Title: Formation of through-hole on base plate
Inventor: ORIGUCHI MAKOTO
IPC: B23K26/382
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a method of easily forming a straight through-hole on a base plate by means of a laser beam. SOLUTION: A pulsative laser beam L is emitted to an insulating base plate 10 in a state where a copper foil 11 having a surface roughness Ra of 0.1 μm is arranged on the rear side. The laser beam L is set so that its focal position f is above the irradiation surface of the insulating base plate 10. With the laser beam L emitted, it starts to form a hole in the depth direction from the surface of the insulating plate 10, and finally reaches the copper foil 11 to form a through-hole 13 (tapered hole). With the irradiation continued further, the laser beam L is reflected by the copper foil 11 to irradiate the inner circumferential face of the tapered hole. Therefore, the tapered hole is gradually expanded in diameter from the rear to the surface and finally becomes a straight through- hole 13.

Title: Secondary channel switching system for data communication
Inventor: OKITA RYOJI
IPC: H04L69/40
Filed: 1988-09-14
Abstract: PURPOSE:To transmit monitor information even during lookback by providing a line switching section switching a secondary channel independently of a main channel. CONSTITUTION:Secondary channels 22, 24 are switched independently of main channels 21, 23 by a line switching section 30 which is provided to a backup switching section 9 for a data exclusive line 3 and a standby line 7 when the secondary channels 22, 24 are used for the communication of monitor information of a monitor system monitoring the main channels 21, 23 of a MODEM network. Thus, even in the case of the lookback, even if the exclusive line 3 is not restored yet and changeover switches 31, 33 are thrown again to the position B, since the changeover switches 32, 34 are left connected to the secondary channel of the contact D, the transmission of monitor information is not disabled while the changeover switches 31, 33 are thrown to the position B.

Title: Power switch of electronic equipment
Inventor: TANAKA HIROYOSHI
IPC: G06F1/26
Filed: 1988-09-14
Abstract: PURPOSE:To cut off the supply of power to the peripheral devices which are not usually used and to prevent the malfunction of a power switch of an electronic equipment by using a subswitch operating means to permit or inhibit the operation of a main switch according to the ON/OFF operating positions of the subswitch. CONSTITUTION:A tip part 30b of a subswitch SSW operating part 30 permits the upward movement of a slide plate 20 only when an SSW 31 is kept ON. While the upward movement of the plate 20 is inhibited when the SSW 31 is kept OFF. Thus the plate 20 can move upward only when the SSW 31 is kept ON and the operation of a main switch MSW 22 is possible. Then the operation of the MSW 22 is inhibited by means of an interlock mechanism. The SSW 31 is turned on with push of the part 30 of the SSW 31 and the MSW 22 is turned on with push of an MSW operating part 21 after the plate 20 is moved upward.

Title: Semiconductor storage device
Inventor: KITAZAWA EIJI
IPC: G11C11/401
Filed: 1990-08-30
Abstract: PURPOSE:To end writing for clearing a memory cell within a short time by providing the semiconductor storage device with a switching means for selecting all word lines or plural word lines at the time of memory cell clearing writing operation based upon an output from an address selection circuit, and in other cases, selecting only one word line. CONSTITUTION:When a memory cell clear signal 1 is turned to a high level, the outputs of all OR gates 13 for positive and reverse phase addresses are turned to the high level independently of the input information of an external address terminal. When these output signals are inputted to a word line decoder 12, all address positive/reverse phase signals are turned to the high level and data are written in all selected cells. Since the address positive/reverse phase signals in normal operation are held at reverse phase relation to a memory cell clear state, the decoder 12 executes operation for selecting only one word line out of plural lines. Consequently, the memory cell clearing writing operation can be ended only by one operation.

Abstract: PURPOSE:To avoid all position registration stations from being revised due to part of addition and revision in the position registration zone by registering a mobile equipment number given based on position registration zone information given from a mobile exchange station or a subordinate layer position registration station. CONSTITUTION:A position registration station HM1 manages large position registration zones LZa1, LZa2 and a position registration station HM2 manages small position registration zones LZb1, LZb2. The position registration zones and the radio zones are configurated in a hierarchical way, and when a mobile set M is communicated with either a large radio zone or a small radio zone and the mobile set M is carried but not much moved, communication is implemented in the small radio zone and when the mobile speed is large such as movement in an automobile, communication is implemented by a large radio zone. Thus, lots of mobile sets M of a portable model are accommodated in a small radio zone and channel changeover number of times and position registration number of times for a mobile set M in the automobile mode during communication are reduced.

Abstract: PURPOSE:To protect the user program even when the programing tool is removed by providing the tool connecting confirming means to confirm the connection of the programing tool and the first and second writing prohibiting means to write to the storing means. CONSTITUTION:When the operating mode is designated by a program console 2, the user program is executed and the execution of the final END instruction of the user program is confirmed, a key input receiving processing to the program console 2 is executed, and next, respective types of reading are executed. Further, when the completion of the processing is confirmed, a trigger pulse 106 is outputted, supplied to an S input of a latch 14 through an inverter 16, consequently, a writing control signal 102 of a Q output comes to be always an H level, and therefore, the writing to a RAM 10 is always prohibited. Thus, since at the operating mode, the writing to the RAM 10 is always prohibited, the external electric load is driven and controlled by the execution of the user program, and even when the large noise occurs, the erroneous writing to the RAM 16 is prevented without fail.
