Title: Metal vapor discharge lamp with built-in starter
Inventor: TAKAI YOSHINORI
IPC: H01J61/56
Filed: 1979-10-31
Abstract: PURPOSE:To enable the prevention of the fusing between each contact of the bimetal piece and the contact piece of a heat-responsive element, by fixing the end of the bimetal piece and the contact piece on a base plate; these two pieces stand opposite and touch each other. CONSTITUTION:When a metal vapor discharge lamp with a built-in starter is supplied with power source, the self-heating of a heat-operated device 18 and the heat of a heating filament 22 bring about the operation of the heat-operated device 18, which initiates the main discharge between main electrodes to light the lamp. Since the end of a bimetal piece 18b and a contact piece 18d which make up the heat- responsive device 18 is bent to form a right angle and is fixed to a base plate 24, the bimetal piece 18b and the contact piece 18d can be held firmly and the contact pressure between these two pieces can be easily adjusted. In addition, since each part of the surface of the bimetal piece 18b and the contact piece 18d are made in contact with each other, the local wear and the fusing of contact materials due to small discharge between contacts, such as a movable contact 18c and a fixed contact 18e, can be obviated.

Title: Document retrieval device
Inventor: ITO MASAO
IPC: G06F17/30
Filed: 1990-05-30
Abstract: PURPOSE:To reduce retrieval time since a comparison character can be decided from the frequency distribution of a document data character by previously sorting a head character code in an ascending order and executing a preprocessing so that two division retrieval can be executed. CONSTITUTION:At first, the preprocessing is executed in a preprocessing part 1 from plural retrieval character strings, and the character code at the time of two division retrieval and a retrieval character code are inputted to a same comparison storage area 3, whereby the discrimination is inputted to a control information storage area 2. Then, a comparison character code is compared with the character code of document data. A comparison instruction in that case is designated from the storage part 2. Consequently, one of two address signals 20 and 21 outputted from the storage part 2 is selected in an address control part 4 based on a comparison result 19, and the increase of the address of a document data base is decided by the comparison result 19 and a signal 15 permitting the increase of an address increase part 6, which is outputted from the storage part 2. Thus, the character code executing two division retriev al by the appearing frequency of the character code is decided and the number of comparison times is reduced.

Title: High purity titanium target for sputtering and its production
Inventor: TERADA KATSUNORI
IPC: C22F1/18
Filed: 1995-06-07
Abstract: PURPOSE: To obtain a high purity titanium target for sputtering improved in step coverage and sputtering rate by specifying the purity, the particle diameter of a crystal grain and the orientation of the outer surface to suppress the genera tion of particles. CONSTITUTION: A high purity titanium bulk material >=4N5 in purity (impurities are metallic components) is forged at <=600 deg.C and rolled at <=450 deg.C. As a result, a high purity titanium plate >=4N5 in purity and ∞130 in initial hardness Hv (Vickers hardness) is obtained. Next, the plate is heat treated, for example, at 500±5 deg.C for 1hr to control the particle diameter and the orientation. As a result, the purity and the average particle diameter are controlled to respectively >=4N5 and <=20μm and the orientation of the crystal surface parallel to the outer surface is controlled in a range expressed by an inequality.

Abstract: PURPOSE:To constitute a simple and compact device, to mold the shapes of the components easily with resin and to reduce the production cost by forming a gear meshed with the rack of an operation ring and a member rotating unitedly with the gear and moving a lens holding frame by said rotating member. CONSTITUTION:The titled device consists of a fixed cylinder 1 fixed on a camera or the like, the operation ring 2 and a sliding cylinder 4 to be used also as a lens holding frame. A shaft 3c is penetrated freely turnable into the fixed cylinder 1 and the gear 3 meshed with the rack part 2a of the operation ring 2 and a rotary board 3a setting up a pin 3b to be inserted into the peripheral groove 4a of the lens holding frame 4 are fixed on one side of the shaft 3c and the other side respectively. A straight guiding plate 5 on which the lens holding frame 4 is set up so as to be driven straightly without rotation is straightly guided by a straight groove 1a formed on the fixed cylinder 1. When the operation ring 2 is rotated, the rack part 2a of the operation ring rotates the gear 3, so that the rotary board 3a fixed unitedly with the gear 3 is also rotated. Since the pin 3b set up in the rotary board 3b is inserted into the peripheral groove 3a of the lens holding frame 4, the rotation of the rotary board 3a slides the lens holding frame 4 forward and backward.

IPC: H02M3/00
Filed: 1988-06-07
Abstract: PURPOSE:To reduce the peak value of supply power by deviating basic pulses to perform pulse width modulation for each stabilizing circuit with a time lag. CONSTITUTION:A switching regulator is equipped with an astable DC power source 1 and stabilizing circuits 3-5. The stabilizing circuit 3 is then composed of a switching section 9, a high frequency transformer 10, a rectification circuit 11, a reference voltage 12, an error amplifier 13, a pulse width modulator 14 and a driver 15.

Abstract: PURPOSE:To easily improve the grade of a transmission capacity and to enhance the economy of the loop system by allocating a channel to a transmission line in such a way that an odd numbered address is allocated for an active channel and an even numbered address is allocated for a standby channel. CONSTITUTION:The channel allocation 2 for a transmission line 1 is implemented as an active channel W1, a standby channel S1, an active channel W2 and a standby channel WS2 from a high-order toward low-order. When a fault takes place at a point E of a loop system transmission line, a loopback switch 4 is used to loop back the active channels in the direction of the faulty point to an opposite direction standby channel at transmission stations C, B to avoid the faulty point of the transmission line. Since the active channels W1', W2' in the fault point direction in the transmission line between the transmission stations A, B are sent to standby channels S1, S2 in the opposite direction, the active channels W1, W1', W2, W2' are allocated from the high order toward the low order in the opposite direction after loopback.
