instead of the commercial being distributed a commercial based on registered commercial data already stored in a storage portion is shown.

Abstract: A television broadcast is received and the attributes of a program of content and a commercial are detected by a sound multiplex flag detection section 6. When attribute change from content to commercial is detected, a system controller 7 instructs a demultiplexing section 2 to switch the reception section to a different channel in the commercial time period. If attribute change from the commercial to the content is detected on the former channel after switching to the different channel, it is determined that the commercial time period end is reached, and the reception channel is restored to the former channel. When a predetermined time as the commercial time period elapses, it is determined that the commercial time period end is reached, and the reception channel is restored to the former channel.

Abstract: In a recording-reproducing apparatus for recording a broadcast program, electronic program guide data distributed through a broadcast network is stored in an electronic program guide data storage area 8b of a hard disk, etc. When the user, etc., specifies any desired broadcast program, a system controller 9 retrieves the attribute of the specified broadcast program from the electronic program guide data stored in the electronic program guide data storage area 8b, determines whether or not commercials can be cut for the specified broadcast program based on the retrieved attribute, and displays the determination result on a display section 15 of a remote controller 14. If the displayed determination result indicates that commercials can be cut and the user, etc., gives a command to cut commercials, commercials are cut; if the user, etc., gives a command not to cut commercials, the broadcast program is recorded in a record area 8a of the hard disk, etc.

Abstract: Distribution schedule time data contained in electronic program guide data distributed from a broadcast station (an information providing source) is stored in a preselection data storage area as preselection data, whereby preselection of content of any desired broadcast program is registered. After preselection of the content is registered, if electronic program guide data provides change of the distribution schedule time data of the preselected content, the preselection data is updated based on the data of the changed distribution schedule time, the preselection management is performed based on the updated preselection data, and the preselected content is recorded in a record area.

Abstract: In a test mode circuit, a latch circuit latches a test enable signal and address signals, and a decoder circuit decodes the address signals latched in the latch circuit in response to the test enable signal latched in the latch circuit to generate one of the test mode signals. A data mask terminal is connected to an input circuit for inputting a signal at the data mask terminal and generating a mask signal. A gate circuit is connected to the latch circuit or the decoder circuit and the input circuit. The gate circuit passes the test enable signal and the address signals or the test mode signals when the mask signal is inactive, and masks the same signals when the mask signal is active.

Abstract: A semiconductor storage device contains a row redundancy cell array in which redundancy cells are arranged in connection with redundancy word lines respectively and a memory cell array in which memory cells are arranged in connection with word lines respectively. In a normal operation mode, the word lines are sequentially activated in response to input addresses, so that stored information is read out from each of the memory cells of the memory cell array. If an input address coincides with a defective word line address designating a word line being connected with a defective memory cell within the memory cell array, a redundancy word line is selectively activated as a replacement of the word line which is inhibited from being activated, so that stored information is read out from each of the redundancy cells connected with the redundancy word line.

The second number is larger than the first number. A control circuit detects the word line level generating voltage and uses feedback to control the voltage to a definite level.
