Title: Electric warming tool
Inventor: YAMAKITA TAKAHIKO
IPC: H05B3/20
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To lessen transfer of unnecessary heat to the floor surface with an electric warming tool such as an electric carpet even through introducing such a configuration that the entire surface of the warming tool comes into contact with the floor surface. SOLUTION: A heating element 2 as a heat source is embedded fast in a soft foaming body 9, and a cover 10 is set on the oversurface. The foaming body 9 is furnished with recesses 11 and projections 12 at the floor face and the oversurface. Because of surface unevenness, the contacting areas with the floor surface and a cover can be lessened in the amount corresponding to the recesses 11, compared with the total flat configuration. This decreases heat conduction to the floor surface and prevents it from discoloring, deformation, etc.

Title: Structure of rotary valve for trombone
Inventor: KONGOU AKIHIKO
IPC: G10D9/04
Filed: 1988-09-19
Abstract: PURPOSE:To reduce variation of the blowing feeling, tone quality, etc., of a trombone irrespective of the use of a by-pass tube by constituting the tube switching valve of the trombone of two interlocking 3-port rotary valves. CONSTITUTION:In this rotary valve structure of a trombone, switching between a by-pass tube 131 and main tubes 101 and 103 is performed by operating an operation link 127. When the link 127 is operated in the direction shown by the arrow, the valve rotor 111A of this rotary valve 111 turns 120 deg. through a flange section 112b. As the rotor 111A turns, a link 121 is pulled in the direction shown by the arrow through another flange section 112a. Therefore, the valve rotor 113A of another rotary valve 113 also turns 120 deg. in the direction shown by the arrow through the link 121 and a flange section 114. As a result, each rotor hole 133 and 135 moves and the main tube 101 and by-pas tube 131 are simultaneously communicated with the by-pass tube and main tube 103, respectively. Therefore, the radius of curvature for constituting the tubes can be increased and variation of the blowing feeling, tone quality, etc., of this trombone can be reduced.

Title: Test scan circuit device
Inventor: KADOWAKI YUKIO
IPC: G01R31/3185
Filed: 1990-09-04
Abstract: PURPOSE:To ensure latching by transferring data held by a master side latch to a slave side latch by means of raising of a data transfer clock at the time when there is no effect of clock skew. CONSTITUTION:One scan register comprises the respective clocks of normal scan and data transfer and a plurality of circuits each of which outputs scan data and the like in response to a scan disabling signal or a clock selecting signal. Plural stages of scan registers comprise a scan data output terminal 32 connected to the scan data input terminal of the multiplexer of the scan register of the next stage. Data held by a master side latch at time B is transferred to a slave side latch at time C by raising the data transfer clock to 1 at the time C when there is no effect of clock skew. A master side gate 5 is turned off at the time B and scan data transferred by the multiplexer 4 is made to flow to the slave side, preventing destruction of test vector. Generation of shift fault due to clock skew can thus be avoided irrespective of how the circuit of the scan register is arranged.

Title: Ventilating fan for duct
Inventor: ISHIZU TETSUO
IPC: F24F7/10
Filed: 1987-09-18
Abstract: PURPOSE:To permit the reduction of noise remarkably, by rotatably arranging a counterflow preventing shutter having a supporting point at the lower part of the delivery port of a ventilating casing. CONSTITUTION:A counterflow preventing shutter 7, having a supporting point 9 at the lower part of the delivery port 8, is arranged at the delivery port 8 of a ventilating casing 3. The shutter 7 is tilted about the supporting point 9 toward the lower side of a ventilating passage by the pressure of discharging air of a fan 2 and opens the ventilating passage from the upper side thereof. On the contrary, when the fan 2 is stopped, the shutter 7 is pushed up about the supporting point 9 by the weight of a balancer 11 therefor and closes the ventilating passage from the lower side of the passage. According to this method, the supporting point 9 of the shutter 7, which becomes an obstacle against ventilation, is not located at the upper side of the ventilating passage, whereat the flow speed of air is maximum; therefore, hissing sound will never be generated and noise generated from the ventilating fan may be reduced remarkably.

CONSTITUTION:A paper pattern Q of a slipper consists of a pair of right and left foot-shaped paper members 2 and an instep part 3 formed integrally there between. The instep part 3 is formed to have a foot inserted and hooked, and for making an entrance 5 larger so as to insert the foot easily, the instep part 3 is formed wider at the lower end, with a recess part 4 formed at the center of the lower end part. For making up a slipper P from the paper pattern Q, one foot-shaped member 2 is rotated by 180 deg. to be combined with and attached to the other foot-shaped paper member 2. A double foot-shaped plate 1 and the instep part 3 put between both ends of it are thus composed by connection of the foot-shaped members 2 with each other.

Title: Shift register
Inventor: MURAKAMI KENJI
IPC: G11C19/28
Filed: 1987-09-19
Abstract: PURPOSE:To operate normally even when a clock skew is occurring without enhancing chip area or power consumption by delaying data transmission between latch circuits by a half period of clock. CONSTITUTION:By inserting a p-channel transistor Tr between flip-flops FF1, FF2, the data transmission time from the flip-flop FF1 to the other FF2 can be delayed by 1/2 period of clock. Accordingly, a switch provided between the latch circuits can be made turned off by detecting an edge where a clock signal inputted to the latch circuit in the preceding stage is triggered, and can be made turned on by detecting an edge where said clock signal is not triggered, so that a sufficient delay time can be provided for the inter-latch circuit data transmission. As a result, a shift register that operate normally even at a time of clock skew can be obtained without enhancing chip area or power consumption.

Abstract: PURPOSE:To obtain a modulation system in response to a distance with plural process input/output controllers by providing an adaptor in parallel with a transmission/reception circuit of a master module of a central processing section from which data is transmitted to the process input/output controllers. CONSTITUTION:The adaptor 4 having a transmission/reception circuit 4a is provided with the transmission/reception circuit 3f in the master module 3 of the central processing section 1. Only when a transmission data output signal 3d is outputted from a data communication controller 3a, the circuits 3f, 4a are in the data transmission state to slave modules 21, 22, 31-33, 41-43, 51, 52 of the process input/output controllers, and in data reception standby state from the slave modules at the end of data transmission. Since the data is returned from the slave modules from a transmission line 80 or 90, a reception data input signal 3e of the controller 3a is either an output signal 3g or 4g in the circuits 3f, 4a. Since the adaptor 4 inputs a transmission/reception switching signal 3c from the controller 3a, the structure is simplified.
