Title: Microstrip antenna
Inventor: KARASUYAMA ICHIRO
IPC: H01Q21/00
Filed: 1988-12-29
Abstract: PURPOSE:To obtain the directivity of a desired conical beam with small size and simple constitution at plural frequency bands by laminating plural disk conductor via a dielectric layer on a ground conductor respectively, feeding the center and applying offset feeding to other disk conductors. CONSTITUTION:Plural conductor disks 13, 15 are arranged concentrically sequentially in the order of larger diameter via dielectric layers 12, 14 of low loss on a grounded conductor flat plate 11 respectively, a feeding point 15f is provided to the center of the conductor disk 15 with a minimum diameter and feeding points 13f1, 13f2 are provided to a position parted from the center of other conductor disk 13 respectively. Thus, the disk conductor 15 with a minimum diameter becomes the radiation element of the highest frequency band, the other disk conductor 13 is the ground conductor 11 with respect to the adjacent small diameter disk conductor 15 and becomes the radiation element of a frequency band lowered sequentially. Thus, the desired conical beam directivity is obtained in plural frequency bands with small size and simple constitution.

Title: Image forming device
Inventor: HIRAI KATSUAKI
IPC: G03G21/14
Filed: 1993-12-27
Abstract: PURPOSE:To improve the transfer paper producing ability (productivity) by executing prallel copy mode without controlling the paper interval and retraction on the side of an original-carrying device. CONSTITUTION:A third movable mirror 204 is disposed in an optical path between a second mirror group 203, for use in the scan of the image of an original, and photoreceptor 205 of the main body 200 of an image forming device (copying machine) with an original-carrying device 100 set on a platen (original- placing glass) 201. When a second copy is taken in the parallel copy mode, the third mirror 204 is driven to retract from the optical path, thereby changing an image-forming position on the photoreceptor 205. Because the drive of the third mirror 204 is controlled, the need to control the paper interval and retraction in the original-carrying device obviated. Also, the same effect can be obtained by moving the third mirror 204 horizontally or rotating it.

Title: Disk recording method and audio data delimiting position adjusting device
Inventor: YOKOTA TEPPEI
IPC: G11B27/30
Filed: 1992-11-18
Abstract: PURPOSE:To facilitate adjustment of delimiting position of audio data after recording by connecting preceding and succeeding data to audio data for forming unit data and for continuous recording and at the same time recording the delimiting position information. CONSTITUTION:In recording and reproducing audio data, the audio data are recorded intermittently in units of cluster but are continuously recorded without changing the cluster even at the delimitation between programs while the audio data are continuously recorded. Namely, the final part of the first program and the head of the i+1-th program are recorded in one cluster. On the other hand, when a stop or a pause key is pressed during recording or halt, data recording is suspended by units of cluster and new data are recorded starting from a new cluster without connecting in the middle of the cluster when record mode is selected again. When the data do not reach one cluster, specific pattern data (0) are recorded for forming and recording one cluster and then the positions of the final data of i-th program and the head data of 1+1-th program are stored.

Title: Printing method
Inventor: YAMAUCHI YOSHIHIRO
IPC: G06K15/12
Filed: 1987-12-28
Abstract: PURPOSE:To prevent difference in sizes of printed materials when printing data, which have the different resolution but have the same size, are printed, by changing the frequency of the reference clock of writing data, and adjusting the sizes of the picture elements of the writing data. CONSTITUTION:The frequency of a shift clock in a shift register, which transmits printing data into a laser printer, is adjusted. The size of one dot of a picture element itself is changed, and the printing data undergo variable power. For example, when a received document of 200 dpi through a GIII FAX is printed with the laser printer of 300 dpi, the frequency of a video clock is divided by 2/3. The clock, whose frequency is multiplied by 3/2, is used. The size per picture element is expanded by 3/2 times of the original size. This is equal to the case when a received document of 300 dpi is printed. Since the vertical direction cannot be adjusted in this way, the same data as the data in the line immediately before are inserted as the next line once in two lines in order to multiply the data by, e.g., 3/2 times. Thus the two lines are increased to three lines. This method and the like are used.

Title: Ring network communication equipment
Inventor: YAMA TETSUO
IPC: H04Q7/38
Filed: 1993-12-27
Abstract: PURPOSE:To attain efficient communication and access to a fixed line even when a terminal equipment moves among nodes by using only a data exchange function in a ring network and a changeover function in a radio base station so as to switch a channel when a position of a mobile station is registered and the mobile station is moved. CONSTITUTION:Radio base stations 4-10 measure electric field strength with all mobile stations at all times and sends the information as position data in a ring network to extract position information of an optional mobile station from any of the stations 4-10 through the network. When an exchange station 2 calls a mobile station 4, the exchange station 2 sends information to call the mobile station 4 by using control data on the network. A base station discriminating to be closest to a mobile station 11 based on positioned data sent always on the ring receives the call information to start communication with the mobile station 11. Conversely when the mobile station 11 calls the exchange station 2, a base station closest to the mobile station 11 starts calling. The base station receiving the call starts communication with the mobile station 11.

Title: Semiconductor non-volatile memory and manufacture thereof
Inventor: TAKEBUCHI MASATAKA
IPC: H01L21/8247
Filed: 1988-12-28
Abstract: PURPOSE:To prevent an erroneous operation of a memory at readout by a method wherein those among source lines or row lines to which a low bias voltage is usually given are set to be given a voltage positive to all cells at readout. CONSTITUTION:A voltage setting means 1 is provided to enable those among source lines 73-1 to 73-2 or row lines 74-1 to 74-3 to which a low bias voltage is usually given to be set to a voltage positive to all cells 71-1-1 to 71-1-3 at readout. By this setup, even cell transistors, whose threshold voltage becomes negative after erasure due to over-erasure even if an electron extraction condition is optimized at erasure, can be remedied by shifting their threshold voltage to a substantially positive value at readout, so that an erroneous selection can be prevented at readout and consequently an erroneous readout can be prevented.

Title: Key matrix input system
Inventor: SAEKI MASAYASU
IPC: G06F3/02
Filed: 1990-11-30
Abstract: PURPOSE:To reduce the generation of a rectangular wave and to prevent a noise from being generated by omitting a process wherein individual timing signals are outputted when no key is pressed in a process wherein the state of a switch input line is detected. CONSTITUTION:The output level of a timing signal line 3 is held in an invariably active, i.e., H(high) state. The levels of outputs K1 and K2 of a switch input line 4 are detected and when the both are nonactive, it is judged that none of the keys of a keyboard 1 is depressed. The individual timing signals T0-T3 are generated, individual deciding operation for whether there is a key depressed and where the key is depressed when so is interrupted, and nothing is done until a timing signal for key input for next detection is generated. Consequently, the generation of rectangular waves by many timing signals is reduced and the noise to an audio equipment is prevented from being generated.
