Title: Halftone display method
Inventor: ISHIDA YOSHIHIRO
IPC: B41J2/52
Filed: 1984-05-10
Abstract: PURPOSE:To maintain the sharpness at a linear part by allocating the gradation levels of output dots of an output dot matrix so that the density distribution of the output dot matrix approximates to that of an input picture of an input dot matrix. CONSTITUTION:The picture data supplied to an input line 21 is written alternately to input data page buffers 23-1 and 23-2. An input buffer multiplexer 24 selects these picture data alternately and sends them to a signal line 25. A data processing part 26 processes the picture data for each input dot matrix and converts them into an output dot matrix. The data read out for each output dot matrix are written in output data buffers 32-1 and 32-2. When gradation levels of a page are written, these levels are read out for every line. Then the halftone is regenerated at a recording part 36 through the digital recording.

Title: Card type key holder and manufacture thereof
Inventor: SUGIHARA SUSUMU
IPC: A45C11/32
Filed: 1989-04-11
Abstract: PURPOSE:To surely hold a key without providing a locking holding means on the key by forming an inclined surface to contact with the key in a determined position of the inner surface of the key inserting hole of a key holder. CONSTITUTION:A determined position of the inner surface 4g of a key inserting hole 4a is formed into an inclined surface inclined from the key holder surface side to the back surface side, and the inclined surface is roughly constituted in such a manner that it contacts with the side surface of a key 3 to lockingly hold the key 3 in the key inserting hole 4a. Thus, when inserted into the key inserting hole 4a, the key 3 is lockingly held in the key inserting hole 4a by the frictional force between its side surface and the key inserting hole 4a inner surface. Hence, in a key holder, the key 3 can be lockingly held without providing any particular locking holding means on the key 3 and the key holder.

Title: Communication equipment
Inventor: MIZUTANI KOICHI
IPC: H04M9/00
Filed: 1988-04-15
Abstract: PURPOSE:To efficiently transmit a voice signal of AC component to a line side by providing a constant current circuit connected in parallel with a matching transformer for speech via a coupling capacitor and which passes the DC component of a speech signal from a communication terminal. CONSTITUTION:The constant current circuit 4 is connected in parallel with the transformer 1 via the capacitor 3, and a speech current is passed. And the constant current circuit 4 is constituted of a transistor 41 biased to an area representing a constant current characteristic. When the transistor 41 performs a constant current operation, the AC impedance of the transistor is heightened almost infinitely, therefore, no loss in the voice signal of AC component is generated, and it flows to the transformer 1 via the capacitor 3, then, is transmitted to a line. The speech current that is a DC component flows quickly through the transistor with the constant operation. In such a way, it is possible to take out the voice signal to be superposed. Also, since high impedance is generated in point of AC current, the voice signal of AC component flows to the transformer 1 without generating any loss.
