Title: Integrted circuit constitution
Inventor: JIYOUZEFU JIEIMUZU KAAHIRU
IPC: H03K19/0175
Filed: 1988-10-17
Abstract: PURPOSE: To provide an integrated circuit capable of using high-speed cycle time by the driver circuit of high speed and high performance by using driver enable signals and reducing the switching activity for plural times of individual drivers or individual driver groups. CONSTITUTION: The driver group 170 constituted of the individual drivers 101-104 is entirely enabled at the point t1 of time by enable signals from a conductor 109. By the enable signals supplied to a line 110, a second driver group 180 is enabled at the point t2 of time after the same cycle. While the drivers of the groups 170 and 180 are switched, the four drivers of the group 210 are suspended. As a result, only the four pieces of the drivers are simultaneously switched by a common ground bus 100. That is, in the case of assuming that the four pieces of the drivers are a maximum number for not generating switching errors, since the limit is not broken, excessive noise is prevented from being connected to the suspended drivers of the group 210.

Filed: 1991-09-11
Abstract: PURPOSE:To enable forms to be easily cut at a cutting position of the forms by a method wherein after a specific time has elapsed from completion of printing of the forms, the forms are sent out to a forms cutting position and thereafter, are returned to a suitable printing position. CONSTITUTION:When a next data does not come for, for example, 2 seconds after completion of printing, a present printing position is stored in a storage inside a printer body and thereafter, forms are sent out to a cutting position of the forms. Then, if a user requires, after regulating finely the cutting position, the forms are cut according to necessity. When, for example, 8 seconds has elapsed in the case of completion of this sequence or the printer receives a data, the printer brings back the forms by performing reverse line feed. At that time, whether the forms are cut or not is judged with nonforms sensor. When the forms have been cut, the forms are sent out to a position of the top of the forms. When the forms have not been cut, the forms are returned to the stored printing position.

Title: Luminance adjusting circuit
Inventor: TAGIRI HIROKAZU
IPC: G09G3/12
Filed: 1994-10-25
Abstract: PURPOSE: To simplify constitution and to easily set luminance variably by providing a means which varies the number of lightening pulses with fixed period and width supplied to a light emitting element. CONSTITUTION: A unit period T including the lightening pulses P1-P3 is divided into four small periods A-D. The width and period of pulses P11-P13 are set equally and also, they are fixed. However, the phases of the pulses P11-P13 are set differently. The change of the luminance is performed by masking the pulses. In such a case, adjusting data is inputted to the inside of an ICI via a terminal 9. A timing generation circuit 11 outputs one or zero regarding the small periods A-D. When luminance 75% is set by an operating key 7, one is outputted to an output circuit 15 in the small periods A, B and C and zero in the small period D. A signal outputted to the output circuit 15 is supplied to AND circuits 12-14. Consequently, the pulses P11-P13 are nullified (masked) in the small period D, and they are not derived to output terminals 16-18.

Title: Terminal device for key input
Inventor: AYA HIDEAKI
IPC: G06F3/023
Filed: 1988-10-14
Abstract: PURPOSE:To make a terminal small by providing keys closely to one another and providing an input key decision means which accepts only one of two adjacent keys when the two adjacent keys are pressed at the same time. CONSTITUTION:Key tops 2a (2(3)a, 2(6)a, 2(9)a, and 2(#)a) are arranged adjacently at extremely small intervals and when a key is pressed while a finger is fallen as shown in a figure (like a finger 5), the key right in front of the key is sometimes pressed with the finger pad. Namely, the key 2(6) is pressed with the tip of the finger 5 in the figure, but the key 2(9) is also turned on with the finger pad at the same time. In this case, only the correct key input is accepted. For example, when two adjacent front and rear keys are pressed at the same time, it is considered that the inner key is a target key and the key before it is turned on with the finger pad from the inserting direction of the finger 5, thereby accepting the input of the inner key. Consequently, even when the keys are arranged at narrower intervals, the accurate input is enabled.

Title: Integrated circuit device
Inventor: YAMAGUCHI SEIICHI
IPC: H01L27/10
Filed: 1989-10-04
Abstract: PURPOSE:To easily confirm the operation of a high voltage generation circuit from outside by providing a high voltage detection circuit detecting the output state of the high voltage generation circuit and outputting a detected result to the external terminals. CONSTITUTION:A mode setting circuit generates a control signal operating the high voltage generation circuit 2 by the state of the external terminal 10. When the high voltage generation circuit 2 normally operates and it generates a high voltage, the high voltage detection circuit 9 detects it and outputs an H-level. At that time, a selector 8 selects the output of the high voltage detection circuit 9 by the control signal outputted from the mode setting circuit, and outputs the H-level to the external terminal 11 through an output buffer 6. When the high voltage is not generated, an L-level is outputted to the external terminal 11 since the output of the high voltage detection circuit 9 is 'L'. Thus, it can be confirmed from outside whether the high voltage generation circuit 2 normally operates or not.

Title: Drive control method for railed cart
Inventor: HORI MASAYOSHI
IPC: G05D3/12
Filed: 1990-10-01
Abstract: PURPOSE:To improve the carrying efficiency of a railed cart by always setting a proper low speed drive time before a stop point. CONSTITUTION:In a test run of a railed cart 1, a drive control means 11 detects and stores the position of a stop point. That is, the means 11 stores the stop point and also recognizes the driving distance and the driving speed at all times and therefore operates a proper slow-down point based on the data on the stop point which is decided by a certain carrying request in a carrying state. In this case, an arithmetic formula is decided so that the speed of the cart 1 is slowed down right before the stop point. Thus it is possible to stop the cart 1 at the stop point in a short low speed drive time regardless of the state of the cart 1. Then an effective carrying job is attained by the cart 1.

Filed: 1990-10-01
Abstract: PURPOSE:To allow a feeding rotator to secure an initial condition, when a sheet material is supplied, by detecting the phase of the feeding rotator through a second detecting means. CONSTITUTION:When recording is started, a sheet material 3 is intermittently carried by the reciprocation of a carriage 2 every time recording is conducted for one line. In this case, a third detector 39 detects whether the carriage 2 is waiting in the home position. When the carriage 2 is waiting in the home position, it is to be judged whether a second detector 9j is in the ON state. When the second detector 9j is in the OFF state, a second drive motor 16 is rotated and a position cam 9k mounted coaxially with a rotating shaft 9g1 is rotated until the second detector 9j is in the ON state. When the second detector 9j is in the ON state, an initial condition is confirmed so that the detecting operation is over.
