Title: Laser diode driving circuit
Inventor: KUSANO AKIHISA
IPC: H01S5/042
Filed: 1988-06-01
Abstract: PURPOSE:To reduce the deterioration in picture quality and to maintain the high-speed switching ability of a laser printer by providing 1st and 2nd transistors (Trs) which complementarily operate to each other, and making signals inputted to the bases of the Trs opposite in phase and almost the same in amplitude. CONSTITUTION:When the input signal of an AND gate 11 is '0', a transistor (Tr) 2 is turned of and another Tr 3 is turned on and, when the input signal is '1', the Tr 2 is turned on and Tr 3 is turned off, and base potential of the Trs 2 and 3 are made almost equal to each other when the Trs 2 and 3 are turned on. Therefore, the collector potential of the output Tr 6 of a constant- current circuit is stable, while it slightly varies when the input signal of the AND gate 11 is switched. Therefore, the deterioration of picture quality of a laser printer using laser diodes is reduced, and the reduction in service life of laser diodes to be caused by an overcurrent can be prevented. Moreover, the laser printer can maintain a high-speed switching ability.

IPC: G06F17/30
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To provide an information retrieval system which can improve a retrieval hit rate when one coincident with a condition to be designated by oneself is retrieved out of qualitative information which cannot be represented by a numeric value. SOLUTION: A management terminal 2 sorts qualitative information such as the customs and mottoes of a company according to plural evaluation items which are previously decided and displays the sorted evaluation items to urge the input of an evaluation value. Then, the inputted evaluation value is registered in a data base 21 in response to the concerned object data. When a retrieval request is given from a user terminal 3, the evaluation items are displayed and the input is urged for the desired evaluation value. When the evaluation value is inputted, based on the inputted evaluation value, a retrieval conditional expression is produced. A data base management part 24 retrieves the concerned object data based on the produced retrieval conditional expression.

Title: Chemical agent discharging device
Inventor: HIGUCHI YOSHIKA
IPC: A47K3/28
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To selectively use a plurality of chemical agents different from each other and enable these agents to be easily used simultaneously to increase the efficacy of the agents by providing a plurality of agent container parts storing the agents, a valve mechanism for selecting between the agent containers to allow passage of water and a discharging part positioned in the downstream of the valve mechanism. SOLUTION: Hot water is introduced from a water feed aperture 2 by opening a switch valve when this device is used. Next a dynamic pressure is made to act upon a slow injection membrane 21 of a chemical agent container corresponding to a chemical agent selection display part, and thereby the chemical agent is slowly injected to be mixed with the hot water. Thus, the mixed water is sprayed from a water spray part 6. In this case, the guide-out aperture 20 of the other agent container is blocked by a valve body 23 to prevent the other agent from being included into the hot water. When the agent supply is switched to the other agent, a body part 8 is rotated while a base part 5 is firmly held by a finger or otherwise so that the position of the agent selection display part is matched to an arrow on a ring 14.  Consequently, an agent container part 17 is rotated with the body part 8 to open the slow injection membrane 21 of the selected agent container so that the desired chemical agent can be made to flow out.

IPC: G11B9/14
Filed: 1993-05-13
Abstract: PURPOSE:To provide a measuring technology for interatomic microscope in which the irregularities of a sample can be separated well from the frictional force. CONSTITUTION:An oscillator for causing lateral oscillation relatively between a sample 8 and a probe 4 is provided. The sample 8 is oscillated laterally to excite bending or torsional oscillation in a cantilever 11. The phase and the amplitude of the oscillation thus excited are measured simultaneously and the measurements are employed in the formation of oscillation amplitude image and oscillation phase image. When the sample 8 is oscillated laterally, bending displacement and torsional angle of the cantilever 11 oscillate around the balance position thereof. The amplitude and phase of torsional oscillation are affected significantly by the frictional force as compared with the gradient. Consequently, an image reflecting the frictional force significantly can be obtained by measuring and recording the amplitude and phase of torsional oscillation.
