Title: Package of dehumidifying agent
Inventor: MIYASAKA TAKEHIDE
IPC: B65D30/02
Filed: 1988-10-20
Abstract: PURPOSE:To prevent the reduction of moisture absorbing ability by forming an inner bag with a water absorbing sheetlike body and an outer bag with a nonwoven fabric permeable to moisture but impermeable to water. CONSTITUTION:Steam present at the outside of a package of a dehumidifying agent passes through the moisture permeable parts 4 of the outer bag 3 of the package and the inner bag 2 and is absorbed in a moisture absorbing agent 1. Moisture meets with the passage resistance of the moisture permeable parts 4 and the inner bag 2 and reaches the moisture absorbing agent 1 and the amt. of moisture absorbed is limited. Since a large amt. of moisture is not quickly absorbed in the moisture absorbing agent 1, the moisture absorbing ability of the agent 1 is not reduced and packing work can be facilitated.

Title: Contact input signal processor
Inventor: TSUNODA TAKANORI
IPC: H02H3/05
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To greatly reduce unnecessary power consumption by making it possible to turn off a switching circuit at the time needed to inform a CPU of a contact state. SOLUTION: A switching circuit S" in the contact input signal processor is set in a normally-off state and a control circuit 1 turns on the switching circuit SW for a certain time when a contact state read command is sent from the CPU 2 to the control circuit 1. At this time, a DC voltage DC110 V is applied to contacts S1, S2 and Sn and the output signal of a photocoupler turns on for a contact in an on-state, so that the CPU 2 recognizes this state. Only when the switching circuit SW turns on with the contact state read command from the CPU 2, power consumption is generated at each contact input circuit and the command from the CPU 2 is almost momentary as compared with other processes of the CPU 2, so the total power consumption greatly decreases.

Title: Input system for character attribute code
Inventor: YAMAKITA TORU
IPC: G06F17/21
Filed: 1985-11-26
Abstract: PURPOSE:To improve the operability of a attribute code in a repeated input mode by stopping the repeated input at a position where the attribute code is already supplied in a continuous and repeated input mode of the attribute code. CONSTITUTION:When an underline, for example, is supplied, an underline key 1a is operated to read the data out of a memory 7 designated by a cursor pointer CP. Then the presence or absence of an underline code contained in the data is checked. If no underline code is contained in the data, an underline code is added to the character code stored in the memory 7 designated by the CP. Then the CP is replaced and the data is read out of an input buffer 2a. If an underline code is detected, the similar processing is repeated. Here the clear signal is delivered to an input control part 2 if an underline code is contained in the character code stored in the memory 7. Thus all processes are through.

Abstract: PURPOSE:To detect an electric power source condition of the terminal, to judge whether the communication is possible or not and to remove an unnecessary communication by installing an inquiry means to execute the general calling for respective terminals to an electronic computer and a means to respond to the calling to respective terminals. CONSTITUTION:When an inquiry means 12a of a computer 12 executes the general calling 15 to terminals 13 and 14, by returning responses 16a and 16b by response means 13a and 14a in accordance with the set procedure from terminals 13 and 14, the electronic computer 12 detects that an electric power source of the terminals 13 and 14 is present.
